Description

Technical Field

[0001] The utility model relates to the technical field of clamping feeding, in particular to a mobile feeding fixture. Background Art

[0002] The clamping feeding equipment is used in the process of conveying the workpiece. After clamping the workpiece, it is transported in a predetermined direction. It is usually used for conveying sheet and plate-shaped workpieces.

[0003] like Figure 1 As shown, a feeding jig on the market includes two clamps, wherein the first clamp 01 can move in a predetermined direction, and the second clamp 02 is fixedly arranged. On the feeding jig, in order to facilitate the assembly of the workpiece to be transported on the jig, the upper pressure arm 011 of the first clamp 01 and the second clamp 02 is arranged as a cantilever structure, so that the workpiece can be assembled into the clamp at the opening of the free end of the upper pressure arm 011. The upper pressing arm 011 is a cantilever structure, so when the lower pressing block moves upward to clamp the workpiece, the free end of the upper pressing arm 011 tilts upward under the pressure of the lower pressing block 012. At this time, when the workpiece is clamped by the upper pressing arm 011 and the lower pressing block 012, the clamping force between the free end of the upper pressing arm 011 and the lower pressing block 012 is reduced, and the clamping force of the workpiece to be transported at both ends of the upper pressing arm 011 is unbalanced. At this time, during the transportation of the workpiece, the workpiece to be transported will deviate, affecting the transportation accuracy. At the same time, the long-term operation of the jig causes the tilting amplitude of the upper pressing arm 011 to gradually increase, which will aggravate the deviation amplitude of the workpiece during transportation and seriously affect the service life of the jig.

DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0034] The utility model provides a mobile feeding fixture. By setting the clamp used for clamping the workpiece and dragging the workpiece to move as a gantry structure, the clamping force received by both sides of the workpiece can be balanced during the process of clamping the workpiece, avoiding the situation of deviation during transportation, and at the same time, avoiding the situation of warping and bending of the upper clamp 21, thereby ensuring the service life of the clamp.

[0035] Embodiment 1

[0036] In this embodiment, if Figures 2 - 5 As shown, a mobile feeding fixture provided in this embodiment includes a chassis 1, on which a mobile clamp 2 is movably arranged along a predetermined direction, the mobile clamp 2 includes an upper clamp 21 and a lower clamp block 22, and the chassis 1 is provided with a mobile driving device that is connected to the mobile clamp 2 to drive the mobile clamp 2 to reciprocate along the predetermined direction and a clamping driving device that is connected to the lower clamp block 22 to drive the lower clamp block 22 to reciprocate toward the upper clamp 21. The upper clamp 21 includes a crossbeam 211 and an upper clamping assembly 212, wherein the upper clamping assembly 212 includes an upper clamping member 213 and an adjusting mechanism 214, wherein Legs 2111 are formed at both ends of the crossbeam 211 to support the crossbeam 211, and the legs 2111 are transmission connected to the mobile driving device; an upper clamping assembly 212 is arranged on the crossbeam and is arranged corresponding to the lower clamping block to complete the clamping work together with the lower clamping block. Specifically, the upper clamping piece 213 is arranged corresponding to the lower clamping block 22; the adjusting mechanism 214 is installed on the crossbeam 211 and is transmission connected to the upper clamping piece 213 to drive the upper clamping piece 213 to reciprocate toward the direction of the lower clamping block to adjust the gap between the upper clamping piece 213 and the lower clamping block 22.

[0037] When clamping a workpiece, the crossbeam 211 of the upper chuck 21 is set as a gantry structure and supported by the legs 2111 at both ends. The upper clamping member 213 is in transmission connection with the adjusting device and is arranged above the crossbeam 211. When the lower clamping block 22 moves towards the upper clamping member 213 under the drive of the clamping drive device and clamps the workpiece, the crossbeam 211 can maintain balanced force under the support of the two legs 2111 and will not tilt. Therefore, during the clamping process of the workpiece, the clamping forces received at both ends of the workpiece are balanced with each other. Therefore, when clamping the workpiece, when the upper chuck 21 moves along a predetermined direction under the drive of the moving drive device to convey the workpiece, the conveyed workpiece will not deviate due to uneven force. At the same time, since the situation of the crossbeam 211 tilting during the clamping of the workpiece is avoided, the service performance and service life of the crossbeam 211 can be guaranteed.

