Description

Technical Field

[0001] The invention relates to the technical field of fixtures, and in particular to an automated fixture for tool holder quenching and a use method thereof. Background Art

[0002] The shield machine cutter holder is used to install the roller cutter. The cutter holder consists of a left cutter holder and a right cutter holder. The left cutter holder and the right cutter holder have the same structure and both include an inner cutter holder and an outer cutter holder. Figure 1 and 2 The inner and outer tool holders need to be fixed together by riveting and welding. After riveting and welding, the designated positions need to be quenched. The surface to be quenched on the left tool holder is as follows: Figure 1 The surface to be quenched on the right tool holder is indicated at A in the middle. Figure 1 Indicated at B in the middle. The surface to be quenched is the plane that needs to be quenched. There are two planes that need to be quenched on the left and right tool holders.

[0003] Quenching is a metal heat treatment process that heats the metal workpiece to an appropriate temperature, holds it for a period of time, and then quickly cools it in a cooling medium such as water, oil or air to increase its hardness and strength. In the traditional quenching process, manually operated fixtures are usually used to fix the workpiece, which has the following limitations: manual adjustment of the fixture is required, which is labor-intensive and has low fixing efficiency; the stability of the fixture has a great influence on the quenching effect, and manual operation is difficult to ensure the stability of the fixture, resulting in unstable clamping force; high-precision quenching cannot be achieved, which limits the application scope of the quenching process.

[0004] Moreover, in the actual quenching process, the processing platform may have a certain inclination, that is, it is not a horizontal plane, which will cause the fixture to be tilted and not level. Since the quenching surface needs to be in a certain horizontality and verticality during the quenching process, the quenching surface can be fully and accurately quenched to ensure that a certain strength and hardness can be achieved.

[0005] Once the fixture is tilted, the workpiece will also be out of level, so it is difficult to ensure the consistency of the depth and shape distribution of the hardened layer of the workpiece during quenching, which may cause defects such as quenching deformation and cracks. Therefore, it has become an urgent problem for technicians in this field to develop an automated fixture for quenching and its use method to solve the problems of workpiece position accuracy and quenching quality, reduce labor intensity, and improve production efficiency. Summary of the invention

[0006] In order to solve the problems that traditional manual clamps have high operating intensity, low efficiency, and difficulty in ensuring the positioning accuracy of workpieces, the present invention provides an automated clamp for tool holder quenching and a method of using the same. First, the workpiece is adaptively adjusted horizontally according to its placement, and then the positioning operation is automatically performed according to the type of workpiece. The position of the workpiece can be quickly adjusted and the positioning accuracy can be ensured, ensuring that each batch of workpieces can be quenched in the best posture, thereby ensuring the consistency and stability of the quenching quality.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is: An automated fixture for tool holder quenching, which receives the left tool holder or the right tool holder transferred by an electromagnetic manipulator, comprises a fixture base plate, an adaptive level adjustment mechanism for adjusting the elevation and levelness of the tool holder, a lateral positioning component, a longitudinal positioning component, a clamping cylinder, a cross positioning mechanism and a detection sensor; The fixture bottom plate is provided with four said adaptive horizontal adjustment mechanisms arranged in a rectangular shape, so as to facilitate the horizontal adjustment of the tool holder, each of which comprises a height adjustment component, a horizontal adjustment component and a sensor group for detecting distance and pressure, the horizontal adjustment component is arranged on the height adjustment component, the horizontal adjustment component rises and falls with the height adjustment component, and the height adjustment component and the sensor group are arranged at intervals on the fixture bottom plate; The lateral positioning components are symmetrically arranged on the left and right sides of the clamp bottom plate, which is convenient for realizing the left and right positioning of the tool holder. Two groups of longitudinal positioning components are also arranged at intervals on the left and right sides of the clamp bottom plate. Both the lateral positioning component and the longitudinal positioning component include a cylinder and a positioning block. The clamp bottom plate is provided with a clamping cylinder for clamping and fixing the tool holder at the diagonal positions, which is convenient for clamping and fixing the tool holder after positioning. The cross positioning mechanism is arranged on the rear side of the fixture bottom plate, and the cross positioning mechanism slides left and right and front and back along the fixture bottom plate, so as to facilitate positioning of the position of the tool holder that needs to be quenched. A detection sensor for detecting the type of tool holder is arranged on the front side of the fixture bottom plate, so as to facilitate detection of whether the tool holder is a left tool holder or a right tool holder.

