Due to its high precision, high efficiency, and high load capacity, it is widely used in various automation equipment, robots, precision measuring equipment and other fields.

[0003] The base of the linear module is an important part of it. The base bears the structure and weight of the entire module and provides stable support for it. The repeatability of the linear module depends largely on the processing accuracy of the base. The base is generally equipped with at least a number of high-precision machined reference surfaces, including at least the positioning reference surface at the bottom, the side reference surface on the side of the base, and two installation reference surfaces in the base for installing the slide rails.

[0004] In the existing production process of the base, the clamping accuracy cannot be guaranteed after the operator loads the base profile blank to the processing equipment, and manual tool setting is required before processing, which requires high accuracy of the operator's operation and high personnel costs. Especially after the base reference surface is processed, it is used as a reference to process other reference surfaces, which requires high processing accuracy.

[0023] Reference Figures 1 to 5 The profile processing positioning clamping device of the present invention is implemented as follows: like Figure 1 As shown, a profile processing positioning and clamping device includes: a positioning base 100, a loading platform 200, a clamping mechanism 300 and a material moving mechanism 400.

[0024] The upper end of the positioning base 100 is provided with a processing positioning groove 110. The upper end of the loading platform 200 is provided with a loading groove 210. The positioning base 100 and the loading platform 200 are arranged front and back, and the loading groove 210 is arranged behind the processing positioning groove 110.

[0025] The clamping mechanism 300 includes: a clamping frame 310, a left clamp 320, a right clamp 330 and a clamping driving member 340. The left clamp 320 and the right clamp 330 are both arranged at the rear side of the clamping frame 310. The left clamp 320 and the right clamp 330 are arranged on the left and right sides, and the left clamp 320 and the right clamp 330 are provided with clamping parts on the opposite sides. The clamping parts are used to clamp external processing materials. The clamping driving member 340 is configured to drive the left clamp 320 and / or the right clamp 330 to move, so that the two clamping parts can move closer to each other or away from each other, so as to clamp or release the processing materials.

[0026] The front side of the positioning base 100 and the front side of the loading platform 200 are both provided with an escape space that can accommodate the clamping rack 310. When the clamping rack 310 is in the escape space in front of the positioning base 100, the two clamping parts are arranged on the left and right sides of the processing positioning groove 110. When the clamping rack 310 is in the escape space in front of the loading platform 200, the two clamping parts are arranged on the left and right sides of the loading groove 210.

[0027] The material moving mechanism 400 is configured to drive the material clamping mechanism 300 to move, so that the material clamping frame 310 moves to the two avoidance spaces, and the clamping part moves between the processing positioning groove 110 and the loading groove 210 .

[0028] In actual use, the material moving mechanism 400 drives the clamping mechanism 300 to move between the two avoidance spaces, so that the clamping mechanism 300 can reach the loading slot 210 and the processing positioning slot 110 in sequence. The clamping driving member 340 can drive the two clamping parts of the left clamp 320 and the right clamp 330 to clamp the material tightly. The material moving mechanism 400 cooperates with the clamping driving member 340 to achieve the clamping and transportation of the processed material. The left clamp 320 and the right clamp 330 in the clamping mechanism 300 are connected to the clamping frame 310 at one end, and the clamping part is low, so that the left clamp 320 and the right clamp 330 can avoid collision and interference with the loading platform 200 or the positioning base 100. The left clamp 320 and the right clamp 330 arranged on the left and right sides can avoid the upper side space of the processed material. After the material is transported to the processing positioning slot 110, the clamping mechanism 300 can keep the material clamped, which is convenient for processing the material. The profile processing positioning and clamping device of the present invention can realize automatic clamping, carrying and loading of processing materials, thereby improving production efficiency; the processing materials can be positioned at the loading position and the processing position through the groove structure to avoid repeated tool alignment; during the processing, the left clamp 320 and the right clamp 330 can maintain clamping of the material, thereby improving processing accuracy.

