Description

Technical Field

[0001] The present invention relates to the technical field of mechanical manufacturing and processing, and in particular to an automatic drilling device compatible with multiple types of panels. Background Art

[0002] The shift arm is an important part of the motorcycle speed shifting system, mainly used to connect the shift lever and the gearbox. However, since the shift arm is a non-standard part, the shift arms equipped on different models of motorcycles have significant differences in shape, size and inclination on the drilling surface. These differences lead to different processing angles of the spring hanging holes on the shift arm, which brings many challenges to production:

[0003] 1. High production cost: When processing different types of shift arms, existing drilling equipment needs to design special fixtures to ensure the level of the drilling surface. Due to the irregular shape of the shift arm, each model requires a specific fixture, which leads to a wide variety of fixtures and increases production costs. In addition, during the unloading process, there are also problems with the traditional manipulator or fixture structure. Although the manipulator is stable in grabbing and unloading, it also requires a large space to meet its motion trajectory. The overall structure of the processing device developed by the applicant is compact and cannot reserve a large space for the manipulator. The manipulator is prone to motion interference with other structures, and the cost of the manipulator is high; the use of fixtures for unloading requires the special design of corresponding fixtures, which is not only complex in structure, but also requires different fixtures for different types of shift arms, further pushing up the overall production cost and reducing economic benefits.

[0004] 2. Low processing quality: The batch processing volume of a single model of shift arm is usually not large, but in actual production, different models of products require frequent replacement of fixtures and adjustment of equipment. This frequent replacement and adjustment not only reduces processing efficiency, but also makes it difficult to ensure processing accuracy, thus affecting the quality of the final product. After each replacement of the fixture, the operator needs to adjust the accuracy of the equipment, which makes the processing process cumbersome and prone to errors, further reducing the processing quality.

[0005] 3. High professional requirements: The spring hanging hole of the shift arm has extremely high requirements for processing accuracy. After each replacement of the fixture, experienced operators are required to make fine adjustments to the equipment to ensure the accuracy of the drilling position. This not only increases the requirements for the professional skills of the operators, but also increases the training costs. Once the skilled operators leave, it is difficult to replace them, which affects the continuity and stability of production.

[0006] Therefore, it is urgent to design a drilling device with strong versatility, low processing cost and good quality for the shift arm. Summary of the invention

[0007] The present invention aims to provide an automated drilling device that is compatible with multiple types of panels to improve the processing efficiency and quality of a shift arm.

[0008] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an automatic drilling equipment compatible with multiple types of panels, comprising a rotating disk structure and a drilling unit, a grinding unit and a unloading unit fixed on a frame; a plurality of positioning units for fixing the workpiece are provided on the rotating disk structure, the positioning unit comprises a positioning tool and a clamping structure, the positioning tool is rotatably connected to the rotating disk structure and rotates in a vertical plane, and positioning holes are opened at both ends of the positioning tool and positioning pins are installed; an angle adjustment mechanism cooperating with the drilling unit is also provided on the frame, and the angle adjustment mechanism is used to adjust the rotation angle of the positioning tool; the drilling unit comprises a drilling drive structure and a drilling part, and the grinding unit comprises a grinding drive structure and a grinding part; the unloading unit comprises a material unloading lifting cylinder and a unloading cylinder, the movement paths of the two are perpendicular to each other, and positioning magnets are provided at the ends of the output shafts of the two.

[0009] The principles and advantages of this solution are:

[0010] 1. In actual application, this solution can adapt to a variety of different models and shapes of shift arms through the angle adjustment mechanism and the rotatable positioning fixture. This versatility reduces the need for specific fixtures, so that the same equipment can handle different types of shift arms. Secondly, the output shaft ends of the unloading lifting cylinder and the unloading cylinder of this solution are provided with positioning magnets. The positioning magnets magnetically adsorb the workpiece, so that the device can better adapt to the irregular shape of the shift arm. There is no need for complex manipulators or unloading fixture structures, which greatly simplifies the structure of the unloading unit. Compared with traditional drilling equipment and unloading devices, this solution effectively reduces the number and types of fixtures and unloading fixtures, improves the versatility of the equipment, and greatly reduces production costs.