[0008] Furthermore, the fixture base plate is a double-layer plate frame structure, and the adaptive horizontal adjustment mechanism, lateral positioning assembly, longitudinal positioning assembly, cross positioning mechanism and detection sensor are arranged on the upper layer of the fixture base plate. The clamping cylinder is vertically arranged on the lower layer of the fixture base plate, and the upper layer of the clamping cylinder extends upward and extends out of the upper layer of the fixture base plate.

[0009] Furthermore, the adaptive horizontal adjustment mechanisms on the left and right sides of the clamp base plate are symmetrically arranged, and the adaptive adjustment mechanisms on the front and rear sides of the clamp base plate are also symmetrically arranged. The four adaptive horizontal adjustment mechanisms cooperate with the bearing knife seat to facilitate stable support of the knife seat.

[0010] Furthermore, the height adjustment assembly includes a height servo motor, a lower wedge-shaped base, a screw rod and an upper wedge-shaped slide, the screw rod is rotatably arranged on the lower wedge-shaped base, one end of the screw rod is gear-driven with the height servo motor, so as to facilitate driving the screw rod; The screw rod is meshed with the upper wedge-shaped slide, which is convenient for converting the rotation of the screw rod into the movement of the upper wedge-shaped slide. The upper wedge-shaped slide is slidably arranged above the lower wedge-shaped base, and the sliding surface between the upper wedge-shaped slide and the lower wedge-shaped base is an inclined surface and has an angle with the horizontal plane, so that the upper wedge-shaped slide is raised and lowered when sliding.

[0011] Furthermore, the horizontal adjustment assembly includes a horizontal servo motor, an electromagnetic clutch, a camshaft and a guide block. The camshaft is rotatably arranged on the upper wedge slide. The guide block is arranged on the fixture bottom plate on one side of the upper wedge slide. The horizontal servo motor is slidably arranged on the guide block. The sliding direction of the horizontal servo motor is the same as the sliding direction of the upper wedge slide, and the sliding speed is consistent. That is, when the upper wedge slide slides, the horizontal adjustment assembly is driven to slide together. The electromagnetic clutch is arranged between the output shaft of the horizontal servo motor and the camshaft to facilitate locking and unlocking the camshaft. The camshaft contacts the bottom surface of the tool holder, and the rotation of the camshaft can realize the horizontal adjustment of the tool holder.

[0012] Furthermore, the sensor group and the guide block correspond to each other on the left and right, and the sensor group includes a sensor bracket, a pressure sensor and a distance sensor. The pressure sensor and the distance sensor are respectively arranged on both sides of the sensor bracket, which can accurately detect the horizontality of the tool holder.

[0013] Furthermore, an adaptive horizontal adjustment mechanism is arranged between the lateral positioning components on both sides, the cylinder in the lateral positioning component is a lateral cylinder, the positioning block in the lateral positioning component is a lateral positioning block, and the lateral positioning blocks are symmetrically arranged on the front and rear sides of the lateral cylinder; The cylinder in the longitudinal positioning assembly is a longitudinal cylinder, the positioning block in the longitudinal positioning assembly is a longitudinal positioning block, the longitudinal cylinder and the longitudinal positioning block are arranged in corresponding intervals front and back, and an adaptive horizontal adjustment mechanism is arranged between the longitudinal cylinder and the longitudinal positioning block.

[0014] Further, the cross positioning mechanism includes a transverse sliding assembly and a longitudinal sliding assembly, the transverse sliding assembly includes a transverse sliding cylinder, a transverse support plate controlled by the transverse sliding cylinder, and a limit assembly for limiting the movement of the transverse support plate, the transverse support plate slides left and right on the fixture bottom plate, and the longitudinal sliding assembly is arranged on the transverse support plate to facilitate the longitudinal sliding assembly to move left and right together; The longitudinal sliding assembly includes a longitudinal sliding cylinder and a positioning push plate controlled by the longitudinal sliding cylinder. The positioning push plate slides back and forth on the transverse support plate. The cross-section of the positioning push plate is a "convex" shape and is used for positioning the quenching surface of the tool holder.