[0038] In this embodiment, the clamping of the workpiece is achieved by the movement of the lower clamping block 22 towards the upper clamping member 213. In this embodiment, the stroke of the clamping drive device driving the lower clamping block 22 towards the upper clamping member 213 is fixed. Therefore, it can be ensured that during the continuous conveying of the workpiece, the continuous clamping force on the workpiece is the same. Therefore, in order to adapt to the conveying of workpieces with different thickness dimensions, the feeding jig provided in this embodiment is also configured with an adjusting mechanism 214 to adjust the position of the upper clamping member 213, thereby changing the distance from the lower clamping block 22, that is, being able to adapt to the clamping of workpieces with different thickness dimensions, so as to provide an appropriate clamping force to convey the workpiece. As Figure 4 shown, the adjusting mechanism 214 includes an adjusting member 2141 and a connecting member 2142. The adjusting member 2141 is rotatably connected to the crossbeam 211, and the connecting member 2142 is movably connected to the crossbeam 211 along the direction towards the lower clamping block 22. One end of the connecting member 2142 forms a thread pair with the adjusting member 2141, and the other end is fixedly connected to the upper clamping member 213.

[0039] When rotating the adjusting member 2141, through the threaded connection, the connecting member 2142 is driven to move linearly along the axial direction of the connecting member 2142 as the adjusting member 2141 rotates, so as to move the upper clamping member 213 towards or away from the lower clamping block 22, and then adjust the distance between the upper clamping member 213 and the lower clamping block 22 to adapt to workpieces with different thickness dimensions. It can be imagined that a guiding structure is provided between the connecting member 2142 and the crossbeam 211, and the guiding structure can be set as a guiding plane, a guiding groove or a guiding block, so that the connecting member 2142 can slide along the axis on the crossbeam 211 and will not rotate axially as the adjusting member 2141 rotates.

[0040] When the lower clamping block 22 and the upper clamping member 213 clamp the workpiece, a buffer structure is provided on the upper clamping member 213 to achieve buffering during the clamping of the workpiece to prevent the workpiece from being damaged due to excessive clamping force. Figure 5 As shown, the upper clamping member 213 includes a main body 2131, and clamping arms 2132 are formed at both ends of the main body 2131. One end of the clamping arm 2132 is formed on the main body 2131, and the other end extends toward the other end of the main body 2131, and at least one buffer groove 2133 with an open end is arranged between the clamping arm 2132 and the main body 2131.

[0041] In this embodiment, the clamping arm 2132 is configured as a C-shaped structure, and a buffer groove 2133 is provided in the middle of the clamping arm. The upper end of the clamping arm 2132 is formed at the end of the main body 2131, and a buffer groove 2133 is also formed between the clamping arm 2132 and the main body 2131. When the lower clamping block 22 moves toward the upper clamping member 213 and clamps the workpiece, when the clamping force of the lower clamping block 22 is too large, the buffer groove 2133 of the clamping arm 2132 is compressed, thereby causing elastic deformation, and elastically absorbing the clamping force of the lower clamping block 22, thereby preventing the workpiece from being crushed by excessive clamping force, thereby ensuring the performance of the workpiece.

[0042] At the same time, in this embodiment, a fixed clamp 3 having a structure substantially the same as that of the movable clamp 2 is also provided on the feeding jig. The fixed clamp 3 is fixedly provided on the chassis 1, and the lower clamp block 22 is transmission-connected to the clamping drive device, so that it can move toward the direction of the upper clamp 213 to transport the workpiece.

[0043] During the transportation of the workpiece, when the mobile clamp 2 clamps the workpiece and transports it in a predetermined direction under the drive of the mobile drive device, the fixed clamp 3 will relax the clamping action on the workpiece to facilitate the workpiece to pass through the fixed clamp 3 for transportation; when the mobile clamp 2 transports the workpiece for a distance equal to the maximum transportation stroke of the mobile clamp 2, the mobile clamp 2 needs to relax the workpiece and return it to the initial position under the drive of the mobile drive device. At this time, the lower clamp block 22 of the fixed clamp 3 moves toward the upper clamp 213 of the fixed clamp 3 under the drive of the clamping drive device, thereby clamping the workpiece in the fixed clamp 3 to prevent the workpiece from being brought back together during the retraction of the mobile clamp 2, or moving and affecting the transportation of the workpiece.

[0044] It can be imagined that in this embodiment, the moving drive device and the clamping drive device can be implemented by any one of the existing technologies, which can realize the movement of the mobile clamp 2 along a predetermined direction and the movement of the lower clamping block 22 toward the upper clamping member 213, and there is no limitation here.