[0011] 2. The positioning tooling of this solution realizes the unified clamping of multi-model workpieces, and the angle adjustment mechanism realizes precise angle adjustment according to different shift arm requirements to ensure the level of the drilling surface. The combination of the two effectively reduces manual equipment adjustment and reduces human errors, thereby ensuring the consistency and accuracy of processing and further improving product quality.

[0012] 3. This solution realizes automatic positioning, drilling processing and automatic unloading through the positioning unit, drilling unit, grinding unit and unloading unit. The high degree of automation and continuous operation capability of the drilling equipment effectively reduces the frequency of tooling fixture replacement and equipment adjustment, reduces downtime, and greatly improves production efficiency. The simplified operating procedures and efficient unloading system further improve the overall production efficiency.

[0013] 4. The highly versatile design reduces the need for specific tooling and fixtures, as well as the professional requirements for equipment adjustment. Operators only need to perform simple settings and monitoring, without the need for complex debugging techniques, reducing training costs. Novice operators can also quickly get started without affecting the continuity and stability of production.

[0014] Furthermore, the positioning holes at either end of the positioning tool are porous interconnected structures, and the top surface of either end protrudes upward and is higher than the top surface of the other end, so that the positioning tool is in an inverted L shape, and the lateral part of the inverted L-shaped structure is curved on the outward side.

[0015] The above-mentioned arrangement has the following effects: First, designing any locating hole into a multi-hole connected structure is conducive to determining the position of the locating pin at the movable end according to the actual shift arm model, ensuring that shift arms of various models can be fixed on the positioning tooling, realizing unified clamping and automated processing of multiple products, and reducing production costs; second, some models of shift arm workpieces have a downwardly protruding structure, and the inverted L-shaped structure of the positioning tooling effectively avoids the inability to fix the workpiece of this model due to structural conflicts during fixation; secondly, the overall structure of the drilling equipment is very compact, and each unit will have various different paths such as upward and downward during processing. The side of the positioning tooling is designed to be curved to effectively prevent the positioning tooling from colliding or interfering with other units on the frame during rotation, effectively ensuring the stability of each process.

[0016] Furthermore, the angle adjustment mechanism is located below the positioning tooling and includes a telescopic driving structure and a lifting head, and the end of the lifting head is arc-shaped.

[0017] Since space factors were taken into consideration during the research and development and design of this drilling equipment, the overall structure is very compact. There is no large space between the units on the frame and the rotating disk structure. In particular, the drilling unit needs to drill downwards. If the angle adjustment mechanism is arranged above the frame, although it can drive the tooling to rotate, it is easy to cause motion interference with the drilling unit, resulting in continuous and stable production. It is also easy to collide and damage the structure. Therefore, the angle adjustment mechanism is located below the positioning tooling and lifts the positioning tooling upward through the telescopic drive structure to rotate it in the vertical plane. This not only achieves the precision and accuracy of the rotation angle adjustment of the positioning tooling, but also avoids motion interference caused by crowded space among components above the frame, thereby ensuring the continuity and stability of each process and overall production.

[0018] Furthermore, the grinding drive structure includes a grinding cylinder and a longitudinal and transverse adjustment mechanism, the output shaft of the grinding cylinder moves horizontally and the end of the output shaft is connected and fixed to the longitudinal and transverse adjustment mechanism; the longitudinal and transverse adjustment mechanism includes a support seat, a fixed block is provided in the middle position of the support seat, and transverse sliding blocks with sliding connections are symmetrically provided on both sides of the fixed block; a through groove running through the width is opened in the outer end of the transverse sliding block, and a clamping block for clamping the grinding part is detachably installed in the through groove, the clamping block moves up and down in the through groove, and the clamping block is rotatably connected to the grinding part.

[0019] Furthermore, the grinding piece includes a grinding seat and a file. The grinding seat includes a clamping rod and a movable block. One end of the clamping rod extends into the clamping block, and the other end is bolted to the movable block. A floating spring is provided in the movable block. The file is located on the movable block and the bottom is connected to the floating spring. The file is a trapezoidal structure and its left and right ends gradually expand outward toward the bottom with the file surface as a reference.

[0020] When the applicant first designed the grinding unit, the structure he considered was to use a grinding head to grind the burrs on the workpiece. However, due to the compact structure of the drilling equipment and the very narrow space between the workpiece and the frame surface on the positioning fixture, the grinding head could not effectively operate to grind the surface. Therefore, considering the space factor, the applicant designed the grinding unit to perform lateral movement grinding, using a grinding cylinder to drive the grinding piece in and out along the lower surface of the workpiece, and using a longitudinal and lateral adjustment mechanism and a rotational connection between the grinding piece and the clamping block to achieve multi-degree-of-freedom adjustment of the grinding piece, so that the file surface of the file is parallel to the surface to be polished, thereby achieving effective grinding.