[0015] The method for using the automated fixture for tool holder quenching, based on the automated fixture for tool holder quenching, comprises the following steps: Step 1, adaptive leveling of the tool holder: a permanent magnetic manipulator is used to place the tool holder horizontally between the four adaptive horizontal adjustment mechanisms, and the tool holder is supported by the horizontal adjustment component. At this time, the horizontal state of the tool holder is maintained by the permanent magnetic manipulator, and each sensor group detects the vertical distance value between the bottom corner position of the tool holder and the adaptive horizontal adjustment mechanism, and then compares the four distance values; If the four distance values ​​are the same, it means the tool holder is level and the permanent magnetic manipulator is withdrawn. If the four distance values ​​are different, it means the tool holder is not level. The horizontal adjustment component at the corresponding position is automatically controlled to start and adjust the level of the tool holder until the pressure values ​​detected by the four sensor groups are in a certain proportional relationship. Then the horizontal adjustment component stops and the permanent magnetic manipulator is withdrawn. Step 2, adjusting the quenching height of the tool holder: using the sensor group to detect the height of the tool holder, and adjusting the height of the tool holder according to the required height: starting the four height adjustment components at the same time, and jointly driving the tool holder to rise or fall horizontally, until the required quenching height is reached, the four height adjustment components stop at the same time; Step 3: Horizontal and vertical positioning of the tool holder: First, use the detection sensor to detect whether the tool holder is a left tool holder or a right tool holder, and control different action processes according to different tool holder types; If it is the left tool holder: the cylinder in the left lateral positioning assembly extends to push the left tool holder to the right until the left tool holder abuts against the positioning block in the right lateral positioning assembly, and then the cylinders in the two longitudinal positioning assemblies are simultaneously started to push the left tool holder backward until the left tool holder abuts against the positioning blocks in the two longitudinal positioning assemblies; Next, the longitudinal sliding assembly starts, driving the positioning push plate to move forward until the positioning push plate contacts the position of the left tool holder that needs to be quenched, the cylinder in the lateral positioning assembly on the left side retracts, and the cylinder in the lateral positioning assembly on the right side extends, pushing the left tool holder to the side of the positioning push plate, thereby realizing the positioning of the two positions on the left tool holder that need to be quenched; If it is the right tool holder: the transverse sliding assembly is started, driving the longitudinal sliding assembly to move to the left, until the transverse sliding assembly abuts against the limit assembly; the cylinder in the transverse positioning assembly on the right side extends, pushing the right tool holder to the left, until the right tool holder abuts against the positioning block in the transverse positioning assembly on the left side; and then the cylinders in the two longitudinal positioning assemblies are started at the same time to push the right tool holder backward, until the right tool holder abuts against the positioning blocks in the two longitudinal positioning assemblies; Next, the longitudinal sliding assembly starts, driving the positioning push plate to move forward until the positioning push plate contacts the position of the right tool holder that needs to be quenched; the cylinder in the transverse positioning assembly on the right side retracts, and the cylinder in the transverse positioning assembly on the left side extends, pushing the right tool holder to the side of the positioning push plate, thereby realizing the positioning of the two positions on the right tool holder that need to be quenched; Step 4, fixation of the tool holder: after the tool holder is positioned horizontally and vertically, the two clamping cylinders are started simultaneously to cooperate in clamping the tool holder, and the remaining longitudinal positioning components, transverse positioning components and cross positioning mechanism are automatically reset.

[0016] Through the above technical solution, the beneficial effects of the present invention are: The present invention has a reasonable structural design, and uses the cooperation of four adaptive horizontal adjustment mechanisms to support the knife seat, which can provide a stable support for the knife seat. The adaptive horizontal adjustment mechanism has the function of adjusting the level and height. According to the distance and pressure detection feedback of the sensor group, it can automatically control the operation of the horizontal adjustment component at the corresponding position, and use the rotation of the camshaft to achieve fine adjustment of the inclination of the knife seat to ensure its level, meet the requirements of the horizontality and verticality of the quenching position, so that the quenching surface can be fully and accurately quenched to ensure that a certain strength and hardness can be achieved.

[0017] The present invention can automatically control the synchronous operation of four height adjustment components based on the distance and pressure detection feedback of the sensor group. The rotation of the height servo motor is finally converted into the movement of the screw rod, which finally drives the movement of the upper wedge slide. The change in the relative position of the upper wedge slide and the lower wedge base is utilized to conveniently lift or lower the tool holder as a whole, so as to adjust the height of the surface to be quenched to meet the height requirement of the quenching position.

[0018] The present invention utilizes the cooperation of the lateral positioning component and the longitudinal positioning component to quickly realize the lateral and longitudinal positioning of the entire tool holder. At the same time, the cross positioning mechanism can move horizontally and vertically, and the shape of the positioning push plate therein is adapted to the shape of the position of the tool holder to be quenched, which can facilitate accurate positioning of the position of the tool holder to be quenched, and realize automatic positioning of the position of the position to be quenched. After positioning, the tool holder can be pressed from the diagonal position by using a pressing cylinder to make it firmly fixed.

[0019] The present invention can realize adaptive horizontal adjustment and automatic fast and accurate positioning and clamping, and can ensure the consistency of the depth and shape distribution of the hardened layer of the tool holder after quenching. The adaptive horizontal adjustment mechanism can sense and automatically correct the slight position deviation of the workpiece in real time, ensuring that each batch of workpieces can enter the quenching medium in the best posture, thereby ensuring the consistency and stability of the quenching quality.

