Description

Technical Field

[0001] This utility model relates to the field of assembly tooling technology, specifically to an assembly tooling for a combination type of chopsticks. Background Technology

[0002] Modern chopsticks have evolved in various forms, including modular chopsticks suitable for outdoor use. These modular chopsticks are detachable and can be packed into a smaller space than traditional chopsticks, making them convenient to store and carry. Modular chopsticks are connected by installing separate inserts. However, current technology involves manually embedding these inserts into the narrow cross-sections of the chopsticks, which requires significant processing time per piece and is not conducive to the production of products like chopsticks that are in high demand. Therefore, there is a need to design a dedicated, mass-producible tooling for modular chopsticks that can quickly assemble and install these inserts, thus shortening the embedding time. Utility Model Content

[0003] To address the issue of long installation time for the connecting parts of modular chopsticks mentioned in the background section, an installation fixture for modular chopsticks is proposed to shorten the installation time of individual pieces and enable batch assembly of the connecting parts.

[0004] This utility model discloses a combined chopsticks installation fixture, comprising a pushing mechanism, a clamping mechanism, a limiting mechanism, and a frame; the pushing mechanism is horizontally fixedly mounted on the frame, and has a pushing end capable of reciprocating horizontally; the limiting mechanism is fixedly mounted on the frame, located on the side of the pushing mechanism with the pushing end, and has several limiting grooves parallel to the movement direction of the pushing end; the clamping mechanism has a clamping end capable of repeated opening and closing, and the clamping end is located on the horizontal extension line of the opening direction of the limiting grooves.

[0005] As a further improvement of this utility model, the limiting mechanism includes a limiting mounting seat and a push rod; the limiting mounting seat is fixedly connected to the frame, and a number of equally spaced limiting grooves are opened on the upper side of the limiting mounting seat, in which the push rod is movably embedded; the push rod has a mating hole in the center of the side facing the clamping end of the clamping mechanism for inserting the workpiece to be assembled; the other end of the push rod extends out of the limiting groove and is located on the movement path of the pushing end of the pushing mechanism.

[0006] As a further improvement of this utility model, the pushing mechanism includes a pushing cylinder and a pushing block that are horizontally fixed on the frame, and the pushing block is fixedly connected to the output end of the pushing cylinder; the clamping mechanism includes a clamping cylinder, a clamping block one and a clamping block two, the clamping cylinder is vertically fixed on the frame, the clamping block one is fixedly connected to the output end of the clamping cylinder, the clamping block two is correspondingly arranged directly below the clamping block one and fixedly connected to the frame, and the clamping block one can abut against the clamping block two under the drive of the clamping cylinder; the abutment point of the clamping block one and the clamping block two corresponds horizontally to the pushing block.

[0007] As a further improvement of this utility model, clamping block one and clamping block two are made of elastically deformable material and have the ability to fit and adapt to the workpiece to be clamped.

[0008] As a further improvement of this utility model, a recessed groove is formed at the abutting surface of clamping block one and clamping block two. When clamping block one and clamping block two are in the abutting state, the extended line of the axis of the recessed groove corresponds horizontally to the limiting groove.

[0009] As a further improvement of this utility model, it also includes a limiting frame, which is fixedly set on the horizontal side of the opening of the limiting groove and located on the side away from the pushing end of the pushing mechanism; a through hole is opened in the middle of the limiting frame, and the through hole corresponds horizontally to the limiting groove.

[0010] As a further improvement of this utility model, an inclined chamfer is provided on the side of the push block near the limiting groove.

[0011] As a further improvement of this utility model, the push cylinder is provided with an adjustment device at the output end, which has the ability to adjust the stop position when the output end retracts.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The connecting inserts embedded in the cross-section of chopsticks are small in size, making them inconvenient for manual gripping and force application during installation. This invention utilizes a push rod to extend and enlarge the force application range of the connecting inserts, reducing the operational difficulty of insert installation. Furthermore, this invention features multiple parallel limiting grooves as installation stations, and utilizes a pushing mechanism capable of applying stable thrust for combined installation, enabling batch production of insert installation operations, greatly reducing the processing time of individual workpieces and improving production efficiency. In addition, this invention has a simple structure, low training difficulty, and is easy to operate. Attached Figure Description

[0014] Specific Implementation Example 1: Please refer to the appendix Figure 1 -Appendix Figure 6 , A combination chopsticks installation fixture includes a pushing mechanism 1, a clamping mechanism 2, a limiting mechanism, and a frame 4.

[0015] The frame 4 includes a horizontally positioned base plate and a vertically positioned vertical plate. The limiting mechanism includes a mounting base 3 and a push rod 301. The mounting base 3 is fixedly mounted on the horizontal base plate of the frame 4, as shown below. Figure 3 As shown, the upper side of the mounting base 3 has three equidistant limiting grooves 302. Each limiting groove 302 has a push rod 301 horizontally embedded in it. The center of the left end of the push rod 301 has a mating hole 3011 along the central axis, and the right end of the push rod 301 extends out of the limiting groove 302.