[0029] In this embodiment, the processing positioning groove 110 has a first positioning surface perpendicular to the up and down direction. When in use, the linear module base is placed in the processing positioning groove 110, and the reference surface at the lower end of the base can fit the first positioning surface, thereby improving the flatness of the processing and reducing the parallelism error between the processing end surface and the reference surface at the lower end of the base. A second positioning surface is provided at the front end of the first positioning surface. The second positioning surface is perpendicular to the front and rear directions and extends in the left and right directions. During the processing, the side reference surface of the linear module base can be pressed against the second positioning surface, and the first positioning surface and the second positioning surface can provide positioning references for the processing material on the processing positioning groove 110, thereby realizing high-precision processing.

[0030] Furthermore, a clamping mechanism 120 for pressing the base to be processed forward against the second positioning surface is provided at the rear side of the processing positioning groove 110 .

[0031] The edge clamping mechanism 120 includes: an eccentric positioning column 121 and an edge driving component 122. The eccentric positioning column 121 is rotatably arranged at the rear side of the processed positioning groove 110. The eccentric positioning column 121 has an eccentrically arranged eccentric positioning portion 1211. The edge driving component 122 is used to drive the eccentric positioning column 121 to rotate.

[0032] The eccentric positioning column 121 realizes the clamping and fixing of the material through the eccentrically rotating eccentric positioning part 1211. In this embodiment, the eccentric positioning part 1211 is in the shape of a cylinder, the rotation axis of the eccentric positioning column 121 extends in the up-down direction, and the axis of the eccentric positioning part 1211 is parallel to the rotation axis of the eccentric positioning column 121 and is eccentrically arranged. When the side driving component 122 drives the eccentric positioning column 121 to rotate, the distance between the outer edge of the eccentric positioning part 1211 and the second positioning surface changes, thereby realizing the side clamping of the material.

[0033] In actual use, the distance between the rotation axis of the eccentric positioning column 121 and the second positioning surface is set according to the width dimension of the clamping position of the processed material in the front-to-back direction, the eccentric spacing and the outer radius of the eccentric positioning part 1211. Specifically: the difference between the outer radius and the eccentric spacing of the eccentric positioning part 1211 is D1, the sum of the outer radius and the eccentric spacing of the eccentric positioning part 1211 is D2, the distance between the rotation axis of the eccentric positioning column 121 and the second positioning surface is L1, and the width dimension of the clamping position of the processed material in the front-to-back direction is L2, satisfying L1-D2<L2<L1-D1.

[0034] In this embodiment, the first positioning surface is the upper end surface of the positioning base 100, and a positioning strip 111 is provided on the upper front side of the positioning base 100. The positioning strip 111 is in the shape of a long strip extending in the left-right direction, and the cross section of the positioning strip 111 is rectangular. The second positioning surface is the rear end surface of the positioning strip 111. Furthermore, in order to adapt to the processing of linear module bases of different specifications, the positioning strip 111 is adjustable and installed on the upper front side of the positioning base 100 along the front-back direction.

[0035] The left clamp 320 and the right clamp 330 are both provided with a clearance portion, and the clearance portion is provided at the front side of the clamping portion. When the clamping portion is located on the processing positioning groove 110, the clearance portion avoids the position of the positioning bar 111 to avoid interference and collision.

[0036] In this embodiment, the positioning bar 111 is provided with a strip hole extending forward and backward, and the positioning bar 111 is fixed by screws passing through the strip hole and locked to the positioning base 100. The upper front end of the positioning base 100 is provided with a plurality of adjustment screws extending forward and backward, the adjustment screws are rotatably connected to the positioning base 100 and are threadedly connected to the positioning bar 111, and after loosening the fixed screws, the position of the positioning bar 111 is adjusted by rotating the adjustment screws and then locked to achieve adjustable installation of the positioning bar 111, so that the installation position of the positioning bar 111 can adapt to the processing of materials of different specifications.

[0037] In some embodiments, to ensure accuracy, the positioning bar 111 and the positioning base 100 are integrally formed, and the positioning base 100 can be replaced to adapt to materials of different specifications.

[0038] The base of the linear module is generally longer in length. When the base to be processed is set in the processing positioning groove 110, its length direction extends in the left-right direction. In order to enable the base to be clamped and positioned at all locations, the number of the eccentric positioning columns 121 is multiple, and the multiple eccentric positioning columns 121 are arranged in the left-right direction.