[0020] The present invention avoids the problem of uneven quenching caused by incorrect workpiece position through high-precision horizontal adjustment, effectively reduces defects such as quenching deformation and cracks, and improves the mechanical properties and appearance quality of the workpiece. At the same time, the adaptive adjustment ensures the comprehensive and uniform contact of the workpiece in the quenching medium, helps to achieve a more uniform temperature distribution, and further improves the uniformity and controllability of the quenching effect.

[0021] The automated design of the present invention greatly reduces manual intervention and achieves continuity and high efficiency of the quenching process. The operator only needs to set the program, and the fixture can automatically complete the clamping, positioning and horizontal adjustment of the workpiece, significantly improving the overall efficiency of the production line. Automated operation reduces the need for workers to carry heavy objects and make manual adjustments, reduces labor intensity, and protects the health of workers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings: like Figure 3~Figure 11 As shown, the automated fixture for tool holder quenching receives the left tool holder 1 or the right tool holder 2 transported by the electromagnetic manipulator 6, that is, the electromagnetic manipulator 6 is used to transport the left tool holder 1 or the right tool holder 2 and place it on the automated fixture, and the automated fixture realizes fast and reliable clamping and fixing of the left tool holder 1 or the right tool holder 2.

[0038] The automated fixture includes a fixture base plate 7, an adaptive horizontal adjustment mechanism 8 for adjusting the elevation and levelness of the tool holder, a lateral positioning component 9, a longitudinal positioning component 10, a pressing cylinder 11, a cross positioning mechanism 12, and a detection sensor 13. The automated fixture further includes a control cabinet, which is electrically connected to the adaptive horizontal adjustment mechanism 8, the lateral positioning component 9, the longitudinal positioning component 10, the pressing cylinder 11, the cross positioning mechanism 12, and the detection sensor 13, and all are controlled by the control cabinet to operate and feedback detection signals to the control cabinet.

[0039] The fixture base plate 7 is overall rectangular, and the fixture base plate 7 has a double-layer plate frame structure. The upper layer of the fixture base plate 7 is arranged with the adaptive horizontal adjustment mechanism 8, the lateral positioning component 9, the longitudinal positioning component 10, the cross positioning mechanism 12, and the detection sensor 13.

[0040] Four adaptive horizontal adjustment mechanisms 8 arranged in a rectangular pattern are provided on the fixture base plate 7. The adaptive horizontal adjustment mechanisms 8 on the left and right sides of the fixture base plate 7 are symmetrically arranged, and the adaptive adjustment mechanisms on the front and back sides of the fixture base plate 7 are also symmetrically arranged. Through the cooperation of the four adaptive horizontal adjustment mechanisms 8, they jointly carry the tool holder, and the tool holder can be the left tool holder 1 or the right tool holder 2.

[0041] The adaptive horizontal adjustment mechanism 8 has the functions of height adjustment and horizontal adjustment. Each adaptive horizontal adjustment mechanism 8 includes a height adjustment component 81, a horizontal adjustment component 82, and a sensor group 83 for detecting distance and pressure. The height adjustment component 81 is used for adjusting the height of the tool holder. The height adjustment component 81 includes a height servo motor 14, a lower wedge-shaped base 15, a screw rod 16, and an upper wedge-shaped sliding seat 17. The cross-section of the lower wedge-shaped base 15 is in a "匚" shape, and the lower wedge-shaped base 15 is fixed on the fixture base plate 7.

[0042] The screw rod 16 is rotatably arranged on the lower wedge-shaped base 15. The screw rod 16 has threads, and the screw rod 16 can rotate circumferentially on the lower wedge-shaped base 15, but the screw rod 16 will not slide vertically up and down along the lower wedge-shaped base 15, and the screw rod 16 will not move axially either. One end of the screw rod 16 is in gear transmission with the height servo motor 14. The height servo motor 14 is installed and fixed on the fixture base plate 7 through a motor bracket. The output shaft of the height servo motor 14 is connected with a small gear shaft 18 through a coupling. A large gear 19 is arranged at one end of the screw rod 16, and the small gear shaft 18 meshes with the large gear 19. Thus, the rotation of the screw rod 16 can be driven by the operation of the height servo motor 14.