[0021] However, taking into account the differences in the fixed postures of different workpieces on the positioning tooling, there will be problems with inconsistent grinding quality when grinding workpieces even for workpieces of the same model and specification. Moreover, since the position and posture of the file is fixed during grinding, the distance between the file and the grinding surface will become larger and larger after the first pass through the grinding surface, and the grinding effect will be reduced. Therefore, in order to solve the above problem, the applicant has provided a floating spring between the file and the movable seat. The floating spring makes the file surface always close to the workpiece, and can also compensate for the error of the fixed posture, thereby ensuring that the grinding quality of all workpieces is good and consistent.

[0022] In addition, the file is detachably connected to the clamping rod through a movable seat, which facilitates quick and convenient replacement of worn files to ensure the grinding quality. The file has a trapezoidal structure and its left and right ends gradually expand toward the bottom with the file surface as a reference. One reason is to prevent the file from colliding with the workpiece when entering and exiting, and to ensure smooth entry and exit. Second, the file has a simple appearance and structure, and the file surface is short, so it can be linearly processed at one time without the need for additional machining processes, saving file processing costs.

[0023] Furthermore, a unloading head is installed between the output shaft end of the unloading cylinder and the positioning magnet, and an avoidance component is provided between the unloading head and the positioning magnet. The avoidance component includes an avoidance guide rod arranged for vertical sliding, the positioning magnet is fixed at the bottom of the avoidance guide rod, and a linear bearing is provided between the avoidance guide rod and the unloading head.

[0024] The avoidance assembly and the linear bearing make the space between the two positioning magnets adjustable, which is convenient for adapting to shift arms of various models and different thicknesses, and improving the versatility of the unloading unit. Moreover, the linear bearing avoids direct contact between the unloading head and the avoidance guide rod, reducing the friction loss between the components, while ensuring the avoidance response speed and automatic reset speed of the avoidance guide rod, ensuring continuous unloading.

[0025] Furthermore, a limiting unit is provided on the frame, which is located above the angle adjustment unit and is used to fix the upper surface of the workpiece, and the limiting unit includes a limiting block and a sliding base, the limiting block is fixed on the sliding base and is slidably connected to the frame through the sliding base.

[0026] When the drilling unit is drilling the shift arm workpiece, there is no fixing measure on the upper surface of the workpiece, which is prone to displacement or deviation of the workpiece due to machining vibration, resulting in reduced hole machining accuracy or even scrapping. Therefore, a limit unit is set on the frame to fix the shift arm from above, and cooperates with the positioning pin to achieve double fixation of the shift arm, effectively preventing unnecessary movement and vibration of the shift arm during high-speed drilling, improving drilling accuracy, ensuring that the position of each drilled hole meets the design requirements, and reducing the scrap rate. In addition, the limit unit is slidably connected to the frame so that it can adjust the position of different types of shift arm workpieces, ensuring that each type of workpiece can be effectively fixed, and enhancing the versatility of the equipment.

[0027] Furthermore, the positioning fixture is detachably connected with a movable seat between the two positioning holes, and the movable seat is provided with a fixing groove for accommodating the end of the workpiece.

[0028] The cooperation between the movable seat, the fixing groove and the positioning pin enables the positioning tool to be applicable to the clamping and fixing of most types of shift arms, thereby improving the versatility of the positioning tool.

[0029] Furthermore, a rolling bearing is provided on the lifting head, the axis of the rolling bearing is perpendicular to the movement direction of the lifting head, and the plane where the vertex of the rolling bearing is located is higher than the vertex plane of the lifting head.

[0030] The lifting head is in direct contact with the positioning fixture, and the friction between the two during the upward lifting process is sliding friction, and the loss of sliding friction is much greater than rolling friction. Therefore, by utilizing the fact that the plane where the apex of the rolling bearing is located is higher than the apex plane of the lifting head, the sliding friction between the lifting head and the positioning fixture is converted into rolling friction between the rolling bearing and the positioning fixture, effectively reducing friction loss and improving the response speed and service life of the structure.

