Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane wear-resistant parts processing, in particular to a polyurethane wear-resistant parts positioning device. Background Art

[0002] Polyurethane wear-resistant parts are parts made of wear-resistant polyurethane materials, which have excellent wear resistance, impact resistance, good oil resistance, acid and alkali resistance and aging resistance. Therefore, polyurethane wear-resistant parts are widely used in industrial manufacturing, automotive parts, engineering machinery and building materials.

[0003] When existing polyurethane wear-resistant parts are being processed, they often shift due to the special shape of the polyurethane wear-resistant parts. Traditional technology uses a fixed ring to place the polyurethane wear-resistant parts inside it to achieve positioning. However, during the production process, the polyurethane wear-resistant parts will increase in size according to different specifications. Traditional fixed rings can only fix polyurethane wear-resistant parts of the same specifications. When polyurethane wear-resistant parts of other sizes need to be processed, the fixed ring needs to be replaced, which greatly increases the production cost.

[0004] Therefore, it is particularly important to improve the existing polyurethane wear-resistant part positioning device, design a new polyurethane wear-resistant part positioning device to solve the above technical defects, and improve the practicality of the overall polyurethane wear-resistant part positioning device.

[0011] As a preferred solution of the utility model, a movable plate is installed at one end of the forked rod away from the pressure rod, and rotating seats are installed at both ends of the movable plate. First connecting plates are installed on the top and bottom of the rotating seat, and a second connecting plate is installed on the side of the first connecting plate away from the rotating seat.

[0013] As a preferred solution of the utility model, the outside of the clamping block is provided with anti-skid grooves, the anti-skid grooves are distributed at equal intervals, and a second spring is installed between the first connecting plate and the second connecting plate.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0025] The positioning assembly 7 is used to position the polyurethane wear-resistant parts during production.

[0026] For further information, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the positioning assembly 7 includes a disc 701, a clamping block 702, a first spring 703 and a containing block 704. The disc 701 is mounted on the top of the base 1 and is located inside the first connecting rod 5 and the second connecting rod 6. The clamping block 702 is mounted on the top of the disc 701, and the first spring 703 is mounted inside the clamping block 702. The containing block 704 is mounted in the middle of the top of the disc 701 and is located at the end of the first spring 703 away from the clamping block 702. When producing polyurethane wear-resistant parts, it is prevented When operating the polyurethane wear-resistant part, it may be offset, causing damage to the product and affecting its product quality. By moving the clamping block 702 outward, the top of the disc 701 of the clamping block 702 is fanned out, and the middle of the polyurethane wear-resistant part is placed on the top of the containing block 704. The first spring 703 is expanded and retracted to store energy, so that the clamping block 702 is reset to its original position, thereby clamping the polyurethane wear-resistant part so that it is completely fixed inside the clamping block 702, effectively enhancing stability during operation.

[0027] Among them, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the outer part of the disc 701 is symmetrically provided with an extended edge 705, the top of the extended edge 705 is provided with a baffle plate 706, the inner part of the baffle plate 706 is provided with a pressure rod 707, and the end of the pressure rod 707 away from the baffle plate 706 is provided with a forked rod 708. By starting the telescopic cylinder 3, the linkage plate 4 is moved, so that the first connecting rod 5 is offset, thereby driving the second connecting rod 6 to follow the movement, so that the first connecting rod 5 and the second connecting rod 6 present a diamond shape, thereby completing the squeezing of the pressure rod 707, and realizing the sliding of the pressure rod 707 inside the baffle plate 706, thereby driving the forked rod 708 to follow the movement.

[0028] Furthermore, please see Figure 1 , Figure 2and Figure 3 When the lever 720 is in the unlocking position, the lever 720 is in the unlocking position, and the spring 712 is in the unlocking position, so that the lever 720 is locked and the spring 712 is locked.

[0029] For further information, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the outside of the clamping block 702 is provided with anti-slip grooves, which are distributed at equal intervals. A second spring is installed between the first connecting plate 710 and the second connecting plate 711. Through the design of the anti-slip grooves, the clamping column 712 and the extrusion plate 714 are in contact with the outside of the clamping block 702, increasing friction to prevent falling off and dislocation, and at the same time, the vibration force generated is unloaded by the second spring.

A connecting shaft 9 is installed inside the connecting frame 8, and the connecting frame 8 is connected to the base 1 through the connecting shaft 9. When the first connecting rod 5 is offset, the connecting frame 8 is rotated through the connecting shaft 9, thereby transmitting the rotational force to the second connecting rod 6.

[0031] In this embodiment, the implementation scenario is specifically as follows: when producing polyurethane wear-resistant parts, in order to prevent the polyurethane wear-resistant parts from being offset during operation, causing damage to the product and affecting its product quality, the clamping block 702 is moved outward so that the top of the clamping block 702 disk 701 expands in a fan shape, and the middle of the polyurethane wear-resistant part is placed on the top of the containing block 704. The first spring 703 is telescopically stored to restore the clamping block 702 to its original position, thereby clamping the polyurethane wear-resistant part so that it is completely fixed inside the clamping block 702, effectively enhancing the stability during operation. When the polyurethane wear-resistant parts appear in different sizes, the linkage plate 4 is moved by starting the telescopic cylinder 3, so that the first connecting rod 5 The displacement is performed so that the connecting frame 8 can rotate through the connecting shaft 9, thereby transmitting the rotational force to the second connecting rod 6, so that the first connecting rod 5 and the second connecting rod 6 are in a diamond shape, thereby completing the extrusion of the pressure rod 707, and realizing the sliding of the pressure rod 707 inside the baffle 706, thereby driving the forked rod 708 to follow the movement, thereby realizing the movement of the movable plate 709 in the direction of the clamping block 702, so that the clamping column 712 is fitted to the outer circumferential wall of the clamping block 702, and the extrusion plate 714 will be folded inside the stabilizing plate 713, so that the extrusion plate 714 is completely fitted to the outer wall of the clamping block 702, increasing the contact area, thereby pushing the clamping block 702, and completing the positioning and fixation of polyurethane wear-resistant parts of different sizes.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