[0043] The screw rod 16 meshes with the upper wedge-shaped sliding seat 17. The upper wedge-shaped sliding seat 17 is slidably arranged above the lower wedge-shaped base 15. The cross-section of the upper wedge-shaped sliding seat 17 is also in the shape of "匚". The sliding surface between the upper wedge-shaped sliding seat 17 and the lower wedge-shaped base 15 is an inclined plane and has an angle with the horizontal plane. Specifically, the top surfaces on both sides of the lower wedge-shaped base 15 are wedge-shaped surfaces 20, and the bottom surfaces on both sides of the upper wedge-shaped sliding seat 17 are also inclined wedge-shaped surfaces 20. The two wedge-shaped surfaces 20 above and below are in sliding contact, and the wedge-shaped surface 20 is the above-mentioned sliding surface.

[0044] After the screw rod 16 rotates forward, it drives the upper wedge-shaped sliding seat 17 to slide along the wedge-shaped surface 20 towards the side of the large gear 19. Under the restriction of the lower wedge-shaped base 15, the upper wedge-shaped sliding seat 17 is forced to rise, and thus a self-locking is formed between the lower wedge-shaped base 15 and the upper wedge-shaped sliding seat 17. If the screw rod 16 rotates in the reverse direction, the upper wedge-shaped sliding seat 17 will descend.

[0045] A horizontal adjustment component 82 is arranged on the height adjustment component 81, that is, the height adjustment component 81 will drive the horizontal adjustment component 82 to move up and down. The function of the horizontal adjustment component 82 is to adjust the levelness of the tool holder to keep it horizontal. The horizontal adjustment component 82 includes a horizontal servo motor 21, an electromagnetic clutch 22, a camshaft 23 and a guide block 24. The camshaft 23 is a cylindrical shaft, and two eccentric cams are arranged on it. The camshaft 23 is rotatably arranged on the upper wedge-shaped sliding seat 17, and the eccentric cams on the camshaft 23 are located at the middle position of the upper wedge-shaped sliding seat 17. After the tool holder is placed, the camshaft 23 contacts the bottom surface of the tool holder.

[0046] A guide block 24 is arranged on the fixture base plate 7 on one side of the upper wedge-shaped sliding seat 17. The guide block 24 is fixedly arranged and has a certain length. The guide block 24 and the lower wedge-shaped base 15 are arranged in parallel at intervals, and the top surface of the guide block 24 is the same as the top surface of the lower wedge-shaped base 15, both of which are inclined and have the same inclination angle. A horizontal servo motor 21 is slidably arranged on the guide block 24. The horizontal servo motor 21 is also slidably installed on the guide block 24 through a motor bracket. The sliding direction of the horizontal servo motor 21 is the same as the sliding direction of the upper wedge-shaped sliding seat 17 and has the same sliding speed.

[0047] An electromagnetic clutch 22 is arranged between the output shaft of the horizontal servo motor 21 and the camshaft 23. By energizing or de-energizing the electromagnetic clutch 22, the camshaft 23 can be locked or unlocked. After being locked, the camshaft 23 cannot rotate. After being unlocked, the camshaft 23 can be driven by the horizontal servo motor 21 to rotate normally. When the camshaft 23 rotates, the height around the bottom surface of the tool holder can be adjusted, so that the levelness of the tool holder can be automatically adjusted.

[0048] The height adjustment assembly 81 and the sensor group 83 are arranged at intervals on the fixture bottom plate 7. The sensor group 83 corresponds to the guide block 24 on the left and right. The sensor group 83 includes a sensor bracket 25, a pressure sensor 26 and a distance sensor 27. The pressure sensor 26 and the distance sensor 27 are respectively arranged on both sides of the sensor bracket 25. The pressure sensor 26 can measure the support pressure at the corner position of the tool holder, and the distance sensor 27 measures the vertical distance between the corner of the tool holder and the adaptive horizontal adjustment mechanism 8. Through the feedback of the detection signal of the sensor group 83, the operation of the height adjustment assembly 81 and the horizontal adjustment assembly 82 can be automatically controlled by the control cabinet.

[0049] The principle of the adaptive horizontal adjustment mechanism 8 is as follows: the left tool holder 1 and the right tool holder 2 are placed on the adaptive horizontal adjustment mechanism 8 by the magnetic claws of the permanent magnetic manipulator, which suck the workpiece and place it horizontally. When the processing platform 5 is uneven, that is, when there is a certain inclination, the camshaft 23 on the left side will first contact the bottom surface of the tool holder, and the camshaft 23 on the right side will not contact the bottom surface of the tool holder, and there is a height difference on both sides. At this time, the feedback from the distance sensors 27 on both sides shows that the value on the right side is different from the value on the left side, so the horizontal servo motor 21 in the adaptive horizontal adjustment mechanism 8 on the lower side, that is, the right side, starts to start and drives the camshaft 23 to rotate. The two eccentric cams on the camshaft 23 will gradually and slowly fine-tune the overall height of the right side of the tool holder through the rotation of the shaft, so that the height on both sides reaches the level. During the above fine-tuning process, the pressure sensor 26 on the right side will have numerical feedback. When the values ​​fed back by the pressure sensors 26 on both sides are in a certain proportional relationship, the horizontal servo motor 21 stops at this time, and the electromagnetic clutch 22 performs electromagnetic self-locking to achieve the locking of the camshaft 23, thereby achieving adaptive horizontal adjustment.

