Description

Technical Field

[0001] The utility model belongs to the technical field of processing fixtures, in particular to a wear-resistant tooth plate clamping tool. Background Art

[0002] Crushing equipment usually uses Figure 1 The wear-resistant tooth plate shown is usually formed by casting. The front of the tooth plate has a number of protruding teeth for crushing materials, and the back of the tooth plate is used to connect to the fixed surface on the crushing equipment. Therefore, after casting, the mounting surface on the back needs to be machined to be flat. In the existing processing, the tooth plate is mainly fixed by the combination of pads and pressure blocks. The main principle is to place the front of the tooth plate facing down, set pads at the gaps corresponding to the teeth on the mounting platform of the machine tool, and set at least four pads on the front of the entire tooth plate. Then, the pressure blocks are connected by T-bolts vertically set on the mounting platform, and the pressure blocks are used to press and fix the four sides of the tooth plate. This fixing method requires many parts to be disassembled and assembled, and the disassembly and assembly process is relatively cumbersome, which has a certain impact on the processing efficiency. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, the utility model provides a wear-resistant tooth plate clamping tool, which has high clamping efficiency and reduces the impact on processing efficiency.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A wear-resistant tooth plate clamping tool comprises: a base plate, with two groups of clamping rods on the top, the two clamping rods in each group are movably arranged along the direction of the line connecting them, and the two clamping rods in each group are provided with slots at the same height on opposite sides thereof, the slots are parallel to the base plate, one end of the slots of one pair of clamping rods facing the outside of the base plate has a baffle, and the outer side of the other pair of clamping rods is provided with a push rod, which is parallel to the slot, the push rod is movably arranged along the axis, and the front end of the push rod faces the baffle.

[0006] The beneficial effect of the utility model is that four clamping rods can be used to quickly clamp and position the two sides of the tooth plate, reducing the steps of adjusting the pad and the pressure block, effectively improving the clamping efficiency, and using the baffle and the push rod to limit the two ends of the tooth plate, further improving the clamping stability.

[0012] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0013] like Figure 2 , Figure 3 As shown, a wear-resistant tooth plate clamping tool comprises: a base plate 1, which is fixed to the mounting platform of the machine tool by bolts. Two groups of clamping rods 2 are arranged on the top of the base plate 1. The two clamping rods 2 of each group are arranged to move along the direction of the line connecting them, and the two clamping rods 2 of each group are arranged to have a slot 21 at the same height on the opposite side, and the slot 21 is parallel to the base plate 1. One end of the slot 21 of a pair of clamping rods 2 facing the outside of the base plate 1 has a baffle 22. It can be understood that the slot 21 does not penetrate the side wall of the clamping rod 2 facing the outside of the base plate 1, so that the baffle 22 is formed by using the side wall; as another structure, the baffle 22 can also be a structure that is separately arranged on the side wall of the clamping rod 2 and located outside the slot 21. The outer side of the other pair of clamping rods 2 is provided with a push rod 3, which is parallel to the slot 21, and the push rod 3 is arranged to move along the axis, and the front end push rod 3 faces the baffle 22.

[0014] When clamping, first, the teeth of the tooth plate face downward, and the two side edges of the tooth plate are clamped in the slots 21 on the four clamping rods 2; then, the front end of the push rod 3 is used to push the tooth plate to move toward the baffle 22 until the end face of the tooth plate is pressed against the baffle 22. In this process, the paired clamping rods 2 can be driven to move toward the middle at the same time until the two side edges of the tooth plate are pressed, and the clamping work of the wear-resistant tooth plate is completed; when disassembling, it is only necessary to loosen the push rod 3 and move the clamping rod 2 outward, which reduces the steps of adjusting the pad block and has fewer parts to be disassembled, which can effectively improve the disassembly and assembly efficiency; as a preference, the push rod 3 and the clamping rod 2 can be driven by independently arranged cylinders or linear motors to further improve the disassembly and assembly efficiency while ensuring the clamping stability.

[0015] Preferably, Figure 2 , Figure 3As shown, the top surface of the base plate 1 corresponds to each group of clamping rods 2 and is provided with a slide rail 11, the slide rail 11 is parallel to the moving direction of the clamping rod 2, the bottom of the clamping rod 2 is slidably arranged on the slide rail 11, and the cross-section of the slide rail 11 is a T-shaped structure. If a cylinder is used to drive the clamping rod 2, a cylinder can be arranged at both ends of the slide rail 11.

[0016] Further preferably, Figure 2 , Figure 3 As shown, a bidirectional screw rod 4 is provided above the base plate 1 corresponding to each group of clamping rods 2, and its two ends have threads with opposite rotation directions. The two ends of the bidirectional screw rod 4 are respectively passed through the two clamping rods 2 of the same group, and the midpoint of the bidirectional screw rod 4 is located in the middle of the two clamping rods 2 of the same group. In this way, the two clamping rods 2 of the same group can be moved synchronously in the same or opposite directions by rotating the bidirectional screw rod 4, so as to realize the process of rapid clamping and loosening. The bidirectional screw rod 4 is manually rotated or driven by a motor.

[0017] Preferably, Figure 2 , Figure 3 As shown, a worm gear 41 is coaxially provided in the middle of the bidirectional screw rod 4, and a driving rod 5 is provided above the base plate 1, which is vertically arranged on the two bidirectional screw rods 4 and parallel to the top surface of the base plate 1. The driving rod 5 is provided with a worm 51 corresponding to the worm gear 41 of the two bidirectional screw rods 4, and the worm 51 is meshed with the worm gear 41. By rotating the driving rod 5, the two bidirectional screw rods 4 can be synchronously driven to rotate. The driving rod 5 is driven by a motor or rotated manually.

[0018] Preferably, Figure 2 , Figure 3 As shown, the push rod 3 is passed through one of the horizontal plates of a Z-shaped support frame 6, and the other horizontal plate of the support frame 6 is connected to the side wall of the clamping rod 2 by a screw 7. The support frame 6 is rotatably arranged around the screw 7. By rotating the support frame 6, the contact position between the push rod 3 and the end face of the tooth plate can be adjusted to facilitate finding a more suitable clamping surface, and the clamping position can be adjusted according to the curvature of the tooth plate to adapt to tooth plates with different curvatures.

[0019] Preferably, when the push rod 3 is driven by a cylinder, the cylinder is arranged on a horizontal plate through which the push rod 3 is passed.

[0020] Preferably, the push rod 3 is a screw structure, and its position along the axial direction can be adjusted by rotation. At the same time, the self-locking function of the thread can be used to achieve the purpose of pressing the tooth plate.

[0021] Preferably, Figure 2 As shown, the cross section of the slot 21 is a V-shaped structure to accommodate tooth plates of different thicknesses and different arc angles.

[0022] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