[0031] Furthermore, the top of the positioning pin is conical.

[0032] The top of the locating pin is designed to be conical. One reason is to adapt to various types of shift arms and improve the versatility of the positioning tooling. The other reason is to reduce the positioning accuracy requirements between the workpiece and the positioning tooling. The conical design can increase the speed of workpiece clamping and thus improve processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following is further described in detail through specific implementation methods:

[0044] The reference numerals in the drawings of the specification include: shift arm 100, frame 200, loading station 300, pressing station 400, drilling station 500, grinding station 600, loosening station 700, unloading station 800, rotating disk structure 1, positioning unit 2, positioning tool 21, positioning hole 211, positioning pin 212, moving seat 213, fixing groove 214, threaded hole 215, pressing structure 22, rotating pressing cylinder 221, pressing block 222, drilling unit 3, drilling drive structure 31, drilling member 32, angle adjustment mechanism 4, lifting cylinder 41, lifting head 42, rolling bearing 43, limit unit 5, limit block 51, limit head 52, sliding Base 53, grinding unit 6, grinding cylinder 61, vertical and horizontal adjustment mechanism 62, support seat 621, fixed block 622, horizontal sliding block 623, adjusting bolt 624, clamping block 625, guide hole 626, fixing bolt 627, grinding piece 63, grinding seat 631, clamping rod 6311, movable seat 6312, floating spring 632, file 633, unloading unit 7, unloading lifting cylinder 71, unloading lifting head 72, unloading cylinder 73, unloading head 74, positioning magnet 75, avoidance component 8, avoidance guide rod 81, linear bearing 82, unloading hopper 9, pneumatic rotary joint 10, rotating slip ring 101, connecting plate 11, fixed seat 12, rotating shaft 13.

[0045] The embodiment is basically as shown in the attached Figure 1-Figure 10 As shown: an automatic drilling device compatible with multiple types of panels, including a rotating disk structure 1 and a drilling unit 3, a grinding unit 6 and a discharge unit 7 fixed on a frame 200; the rotating disk structure 1 realizes indexing rotation and positioning through existing technical structures, such as a dividing disk, a cam divider and an electric turntable, etc., which will not be repeated here; the rotating disk structure 1 is provided with a plurality of positioning units 2 for fixing the workpiece, and in this embodiment, six positioning units 2 are evenly arranged, correspondingly, as Figure 1 , Figure 2 As shown in the combination, six workstations are arranged on the frame 200, each of which is provided with a corresponding positioning unit 2. The six workstations are respectively a loading station 300, a pressing station 400, a drilling station 500, a grinding station 600, a loosening station 700 and an unloading station 800. The drilling unit 3 and the drilling station 500, the grinding unit 6 and the grinding station 600, and the unloading unit 7 and the unloading station 800 are arranged corresponding to each other.

[0046] like Figure 4 , Figure 5As shown in the combination, the positioning unit 2 includes a positioning tool 21 and a clamping structure 22. The rotating disk structure 1 is provided with a fixed seat 12 at each work station, and a rotating shaft 13 is provided on the fixed seat 12. The positioning tool 21 is rotatably connected to the fixed seat 12 through the rotating shaft 13 and rotates around the rotating shaft 13 in a vertical plane. In order to reduce rotational wear, a bearing is installed between the positioning tool 21 and the rotating shaft 13. The top surface of either end of the positioning fixture 21 protrudes upward and is higher than the top surface of the other end, making the positioning fixture 21 inverted L-shape, and the lateral part of the inverted L-shaped structure is a curved surface composed of multiple arcs on the outward side. Firstly, because some types of shift arm 100 workpieces have a downwardly protruding structure, the inverted L-shaped structure of the positioning fixture 21 effectively avoids the inability to fix this type of workpiece due to structural conflicts during fixation. Secondly, the overall structure of the drilling equipment is very compact, and each unit will have various different paths such as upward and downward during processing. The side of the positioning fixture 21 is designed to be curved to effectively prevent the positioning fixture 21 from colliding or interfering with other units on the frame 200 during rotation, thereby effectively ensuring the stable progress of each process.

