Description

Technical Field

[0001] This utility model relates to the field of manufacturing mining conveying equipment, and in particular to a processing tool for quick positioning and clamping of small pressure blocks. Background Technology

[0002] The small pressure block is a crucial component of the base body in the self-propelled machine's tail section. It ensures the inner cylinder liner can extend and retract freely within the outer cylinder liner. Because its position connects to the transfer conveyor on one side and the outer cylinder liner on the other, high positioning accuracy of the grooves and pin holes is required in the small pressure block to guarantee smooth installation of the base body, transfer conveyor, and outer cylinder liner. However, due to the small size of the small pressure block and its limited datum plane, there are insufficient datum surfaces available when machining the grooves and pin holes. Clamping is time-consuming and labor-intensive, frequently resulting in dimensional errors in the grooves and pin holes during machining. This obstructs the installation of the base body with the transfer conveyor and outer cylinder liner, preventing the inner cylinder liner from extending and retracting freely within the outer cylinder liner and the hydraulic cylinder. Summary of the Invention

[0003] In order to solve the technical problems existing in the above-mentioned technologies, it is necessary to provide a machining tooling for quick positioning and clamping of small pressure blocks.

[0004] A machining fixture for quick positioning and clamping of small pressure blocks includes a jig and a pad block;

[0005] Positioning cavities adapted to the shape of small pressure blocks are evenly distributed at equal intervals along the length direction of the upper end face of the fixture.

[0006] The pad is installed on the upper end face of the fixture and located between adjacent positioning cavities. The end of the pad can press against the upper end face of the small pressure block located on the side of the pad to clamp the small pressure block to be processed in the positioning cavity.

[0007] Preferably, the upper end face of the fixture has a positioning hole that penetrates the fixture between adjacent positioning cavities.

[0008] Preferably, the pad has an elongated hole that matches the positioning hole, so that the distance between the two ends of the pad and the adjacent small pressure block can be adjusted along the axis of the fixture.

[0009] Preferably, the width of the pad is adapted to the width of the side groove on the small pressure block.

[0010] Preferably, the lower end face of the pad has a recessed platform that can press against the upper end face of the small pressure block.

[0011] Compared with the prior art, the processing fixture for quick positioning and clamping of small pressure blocks provided by this utility model includes a jig and a pad; positioning cavities adapted to the shape of the small pressure blocks are evenly distributed at equal intervals along the length direction of the upper end face of the jig; the pad is installed on the upper end face of the jig and located between adjacent positioning cavities, and the end of the pad can press against the upper end face of the small pressure block located on the side of the pad, so as to clamp the small pressure block to be processed in the positioning cavity. This invention uses positioning cavities evenly distributed along the jig to fit the small pressure block, allowing the small pressure block to be accommodated within the positioning cavity and restricting its lateral movement. Then, pads are used to position the small pressure block longitudinally, achieving precise three-point positioning. No alignment is required; positioning and clamping are completed in one step, improving processing efficiency, solving the problem of processing reference, and ensuring the processing accuracy of holes and grooves. This replaces the processing method of scribing and drilling. The improved processing accuracy of grooves and holes ensures smooth installation of the base body, transfer mechanism, and outer cylinder liner, and guarantees the free extension and retraction of the inner cylinder liner within the outer cylinder liner and the hydraulic cylinder.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Please refer to Figures 1 to 3 This utility model provides a processing fixture for quick positioning and clamping of small pressure blocks, including a jig 01 and a pad 02;

[0022] The length of fixture 01 needs to be determined based on the size of the small pressure block and the length of the CNC machining center's worktable, and fixture 01 is made of wear-resistant plate. Positioning cavities 03, adapted to the shape of the small pressure block, are evenly distributed at equal intervals along the length of the upper surface of fixture 01.

[0023] The pad block 02 is installed on the upper end face of the fixture 01 and located between adjacent positioning cavities 03. The end of the pad block 02 can press against the upper end face of the small pressure block located on the side of the pad block 02 to clamp the small pressure block to be processed in the positioning cavity 03. In use, the positioning cavities 03, which are evenly distributed along the fixture 01, are adapted to fit the small pressure block, allowing the small pressure block to be accommodated in the positioning cavity 03 to restrict the left and right movement of the small pressure block. Then, the pad block 02 is used to position the small pressure block in the longitudinal direction, realizing three-point precise positioning of the small pressure block. No alignment is required. The slot and pin hole are processed in one positioning and one clamping, which improves the processing efficiency, solves the problem of processing datum, and ensures the processing accuracy of holes and slots, replacing the processing method of scribing and drilling. The improved processing accuracy of slots and holes ensures smooth installation of the base body, transfer machine and outer cylinder liner, and ensures that the inner cylinder liner can extend and retract freely with the oil cylinder in the outer cylinder liner.

[0024] Specifically, the upper end face of the fixture 01 is provided with a positioning hole 04 that penetrates the fixture 01 between adjacent positioning cavities 03. The positioning hole 04 is a threaded hole.

[0025] Specifically, the pad 02 has an elongated hole 05 that matches the positioning hole 04, so that the pad 02 can adjust the distance between the two ends of the pad 02 and the adjacent small pressure block along the axial direction of the jig 01, so as to ensure that the two ends of the pad 02 can press the small pressure block evenly.

[0026] The width of pad 02 is adapted to the width of the side groove on the small pressure block.

[0027] Please refer to Figure 4 , Figure 5 The lower end face of the pad 02 has a recess 06 that can press against the upper end face of the small pressure block. The recess 06 can press against the upper end face of the small pressure block, and the step formed by the recess 06 can hold against the side of the small pressure block to prevent the small pressure block from shifting when pressed down.

[0028] The small pressure blocks 07 to be processed are placed in batches into the fixture 01. Bolts are inserted into the elongated holes 05 and the positioning holes 04. The small pressure blocks 07 to be processed are then tightened and fixed with the pads 02 and bolts. The fixture 01 is fixed on the CNC machining center. After the fixture 01 is installed, batch processing can be carried out according to the processing program to achieve rapid positioning, rapid clamping, and smooth processing.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