[0050] After the knife holder is adjusted in level and height, it needs to be positioned. Therefore, transverse positioning components 9 are symmetrically arranged on the left and right sides of the fixture bottom plate 7. Two groups of longitudinal positioning components 10 are also arranged at intervals on the left and right sides of the fixture bottom plate 7. Both the transverse positioning components 9 and the longitudinal positioning components 10 include cylinders and positioning blocks. The transverse positioning components 9 and the longitudinal positioning components 10 form a rectangle, and the area of ​​the rectangle is larger than the area of ​​the rectangle formed by the four adaptive horizontal adjustment mechanisms 8, that is, the transverse positioning components 9 and the longitudinal positioning components 10 are arranged outside the adaptive horizontal adjustment mechanism 8.

[0051] Specifically, the adaptive horizontal adjustment mechanism 8 is arranged between the lateral positioning components 9 on both sides, the cylinder in the lateral positioning component 9 is a lateral cylinder 91, the positioning block in the lateral positioning component 9 is a lateral positioning block 92, and the lateral positioning blocks 92 are symmetrically arranged on both sides of the lateral cylinder 91. The cylinder in the longitudinal positioning component 10 is a longitudinal cylinder 101, and the positioning block in the longitudinal positioning component 10 is a longitudinal positioning block 102. The longitudinal cylinder 101 and the longitudinal positioning block 102 are arranged in a corresponding interval in front and back, and the adaptive horizontal adjustment mechanism 8 is arranged between the longitudinal cylinder 101 and the longitudinal positioning block 102.

[0052] The lateral positioning assembly 9 on the right side can push the knife holder to the left side, and the lateral positioning assembly 9 on the left side can push the knife holder to the right side. The two longitudinal cylinders 101 extend simultaneously to push the knife holder backwards and make it rest on the longitudinal positioning block 102.

[0053] A cross positioning mechanism 12 is arranged at the rear side of the fixture bottom plate 7, and is used to position the part of the tool holder to be quenched, that is, to position the two quenched surfaces. The cross positioning mechanism 12 slides left and right and front and back along the fixture bottom plate 7, and thus the cross positioning mechanism 12 has a sliding function in the cross direction.

[0054] The cross positioning mechanism 12 includes a transverse sliding assembly 121 and a longitudinal sliding assembly 122. The transverse sliding assembly 121 includes a transverse sliding cylinder 28, a transverse support plate 29 controlled by the transverse sliding cylinder 28, and a limit assembly 30 for limiting the movement of the transverse support plate 29. The transverse support plate 29 slides left and right on the fixture bottom plate 7 through a slider rail structure, the piston rod of the transverse sliding cylinder 28 is connected to the transverse support plate 29 through a floating joint 31, and the longitudinal sliding assembly 122 is arranged on the transverse support plate 29.

[0055] After the lateral support plate 29 extends, it directly drives the lateral support plate 29 to move left, and then the longitudinal sliding assembly 122 moves with it. When the lateral support plate 29 abuts against the limiting assembly 30, it stops. The limiting assembly 30 includes a limiting bracket 301, a hydraulic buffer 302 and a limiting screw 303 arranged side by side on the limiting bracket 301. The hydraulic buffer 302 first buffers the lateral support plate 29, and the lateral support plate 29 finally abuts against the limiting screw 303 and stops. It should be noted that: for the positioning of the left tool holder 1, the operation of the lateral sliding assembly 121 is not required, and for the positioning of the right tool holder 2, the operation of the lateral sliding assembly 121 is required.

[0056] Whether the left tool holder 1 or the right tool holder 2 is positioned, the movement of the longitudinal sliding assembly 122 is required. The longitudinal sliding assembly 122 includes a longitudinal sliding cylinder 32 and a positioning push plate 33 controlled by the longitudinal sliding cylinder 32. The positioning push plate 33 slides forward and backward on the transverse support plate 29 through a slide rail slider structure. The longitudinal sliding cylinder 32 adopts a rodless cylinder. The positioning push plate 33 and the longitudinal sliding cylinder 32 are arranged up and down. The longitudinal sliding cylinder 32 can drive the positioning push plate 33 to move forward and backward in a straight line.