[0047] like Figure 4 , Figure 5 As shown in combination, positioning holes 211 are opened at both ends of the positioning tool 21 and positioning pins 212 are installed, and the positioning holes 211 at either end are of a porous connected structure, so that different types of shift arm 100 workpieces can be adapted by adjusting the distance between the two positioning pins 212; preferably, a threaded hole 215 is also opened between the two ends of the positioning tool 21, and a movable seat 213 is installed at the threaded hole 215 by bolts, and a fixing groove 214 matching the shape of the end of the shift arm 100 workpiece is opened on the upper surface of the movable seat 213, so that the types and styles of the shift arm 100 workpiece clamped on the positioning tool 21 are more numerous and more versatile.

[0048] like Figure 2 , Figure 3As shown, the clamping structure 22 is fixed on the turntable of the rotating disk structure 1, and the clamping structure 22 rotates synchronously with the rotating disk structure 1, and the clamping structure 22 can be pre-clamped or loosened at the previous station before rotating to the next station. For example, one of the clamping structures 22 releases the clamping fixation of the workpiece at the loosening station 700 in advance before rotating to the unloading station 800, thereby reducing the clamping time and improving the overall processing rhythm; Specifically, the clamping structure 22 includes a rotating clamping cylinder 221 and a clamping block 222, and the frame 22 at the middle position of the rotating disk structure 1 00 is installed with a pneumatic rotary joint 10, and a plurality of docking air holes are arranged on the rotating slip ring 101 of the pneumatic rotary joint 10, each docking air hole comprises an air inlet and an air outlet, and each rotary clamping cylinder 221 is connected with a pair of docking air holes on the rotary slip ring 101 through a conduit, and the rotary slip ring 101 is fixed to the turntable of the rotary disk structure 1 through a connecting plate 11, so that the rotary slip ring 101 rotates synchronously with the rotary disk structure 1 to avoid entanglement and knotting of the conduit thereon; wherein the rotary clamping cylinder 221 and the pneumatic rotary joint 10 are both prior arts and will not be described in detail here.

[0049] like Figure 3 As shown, the drilling unit 3 includes a drilling drive structure 31 and a drilling member 32. The drilling drive structure 31 is a three-axis adjustment unit, including an X-axis adjustment screw, a Y-axis adjustment screw and a Z-axis adjustment screw. A drilling motor is fixed on the Z-axis adjustment screw. The drilling motor is connected to the drilling member 32, so that the drilling member 32 can be adjusted in three spaces of X, Y and Z axes according to the actual drilling position. The drilling member 32 includes a drilling seat and a drill bit, and the drill bit can be replaced according to the actual drilling size.

[0050] The frame 200 is also provided with an angle adjustment mechanism 4 that cooperates with the drilling unit 3. The angle adjustment mechanism 4 is used to adjust the rotation angle of the positioning tool 21. Figure 6 , Figure 7 As shown in the figure, the angle adjustment mechanism 4 is arranged below the positioning fixture 21 to avoid movement interference with other structures above the frame 200. The angle adjustment mechanism 4 includes a telescopic drive structure and a lifting head 42. The telescopic drive structure is a cylinder or an electric telescopic rod, etc. In this embodiment, the telescopic drive structure is a lifting cylinder 41, and the lifting head 42 is fixed to the end of the output shaft of the lifting cylinder 41. The end of the lifting head 42 is designed to be an arc shape, and a rolling bearing 43 is installed on the lifting head 42. The axis of the rolling bearing 43 is perpendicular to the movement direction of the lifting head 42, and the plane where the vertex of the rolling bearing 43 is located is higher than the vertex plane of the lifting head 42. In this way, the sliding friction between the lifting head 42 and the positioning fixture 21 is converted into the rolling friction between the first rolling bearing 43 and the positioning fixture 21, thereby reducing friction loss and improving the response speed and service life of the mechanism.

[0051] like Figure 6As shown, preferably, a limit unit 5 is also provided on the frame 200, which is located above the angle adjustment unit and is used to fix the upper surface of the workpiece. The limit unit 5 includes a limit block 51 and a sliding base 53. A limit head 52 is installed on the top of the limit block 51, and the bottom of the limit block 51 is fixed on the sliding base 53 and is slidably connected to the frame 200 through the sliding base 53; this can meet the top fixation of workpieces of different models, prevent unnecessary movement and vibration of the shift arm 100 during high-speed drilling, and help improve the accuracy of drilling.