[0039] The side drive component 122 includes: a side clamping drive motor, a transmission assembly, and a plurality of drive shafts 1221. The number of the drive shafts 1221 is consistent with the number of the eccentric positioning columns 121. The drive shafts 1221 are coaxially connected to the eccentric positioning columns 121 in a one-to-one correspondence. The side clamping drive motor is transmission-connected to the plurality of drive shafts 1221 through the transmission assembly, so that the plurality of drive shafts 1221 rotate synchronously.

[0040] In this embodiment, the transmission assembly adopts a worm gear structure, and the transmission assembly includes a transmission worm 1222 and a transmission worm wheel 1223. The transmission worm wheel 1223 is coaxially fixedly connected to the drive shaft 1221 in a one-to-one correspondence, and the transmission worm 1222 extends in the left and right directions and is in transmission engagement with the transmission worm wheel 1223. The output shaft of the side clamping drive motor is fixedly connected to the transmission worm 1222. When the side clamping drive motor drives the transmission worm 1222 to rotate, multiple transmission worm wheels 1223 rotate synchronously, thereby driving multiple drive shafts 1221 to rotate, and realizing synchronous driving of the eccentric positioning column 121.

[0041] In order to avoid the poor rotation synchronization of multiple eccentric positioning columns 121 caused by the meshing clearance of the transmission component, a torque limiter 1224 is provided between the drive shaft 1221 and the eccentric positioning column 121 of this embodiment, and the axial ends of the torque limiter 1224 are coaxially fixedly connected with the drive shaft 1221 and the eccentric positioning column 121 respectively. The torque limiter 1224 is a mechanical overload protection device, which is often installed between the drive side and the load side of the power transmission. Once an overload occurs, the transmission torque exceeds the set value, and it will be disengaged or slipped, so that the active and passive sides of the power transmission are separated, so that the mechanical equipment is protected from damage caused by overload. The torque limiter 1224 in this embodiment is a unidirectional torque limiter 1224. The torque limiter 1224 has the advantages of adjustable overload torque, providing an overload electrical signal at the moment of overload, high torque accuracy, and sensitive response. When the multiple drive shafts 1221 of the transmission assembly rotate, the torque limiter 1224 drives the eccentric positioning column 121 to rotate, so that the eccentric positioning portion 1211 is pressed against the rear end of the material, thereby clamping the material between the eccentric positioning portion 1211 and the second positioning surface. After that, the drive shaft 1221 continues to rotate, and the eccentric positioning column 121 is subjected to clamping resistance and resists the rotation torque. At this time, the torque limiter 1224 is overloaded. The drive shaft 1221 and the eccentric positioning column 121 are connected by the torque limiter 1224, which greatly reduces the processing error or installation error of the eccentric positioning column 121, and ensures that the clamping force of each eccentric positioning column 121 on the material will not have too much deviation.

[0042] In order to prevent machining debris and cutting fluid from affecting the edge driving member 122, the positioning base 100 of this embodiment has a hollow inner cavity 130, and the inner cavity 130 is arranged below the machining positioning groove 110. The edge driving member 122 is arranged in the inner cavity 130. The eccentric positioning column 121 is rotatably penetrated in the positioning base 100, and the upper and lower ends of the eccentric positioning column 121 are respectively arranged in the machining positioning groove 110 and the inner cavity 130.

[0043] Furthermore, a maintenance window 131 communicating with the inner cavity 130 is provided at the rear side of the positioning base 100. The side driving member 122 is aligned front and rear with the maintenance window 131. The maintenance window 131 is provided with a detachable baffle 132 to prevent foreign matter from entering the inner cavity 130 and affecting the side driving member 122.

[0044] In some other embodiments, for the convenience of adjustment and installation, a clamping seat is provided at the rear side of the positioning base 100, and the clamping seat is detachably mounted on the rear side of the positioning base 100. The side driving member 122 and the eccentric positioning column 121 are both mounted on the clamping seat.