[0057] The cross section of the positioning push plate 33 is a "convex" shape and is used to position the quenching surface of the tool holder. When performing quenching processing, both the left tool holder 1 and the right tool holder 2 need to be quenched. The function of the longitudinal sliding component 122 is to drive the positioning push plate 33 to the position of the tool holder that needs to be quenched through the longitudinal sliding cylinder 32, so as to realize automatic and rapid positioning of the position that needs to be quenched.

[0058] After the tool holder has been adjusted horizontally and in height and has been precisely positioned, it is necessary to fix the position of the tool holder. A clamping cylinder 11 for clamping and fixing the tool holder is provided at the diagonal positions of the fixture base plate 7. The clamping cylinder 11 adopts an SMC CKZ3T50 series cylinder with a clamping arm, and the clamping cylinder 11 can clamp the diagonal position of the tool holder.

[0059] When the clamping cylinder 11 is installed, the clamping cylinder 11 is arranged vertically on the lower layer of the clamp bottom plate 7, and the upper part of the clamping cylinder 11 extends upward and out of the upper layer of the clamp bottom plate 7. The clamping arm of the clamping cylinder 11 can rotate to a certain angle. When the tool holder is not placed, the clamping arm is located on the side that will not interfere with the placement of the tool holder. After the tool holder is placed, the tool holder can be quickly clamped for clamping the tool holder. The clamping arm has a certain rotation angle.

[0060] The action flow of each component is different for the different types of the left tool holder 1 and the right tool holder 2. The control cabinet has two sets of fixed control flows for the left tool holder 1 and the right tool holder 2, which can control the sequential actions of the components. For this purpose, a detection sensor 13 for detecting the type of the tool holder is provided on the front side of the fixture bottom plate 7.

[0061] The detection sensor 13 adopts a diffuse reflection photoelectric sensor. The detection sensor 13 is fixed in position. The detection sensor 13 is used to emit light to determine whether it is blocked, to detect whether the left tool holder 1 or the right tool holder 2 is currently placed. The principle is: after the left tool holder 1 and the right tool holder 2 are placed, their structural positions are different; when the left tool holder 1 is placed, the detection sensor 13 corresponds to the groove on the left tool holder 1, and then the detection sensor 13 will not receive reflected light. When the right tool holder 2 is placed, the detection sensor 13 and the groove on the left tool holder 1 are offset, and then the detection sensor 13 can receive reflected light, thereby feeding back the detection signal to the control cabinet. After the control cabinet determines the type of tool holder, it controls the corresponding components to operate in sequence.

[0062] The principle of the present invention is as follows: the electromagnetic manipulator 6 grabs the tool holder for transfer and places it between the four adaptive horizontal adjustment mechanisms 8, and the camshaft 23 contacts the tool holder. The detection sensor 13 detects the type of tool holder and feeds back the detection signal to the control cabinet. The control cabinet first controls the horizontal adjustment component 82 to operate according to the detection signal of the sensor group 83 to keep the tool holder horizontal, and then controls the height adjustment component 81 to operate to raise and lower the tool holder to the specified height required for quenching. Then, according to the type of tool holder, the lateral positioning component 9, the longitudinal positioning component 10 and the cross positioning mechanism 12 are controlled to operate according to the corresponding process to realize the positioning of the tool holder. Finally, the clamping cylinder 11 is controlled to operate to clamp and fix the tool holder.

[0063] The present invention can realize the rapid clamping and loosening of the tool holder, and the adaptive adjustment of the level, and can ensure that the quenching process will not change due to the level, reduce the manual operation time, and improve the overall efficiency of the production line. It can ensure the stability and accuracy of the tool holder during the quenching process, and can reduce the direct contact of workers with dangerous environments such as high temperature and high pressure, thereby improving work safety.

[0064] like Figure 12~Figure 14 As shown, the method for using the automated fixture for tool holder quenching includes the following steps: Step 1, adaptive leveling of the knife seat: the knife seat is horizontally placed between the four adaptive level adjustment mechanisms 8 using a permanent magnetic manipulator, and the knife seat is supported by the camshaft 23 of the level adjustment assembly 82. At this time, the permanent magnetic manipulator is still connected to the knife seat to keep the knife seat in a horizontal state.

[0065] The distance measuring sensor 27 in each sensor group 83 detects the vertical distance value between the corner position of the bottom surface of the knife seat and the adaptive horizontal adjustment mechanism 8, and then feeds the detection data back to the control cabinet, so as to compare the four distance values. If the four distance values ​​are the same and the permanent magnetic manipulator is withdrawn, it means that the four horizontal adjustment components 82 can support the knife seat horizontally, ensuring the horizontal state of the knife seat.