[0052] The above-mentioned arrangement realizes the automated drilling processing of most types of shift arm 100 workpieces with unified clamping, and with the cooperation of the angle adjustment mechanism 4 and the limit unit 5, the drilling surfaces of different types of workpieces always remain horizontal and fixed during the drilling processing, and no vibration displacement or tilt will occur during the high-speed drilling process, effectively ensuring the drilling accuracy and quality of all workpieces, improving processing efficiency and reducing scrap rate.

[0053] The applicant considered the structure of using an electric or start-up grinding head to grind the burrs of the workpiece at the beginning of the design of the grinding unit 6. However, due to the compact structure of the drilling equipment and the very narrow space between the workpiece and the surface of the frame 200 on the positioning fixture 21, the grinding head cannot effectively operate to grind the surface, and the grinding quality is difficult to ensure; therefore, considering the space factor, the applicant designed the grinding unit 6 to perform lateral movement grinding; therefore, in order to solve the above problems, the applicant designed the following grinding unit 6:

[0054] like Figure 8 , Fig. 9As shown in the combination, the grinding unit 6 includes a grinding drive structure and a grinding piece 63, and is fixed on the frame 200 through a support plate. The grinding drive structure is a three-axis adjustment structure, including a grinding cylinder 61 and a longitudinal and transverse adjustment mechanism 62. The longitudinal and transverse adjustment mechanism 62 includes a support seat 621, and the support seat 621 slides on the support plate through a slide rail and is connected to the output shaft end of the grinding cylinder 61. The support seat 621 is provided with a fixed block 622 in the middle thereof and sliding grooves are symmetrically provided on both sides of the fixed block 622. Both sliding grooves are slidably connected with a transverse sliding block 623. The fixed block 622 is provided with two bolt through holes, and is threadedly connected with an adjusting bolt 624. The adjusting bolt 62 4 passes through the fixed block 622 and the end is fixed on the horizontal sliding block 623; the horizontal sliding block 623 has a through groove with a vertical slide groove at one end thereof, and a clamping block 625 for clamping the grinding piece 63 is installed in the through groove; the horizontal sliding block 623 is threadedly connected with an adjusting bolt 624 at the bottom of the through hole, and the adjusting bolt 624 moves up and down to drive the clamping block 625 to move longitudinally in the through hole; the horizontal sliding block 623 has guide holes 626 on the upper surface and the side surface thereof, and fixing bolts 627 are installed in the guide holes 626, and the fixing bolts 627 are used to fix the positions of the horizontal sliding block 623 and the clamping block 625 to prevent loosening during the grinding process and affect the grinding quality.

[0055] Since different workpieces have different fixed postures on the positioning fixture 21, the workpieces may have different grinding quality even if they are of the same model and specification. Moreover, since the position and posture of the file 633 are fixed during grinding, the distance between the file 633 and the grinding surface will become larger and larger after the first pass, and the grinding effect will be reduced. Therefore, the applicant designed the following grinding piece 63:

[0056] The grinding member 63 includes a grinding seat 631 and a file 633. The grinding seat 631 includes a clamping rod 6311 and a movable seat 6312. One end of the clamping rod 6311 is rotatably connected to the clamp block 625, and the other end is bolted to the movable seat 6312. A floating spring 632 is installed inside the movable seat 6312. The bottom of the file 633 is installed in the movable seat 6312 and the elastic force of the floating spring 632 makes the file 633 bounce upward, so that the file 633 can float up and down. The file 633 is a trapezoidal structure and its left and right ends gradually expand outward toward the bottom based on the file surface. The floating spring 632 makes the file 633 surface of the file 633 always close to the grinding surface of the workpiece, thereby enhancing the grinding effect. Through the above-mentioned setting, the grinding member 63 can be adjusted in the three spaces of the X, Y, and Z axes, so that the grinding member 63 changes its tilt state and is parallel to the grinding surface, ensuring that different types of workpieces can be effectively polished.

[0057] like Fig.10As shown, the unloading unit 7 includes a unloading lifting cylinder 71 and a unloading cylinder 73. The unloading lifting cylinder 71 is fixed on the frame 200, and the unloading cylinder 73 is fixed on the unloading hopper 9. The movement paths of the two are perpendicular to each other, and the ends of the output shafts of the two are respectively connected with a unloading lifting head 72 and a unloading head 74. The ends of the unloading lifting head 72 and the unloading head 74 are both equipped with positioning magnets 75, and the positioning magnets 75 are electromagnets. This not only ensures that the shift arm 100 can stably adsorb and unload the workpiece, but also simplifies the structure of the unloading unit 7 and reduces the manufacturing and maintenance costs.