[0016] The pushing mechanism 1 is horizontally positioned on the right side of the mounting base 3. The pushing mechanism 1 includes a pushing cylinder 101 and a pushing block 102. The pushing cylinder 101 is horizontally fixed to the horizontal base plate of the frame 4. The pushing block 102 is fixedly connected to the left pushing end of the pushing cylinder 101. The left side wall of the pushing block 102 abuts against the right end face of the push rod 301. The pushing end of the pushing cylinder 101 moves parallel to the central axis of the push rod 301 within the limiting groove 302. Driven by the pushing cylinder 101, the pushing block 102 moves horizontally back and forth, pushing the push rod 301 to slide to the left within the limiting groove 302.

[0017] Clamping mechanism 2 is located on the left side of mounting base 3 and is used to clamp and fix the workpiece to be processed. Clamping mechanism 2 includes clamping cylinder 201, clamping block one 202, and clamping block two 203. Clamping cylinder 201 is vertically fixedly mounted on the vertical plate of frame 4, with the pushing end of clamping cylinder 201 facing downwards. Clamping block one 202 is fixedly connected to the pushing end of clamping cylinder 201. Clamping block two 203 is fixedly mounted on the horizontal base plate of frame 4 and located directly below clamping block one 202. The upper surface of clamping block two 203 is horizontal to the middle of limiting groove 302. Clamping block one 202 is driven by clamping cylinder 201 to perform reciprocating vertical lifting and lowering motion. Clamping block two 203 is located on the movement path of clamping block one 202, and clamping block one 202 can abut and fit against clamping block two 203 after descending. Figure 3 As shown, clamping block 1 202 and clamping block 203 each have three recessed grooves 204 on their contact surfaces. Each of the three recessed grooves 204 on clamping block 1 202 vertically corresponds to one recessed groove 204 on clamping block 203. When clamping block 1 202 descends and abuts against clamping block 203, the corresponding recessed grooves 204 can be joined to form a cylindrical cavity for clamping the workpiece. The central axis of the cylindrical cavity coincides with the central axis of the push rod 301 inside the limiting groove 302. Clamping blocks 1 202 and clamping block 203 are made of elastic material. When the workpiece is clamped in the cylindrical cavity, the elastic clamping blocks 1 202 and clamping block 203 can deform to tightly fit the workpiece and fix it in place.

[0018] The workpiece to be pushed and installed in this utility model includes chopsticks 5 and inserts 6, such as... Figure 6 As shown, the chopstick 5 has a mounting hole 501 at its largest diameter end along the central axis. The diameter of the left end of the insert 6 is slightly larger than the diameter of the mounting hole 501 and has knurling on its outer circumferential surface to increase friction; the diameter of the right end of the insert 6 is larger than the diameter of the mounting hole 501 but smaller than the diameter of the largest end of the chopstick 5, and a mating post with a diameter equal to that of the mating hole 3011 is extended from the center of the right end of the insert 6.

[0019] Operating principle: such as Figure 3 and Figure 4As shown, before the insert 6 is pushed and installed, the chopsticks 5, insert 6, and push rod 301 are pre-assembled. The left end of insert 6 is inserted into the mounting hole 501, and the right end of insert 6 is inserted into the docking hole 3011. Push rod 301 abuts against the right end of insert 6. Push rod 301 is then installed in the limiting groove 302, and the right end of push rod 301 abuts against the side wall of push block 102. The smaller diameter end of chopsticks 5 is embedded in the recessed groove 204 of clamping block 203. The pushing end of the driving clamping cylinder 201 extends downward, clamping block 1 202 and clamping block 2 203 abut against each other, and the smaller diameter end of chopsticks 5 is clamped and fixed. The pushing end of the driving cylinder 101 extends, the pushing block 102 moves to the left, and the push rod 301, which abuts against the pushing block 102, is driven to slide to the left along the limiting groove 302. The insert 6 is pushed to the left by the push rod 301, and the chopstick 5 is clamped and fixed and cannot move. The insert 6 is pushed and embedded into the mounting hole 501.

[0020] Preferably, the push block 102 has an inclined chamfer above the side that abuts against the push rod 301. When the push rod 301 is placed, the right end of the push rod 301 can slide down along the chamfered slope to abut against the side wall of the push block 102, which has the effect of facilitating the placement and installation of the push rod 301.

[0021] Preferred, such as Figure 2 As shown, an adjustable stud is horizontally arranged between the push cylinder 101 and the push block 102. When installing the insert 6 on chopsticks 5 of different lengths, the length of the right end of the push rod 301 extending out of the limiting groove 302 is different. By adjusting the extension length of the stud after screwing it in, the push block 102 abuts against the right end of the push rod 301 when the push cylinder 101 retracts, so as to achieve the adaptive processing of chopsticks 5 of different sizes.

[0022] Preferred, such as Figure 4 and Figure 5 As shown, a limiting frame 303 is provided between clamping block 203 and mounting base 3. A rectangular through hole is provided in the middle of the limiting frame 303. When the chopstick 5 is clamped, it passes through the through hole in the middle of the limiting frame. When clamping block 1 202 and clamping block 2 203 are separated, the chopstick 5 will stick to the surface of clamping block 1 202 and curl up. The limiting frame 303 can hold the chopstick 5 in place, prevent it from curling up, and prevent the chopstick 5 from falling off the equipment.

[0023] The above description is only a preferred embodiment of the present utility model and is intended to illustrate the principle and effect of the present utility model, and is not intended to limit the present utility model. All variations, modifications and substitutions within the spirit and principle of the present design are within the protection scope of the present utility model.