[0045] The material moving mechanism 400 of this embodiment includes: a lifting drive member 420 and a material moving drive member 430. The lifting drive member 420 is configured to drive the material clamping frame 310 to move up and down, and the material moving drive member 430 is configured to drive the material clamping frame 310 to move forward and backward. The lifting drive member 420 and the material moving drive member 430 are used to move the material clamping frame 310 to the two avoidance spaces, and the material clamping mechanism 300 is moved between the processing positioning groove 110 and the loading groove 210.

[0046] Specifically, the material moving mechanism 400 further includes a material moving seat 410, the material moving seat 410 is slidably arranged in the front-to-back direction, and the material clamping frame 310 is slidably installed in the up-down direction on the material moving seat 410. The material moving driving component 430 is used to drive the material moving seat 410 to move forward and backward relative to the positioning base 100 and the loading platform 200, and the lifting driving component 420 is used to drive the material clamping frame 310 to move up and down relative to the material moving seat 410.

[0047] See attached Figure 3 The material transfer seats 410 are arranged in pairs on the left and right sides of the positioning base 100 and the loading platform 200, and the material transfer seats 410 are slidably arranged through linear slide rails extending forward and backward. The material transfer drive component 430 adopts a screw nut drive assembly arranged along the front and back. The material transfer seat 410 is fixedly provided with lifting guide columns extending up and down, and the left and right ends of the clamping frame 310 are respectively slidably sleeved on the lifting guide columns. The lifting drive component 420 adopts a cylinder arranged in the up and down direction.

[0048] Furthermore, the first positioning surface is preferably higher than the loading slot 210. When the lifting drive member 420 drives the clamping frame 310 to press downward, the processed material clamped by the clamping mechanism 300 can be pressed downward against the first positioning surface to avoid leaving a gap, thereby improving processing accuracy.

[0049] In some other embodiments, the lifting drive component 420 and the material moving drive component 430 can adopt linear drive components such as cylinders, electric push rods, hydraulic push rods or screw nut drive assemblies according to needs.

[0050] In a further embodiment, the clamping mechanism 300 is disposed at the rear of the material transfer seat 410, and the front of the material transfer seat 410 is provided with a cleaning mechanism 500 for cleaning the positioning base 100. When the clamping frame 310 is in the avoidance space in front of the loading platform 200, the cleaning mechanism 500 is located above the processing positioning groove 110.

[0051] The cleaning mechanism 500 of this embodiment includes: a brushing component 510 and a brushing driving component 520 for driving the brushing component 510 to move left and right. A cleaning brush is provided at the lower end of the brushing component 510, and a brush moving cylinder is provided at the upper end of the brushing component 510 for driving the cleaning brush to move up and down. In actual use, the brushing driving component 520 drives the brushing component 510 to move, and the cleaning brush that is pressed downward is used to clean the processing positioning groove 110 to prevent processing debris from affecting positioning. The brushing driving component 520 can adopt a linear driving component such as a cylinder, an electric push rod, a hydraulic push rod, or a screw nut driving assembly arranged in the left and right directions.

[0052] In this embodiment, one of the left clamp 320 and the right clamp 330 is fixedly connected to the clamping frame 310, and the clamping driving component 340 is used to drive the other of the left clamp 320 and the right clamp 330 to move along the left and right directions to achieve a clamping action.

[0053] See attached Figure 2 The front end of the left clamp 320 is fixedly connected to the clamp frame 310, the front end of the right clamp 330 is slidably connected to the clamp frame 310 in the left-right direction, and the clamp driving member 340 has a clamp driving end that is transmission-connected to the right clamp 330 and enables the right clamp 330 to move left and right relative to the left clamp 320. In order to enable the left clamp 320 and the right clamp 330 to maintain a clamping force toward each other during the clamping process, the clamp driving member 340 uses a cylinder arranged along the left and right sides. In actual use, the right clamp 330 can be clamped to the left under the action of the clamp driving member 340, so that the material can be pressed against the clamping part of the left clamp 320, thereby improving the repeat positioning accuracy.