[0045] In the embodiment, a mobile drive device in the prior art is provided, including a guide rail installed in the chassis 1 and a moving seat slidably connected to the guide rail, wherein the leg 2111 on the beam 211 is fixedly connected to the moving seat, and at the same time, the lower clamping block 22 is slidably connected to the moving seat in the vertical direction, and the motor is connected to the moving seat through a transmission system to drive the moving seat to reciprocate along the guide rail 03, and the clamping drive device is connected to the lower clamping block 212 to drive the lower clamping block 212 to reciprocate in the vertical direction, thereby realizing the clamping of the workpiece.

[0046] Embodiment 2

[0047] In this embodiment, the structure of the feeding fixture is substantially the same as that of the first embodiment. This embodiment provides another structural example for the upper chuck 21 .

[0048] like Figures 6 - 9 As shown, in this embodiment, the upper clamping head 21 also includes a cross beam 211 and an upper clamping assembly 212. The upper clamping assembly 212 also includes an upper clamping piece 213 and an adjusting mechanism 214, wherein legs 2111 for supporting the cross beam 211 are provided at both ends of the cross beam 211. The adjusting mechanism 214 is in transmission connection with the upper clamping piece 213 and is used to adjust the distance between the upper clamping piece 213 and the lower clamping block 22. In this embodiment, the upper clamping assembly 212 also includes a seat body 2121, and the adjusting mechanism 214 is arranged on the seat body 2121. The seat body 2121 is arranged on the cross beam 211.

[0049] At the same time, in this embodiment, the seat body 2121 is slidably connected to the beam 211 along the length direction of the beam 211, and the beam 211 is provided with an avoidance groove 2111 and a guide groove 2112 along the length direction. The upper clamping member 213 passes through the avoidance groove 2111 and clamps the workpiece to be transported with the lower clamping block 22, and a guide column 2144 is arranged on the seat body 2121 to limit the sliding along the guide groove 2112.

[0050] When the seat body 2121 is moved along the length direction of the beam 211, the corresponding positions of the upper clamping member 213 and the lower clamping block 22 can be changed, so that the clamping action of different workpieces can be realized, and it can adapt to the clamping work of more different workpieces.

[0051] After the seat body 2121 is moved and fixed to the cross beam 211, the guide post 2144 is threadedly connected to the seat body 2121, and a boss 2145 is formed at one end of the guide post 2144 passing through the guide groove 2112. The width dimension of the boss 2145 is larger than the width dimension of the guide groove 2112, so as to prevent the guide post 2144 from falling off within the guide groove 2112. When the seat body 2121 is moved to an appropriate position, the guide post 2144 is tightened, so that the boss 2145 and the cross beam 211 are pressed against each other to lock the seat body 2121 on the cross beam 211.

[0052] In this embodiment, in order to enhance the clamping effect on the workpiece, a plurality of upper clamping components 212 are arranged side by side on the cross beam 211, that is, a plurality of seat bodies 2121 sliding on the cross beam 211 are arranged side by side, so that the upper clamping components 212 can slide on the cross beam 211 through the seat bodies 2121. Similarly, an adjusting mechanism 214 and an upper clamping member 213 are arranged on each seat body 2121, so as to clamp the workpiece to be transported evenly at multiple points, ensure the balanced force of the workpiece, and have higher conveying accuracy.

[0053] In this embodiment, by arranging a plurality of upper clamping components 212, a plurality of upper clamping members 213 are arranged on the cross beam, and the upper clamping members 213 can be evenly arranged by sliding the seat body 2121 to clamp the workpiece evenly. Therefore, the upper clamping member 213 in this embodiment can be set as a columnar structure. At the same time, it is worth noting that in this embodiment, the adjusting mechanism 214 for adjusting the distance between the upper clamping member 213 and the lower clamping block 22 can adopt any technical solution in the prior art. In this embodiment, the adjusting mechanism takes a cylinder as an example, and drives the movement of the upper clamping member 213 through the cylinder, and then adjusts the distance between the upper clamping member 213 and the lower clamping block to adapt to the clamping of different workpieces.

[0054] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention is disclosed above in a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, when making some changes or modifications using the above-disclosed technical content as equivalent change equivalent embodiments, but as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical meaning of the present invention shall fall within the scope of the technical solution of the present invention.