[0058] like Fig.10 As shown, an avoidance component 8 is provided between the discharge head 74 and the positioning magnet 75 thereon. The avoidance component 8 includes a vertically sliding avoidance guide rod 81. A linear bearing 82 is provided between the avoidance guide rod 81 and the discharge head 74, so as to meet the unloading requirements of workpieces of different thicknesses.

[0059] The specific implementation process is as follows:

[0060] In this implementation process, the Figure 4 The specific process of the drilling equipment is described in detail by taking a certain type of shift arm 100 workpiece as an example. A large and a small round hole are opened at both ends of the shift arm 100, and the two round holes correspond to the positioning pins 212 on the positioning tool 21.

[0061] During specific operation, the stamped shift arm 100 workpiece is fixed to the positioning fixture 21 at the loading station 300 by the positioning pin 212, and then the rotating disk structure 1 is started. In this implementation process, the rotating disk structure 1 is a dividing disk, which rotates counterclockwise and each rotation angle is 60°. The positioning fixture 21 and the workpiece thereon are rotated to the clamping station 400. At this time, the pneumatic rotary joint 10 is started and controls the clamping structure 22 at the positioning fixture 21, so that the clamping block 222 is rotated 90° under the action of the rotary clamping cylinder 221 and moves downward to be pressed to the upper surface of the workpiece, so that the workpiece is stably fixed on the positioning fixture 21, and then before rotating to the drilling station 500, the rotary clamping cylinder 221 is controlled by the pneumatic rotary joint 10. The pressing block 222 is driven to move upward and rotate to reset, releasing the clamping fixation on the workpiece; then the workpiece is driven by the rotating disk structure 1 to rotate to the drilling station 500, and the lifting cylinder 41 in the angle adjustment mechanism 4 is started, driving the lifting head 42 to move upward to lift the positioning tool 21, so that the positioning tool 21 rotates around the rotating shaft 13 until the drilling surface of the shift arm 100 is horizontal and the upper surface of the workpiece is tightly against the limit head 52, and then the drilling member 32 is driven by the drilling motor to drill the workpiece. After the drilling is completed, the lifting cylinder 41 is reset downward, and the positioning tool 21 is rotated and reset to the fixed seat 12 under the action of gravity; the indexing disk rotates again to rotate the workpiece to the grinding station 600, and at this time, the rotating pressing cylinder 221 drives The clamping block 222 rotates down to clamp and fix the tooling, and the grinding cylinder 61 is started. Under the drive of the grinding cylinder 61, the file 633 of the grinding piece 63 grinds the burrs on the bottom surface opposite to the drilling surface; after the grinding is completed, the workpiece is driven by the dividing plate to rotate to the loosening station 700. At this time, the rotating clamping cylinder 221 is controlled by the pneumatic rotary joint 10 to drive the clamping block 222 to move upward and rotate to reset, thereby releasing the clamping and fixing of the workpiece; the dividing plate rotates again so that the workpiece is located at the unloading station 800, and the unloading lifting cylinder 71 and the unloading cylinder 73 at the unloading station 800 are started so that the unloading lifting head 72 and the unloading head 74 are respectively located on the upper and lower sides of the workpiece, and the positioning magnets 75 on both are energized, and the unloading lifting cylinder 71 moves upward The movement causes the positioning magnet 75 to be adsorbed under the workpiece to prevent the workpiece from shaking during the lifting process, and continues to lift the workpiece upward so that it contacts the positioning magnet 75 on the discharge head 74. The positioning magnet 75 on the discharge head 74 adsorbs the upper surface of the workpiece, and at the same time, the positioning magnet 75 on the unloading lifting head 72 is powered off, releasing the adsorption of the lower surface of the workpiece. Then, the unloading cylinder 73 is reset to drive the workpiece to move horizontally toward the unloading hopper 9. When the workpiece is above the entrance of the unloading hopper 9, the positioning magnet 75 on the unloading head 74 is powered off, and the workpiece falls into the unloading hopper 9 and is transferred along the inclined hopper surface for collection, completing the unloading of the workpiece. The above is the completion of the drilling process of a single workpiece on the drilling equipment; repeat the above operation process to achieve continuous processing of the workpiece.