[0054] Furthermore, in order to process materials of different lengths, the clamping driving member 340 is adjustable in the left and right directions, so that the action stroke position of the right clamping member 330 can be adjusted left and right. Figure 2 and 3 The rear side of the clamping frame 310 is provided with an adjustment seat 311 and an adjustment driving member 312. The piston rod end of the clamping driving member 340 is connected to the right clamp 330 by transmission, and the cylinder of the clamping driving member 340 is connected to the adjustment seat 311. The adjustment driving member 312 includes an adjustment screw extending left and right, the adjustment screw is rotatably connected to the clamping frame 310, and the adjustment seat 311 is connected to the adjustment screw by thread transmission. When the adjustment screw is rotated, the adjustment seat 311 moves left and right under the action of the thread transmission, thereby adjusting the position of the clamping driving member 340, so that the action area of ​​the right clamp 330 can be set according to the length of the material, thereby improving flexibility and adaptability.

[0055] The adjusting drive component 312 also includes an adjusting shaft, which extends in the up-down direction and is rotatably connected to the clamping frame 310. The adjusting shaft and the adjusting screw are synchronously driven via a helical gear or a worm gear structure, and a hand wheel or a driving motor is provided at the upper end of the adjusting shaft.

[0056] In some other embodiments, the left clamping member 320 and the right clamping member 330 are both slidably connected to the clamping frame 310 along the left-right direction.

[0057] The material clamping driving member 340 includes a left material clamping driving unit and a right material clamping driving unit, wherein the left material clamping driving unit is used to drive the left clamping member 320 to move left and right, and the right material clamping driving unit is used to drive the right clamping member 330 to move left and right. Specifically, the front ends of the left clamping member 320 and the right clamping member 330 are both connected to the rear side of the material clamping frame 310 in a sliding manner in the left and right directions.

[0058] The left material clamping drive unit and the right material clamping drive unit can be linear drive components such as cylinders, electric push rods, hydraulic push rods or screw nut drive components. The left clamp 320 and the right clamp 330 are driven to move in the left and right directions respectively by the left material clamping drive unit and the right material clamping drive unit.

[0059] In some embodiments, the clamping drive member 340 may be a double-threaded screw extending in the left-right direction, and the reverse threads may be used to drive the left clamp 320 and the right clamp 330 to move respectively, so that the left clamp 320 and the right clamp 330 can be synchronously moved toward each other or synchronously moved away from each other, thereby achieving center clamping. In other embodiments, the clamping drive member 340 may be driven by synchronous belt drive, chain drive, gear drive, worm gear drive or other transmission methods to achieve center clamping of the left clamp 320 and the right clamp 330.

[0060] Since the finishing surfaces of the linear module base are generally distributed on the upper and lower sides, in order to avoid repeated loading and reduce production efficiency, the left clamp 320 and the right clamp 330 in this embodiment are both provided with a rotating clamp block 350, and the clamping portion is arranged on the opposite side of the rotating clamp block 350, and the clamping mechanism 300 also includes a rotating drive component 360 for driving the rotating clamp block 350 to rotate.

[0061] In actual use, the left clamp 320 and the right clamp 330 clamp the left and right ends of the material through two rotating clamping blocks 350. After processing the high-precision surface at the bottom of the material, the rotating driving component 360 drives the rotating clamping block 350 to rotate, so that the material can be turned over, thereby processing the high-precision surface on the top. The processing of multiple positions of the material can be completed in one loading, avoiding repeated loading and improving production efficiency.

[0062] In this embodiment, the rotation driving member 360 is two rotating cylinders respectively provided on the left clamp 320 and the right clamp 330. The rotating cylinder and the rotating clamp block 350 are respectively provided on the left and right sides of the rear end of the left clamp 320, and another rotating clamp block 350 and another rotating cylinder are respectively provided on the left and right sides of the right clamp 330. One end of the rotating clamp block 350 is rotatably provided in the left clamp 320 or the right clamp 330 and is connected to the rotation driving member 360.

[0063] In order to enable the two rotating clamps 350 to rotate synchronously and avoid material deviation, a linkage guide column 370 and a linkage sleeve 380 are provided between the two rotating clamps 350. The linkage guide column 370 and the linkage sleeve 380 are respectively fixedly connected to the two rotating clamps 350, and the linkage guide column 370 and the linkage sleeve 380 are coaxially sleeved with each other.