[0066] If the four distance values ​​are different, it means that the fixture bottom plate 7 is tilted and cannot maintain horizontal support for the tool holder. At this time, the control cabinet automatically controls the horizontal adjustment component 82 at the corresponding position to start and drive the camshaft 23 to rotate, thereby adjusting the horizontality of the tool holder. During the adjustment process, the pressure sensor 26 in the sensor group 83 always detects the support pressure value until the pressure values ​​detected by the four sensor groups 83 are in a certain proportional relationship, and the horizontal adjustment component 82 stops running, indicating that the tool holder has been leveled. Finally, the permanent magnetic manipulator is withdrawn, which also ensures the horizontal state of the tool holder.

[0067] Step 2, adjustment of the quenching height of the tool holder: After ensuring the horizontal state of the tool holder, the distance sensor 27 in the sensor group 83 is used to detect the height of the tool holder, and the height of the tool holder is adjusted according to the required quenching height. Specifically, the four height adjustment components 81 are started at the same time, and the upper wedge slide 17 is driven by the screw rod 16 to move. The upper wedge slide 17 is forced to rise or fall on the lower wedge base 15, and then drives the horizontal adjustment component 82 to rise or fall, thereby driving the tool holder to rise or fall horizontally together, until the required quenching height is reached, and the four height adjustment components 81 stop moving at the same time.

[0068] Step 3, horizontal and vertical positioning of the tool holder: First, the detection signal of the detection sensor 13 is fed back to the control cabinet to determine whether the tool holder is the left tool holder 1 or the right tool holder 2. If the detection sensor 13 does not receive the reflected light, it is detected as the left tool holder 1, otherwise it is the right tool holder 2. Different action processes are controlled according to different tool holder types.

[0069] If it is the left tool holder 1: the cylinder in the left lateral positioning assembly 9 extends, that is, the left lateral cylinder 91 extends, and the left tool holder 1 is pushed rightward until the left tool holder 1 abuts against the positioning block in the right lateral positioning assembly 9, that is, against the two lateral positioning blocks 92 on the right. Then the cylinders in the two longitudinal positioning assemblies 10, that is, the longitudinal cylinders 101, are simultaneously started to push the left tool holder 1 backward until the left tool holder 1 abuts against the positioning blocks in the two longitudinal positioning assemblies 10, that is, against the longitudinal positioning blocks 102.

[0070] Next, the lateral sliding assembly 121 is stationary, the longitudinal sliding assembly 122 is started, and the longitudinal sliding cylinder 32 drives the positioning push plate 33 to move forward until the positioning push plate 33 is against the position to be quenched on the left tool holder 1. The cylinder in the lateral positioning assembly 9 on the left, that is, the lateral cylinder 91 on the left, retracts, and the cylinder in the lateral positioning assembly 9 on the right, that is, the lateral cylinder 91 on the right, extends, pushing the left tool holder 1 to the left to the side of the positioning push plate 33, thereby realizing the positioning of the two positions to be quenched on the left tool holder 1.

[0071] If it is determined to be the right tool holder 2: the transverse sliding assembly 121 is started, and the longitudinal sliding assembly 122 is driven to move to the left through the transverse support plate 29, until the transverse positioning plate in the transverse sliding assembly 121 abuts against the limit assembly 30. The cylinder in the transverse positioning assembly 9 on the right, that is, the transverse cylinder 91 on the right, extends to push the right tool holder 2 to the left, until the right tool holder 2 abuts against the positioning block in the transverse positioning assembly 9 on the left, that is, against the two transverse positioning blocks 92 on the left. Then the cylinders in the two longitudinal positioning assemblies 10, that is, the longitudinal cylinder 101, are started at the same time to push the right tool holder 2 backward, until the right tool holder 2 abuts against the positioning blocks in the two longitudinal positioning assemblies 10, that is, against the longitudinal positioning block 102.

[0072] Next, the longitudinal sliding assembly 122 is started, and the longitudinal sliding cylinder 32 drives the positioning push plate 33 to move forward until the positioning push plate 33 abuts against the position to be quenched on the right tool holder 2. The cylinder in the right transverse positioning assembly 9, that is, the right transverse cylinder 91, retracts, and the cylinder in the left transverse positioning assembly 9, that is, the left transverse cylinder 91, extends, pushing the right tool holder 2 to the right to the side of the positioning push plate 33, thereby achieving the positioning of the two positions to be quenched on the right tool holder 2.

[0073] Step 4, fixation of the knife holder: after the knife holder is positioned transversely and longitudinally, the two clamping cylinders 11 are started simultaneously to cooperate in clamping the knife holder, and the remaining longitudinal positioning components 10, transverse positioning components 9 and cross positioning mechanism 12 are automatically reset.