[0064] In particular, the distance between the axis of the linkage guide column 370 and the linkage sleeve 380 and the rotation axis of the rotating clamp block 350 needs to be set according to the front-to-back width of the loading groove 210 and the processing positioning groove 110 to avoid interference and collision with the loading platform 200 and the positioning base 100. The rotating clamp block 350 is provided with a corner for avoiding the positioning bar 111.

[0065] In other embodiments, the rotation drive member 360 may also be a rotation drive element such as a servo motor, a stepper motor or a pneumatic motor. In some other embodiments, one of the left clamp 320 or the right clamp 330 is provided with a rotation drive member 360, and the two rotation clamping blocks 350 of the left clamp 320 and the right clamp 330 are respectively rotated synchronously through the linkage guide column 370 and the linkage sleeve 380.

[0066] Different specifications of linear module bases often have different cross-sectional shapes. To improve adaptability, in this embodiment, the clamping parts of the left clamp 320 and the right clamp 330 are both in the shape of rectangular blocks. The clamping part can be detachably provided with a positioning clamping column, which extends in the left and right directions, and the end of the positioning clamping column is detachably connected to the rotating clamp block 350. In actual use, the outer contour of the end of the material is positioned by the positioning clamping column, so that the material is stable during the clamping process.

[0067] When using the profile processing positioning clamping device of the present invention: first, the position of the adjustment seat 311 is adjusted by adjusting the driving member 312 so that the distance between the right clamp 330 and the left clamp 320 can adapt to the length size specification of the base to be processed.

[0068] Then, the base material to be processed is placed on the loading trough 210 of the loading platform 200. Next, the lifting drive component 420 drives the clamping frame 310 to rise to the upper limit position, and the material moving drive component 430 drives the material moving seat 410 to move backward, so that the clamping frame 310 moves to the top of the loading trough 210. At this time, the lifting drive component 420 drives the clamping frame 310 to move downward, so that the two clamping parts of the left clamp 320 and the right clamp 330 are respectively located on the left and right sides of the base to be processed. At this time, the clamping drive component 340 drives the right clamp 330 to move to the left, and the left and right ends of the base are clamped by the two clamping parts of the left clamp 320 and the right clamp 330.

[0069] Afterwards, the lifting drive member 420 and the material transfer drive member 430 are operated in sequence, so that the clamping mechanism 300 drives the clamped base material to move forward to the top of the processing positioning groove 110. Since the base material is loaded into the loading groove 210 in an upright position, the bottom end of the base material faces downward. In the process of the material transfer mechanism 400 driving the clamping mechanism 300 to rise and move forward, the rotating drive member 360 drives the rotating clamp block 350 to rotate, so that the base material is turned 180 degrees.

[0070] Then, the clamping mechanism 300 moves downward to place the base material on the processing positioning groove 110, with the bottom surface of the base material facing upward, and the positioning reference surface of the base material and the edge reference surface of the bottom side are processed with high precision by milling processing equipment.

[0071] Afterwards, the material moving mechanism 400 drives the clamping mechanism 300 and the base material to rise up and flip 180 degrees again before putting it back into the processing positioning groove 110. At this time, the positioning reference surface at the bottom of the base material is in contact with the first positioning surface, and the side positioning surface is close to the second positioning surface.

[0072] At this time, the side driving member 122 drives the multiple driving shafts 1221 to rotate synchronously through the transmission action of the transmission worm 1222 and the transmission worm wheel 1223, so that the multiple eccentric positioning columns 121 rotate synchronously, and the rear side of the base material is pressed forward through the eccentric positioning part 1211, so that the side positioning surface of the base is pressed forward against the second positioning surface. After that, the remaining high-precision reference surfaces of the base material are processed by milling processing equipment.

[0073] After the processing is completed, the material moving mechanism 400 drives the material clamping mechanism 300 to move the base material and place it on the loading trough 210 to wait for the next processing.

[0074] At this time, the cleaning mechanism is located above the processing positioning groove 110. The brush moving cylinder drives the cleaning brush downward to press against the processing positioning groove 110, and the brush driving member 520 drives the brush member 510 to move left and right, and the processing positioning groove 110 is cleaned by the cleaning brush, thereby preventing the processing debris from affecting the next processing.
