Description

Technical Field

[0001] This utility model belongs to the field of wear-resistant material processing technology for mining machinery, and specifically relates to a positioning device for processing wear-resistant materials for mining machinery. Background Technology

[0002] In the processing of wear-resistant materials for mining machinery, positioning devices play a crucial role. They not only ensure the accurate positioning of the workpiece during processing but also improve processing efficiency and product quality. Precise positioning reduces processing errors, avoids material waste, and simultaneously increases equipment utilization and processing accuracy.

[0003] Currently, existing positioning devices for processing wear-resistant materials in mining machinery typically require a trolley to move them to a designated location. However, moving the positioning device by trolley requires workers to lift it and mount it on the trolley, thus requiring additional lifting equipment. If there is no lifting equipment, it must be lifted manually, which reduces the ease of moving the device. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for processing wear-resistant materials in mining machinery. It aims to solve the problem that existing positioning devices for processing wear-resistant materials in mining machinery usually require a trolley to move the device to a designated position during use. However, moving the positioning device by trolley requires workers to lift it and place it on the trolley, which requires additional lifting equipment. If there is no lifting equipment, it needs to be lifted manually, thus reducing the convenience of moving the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for processing wear-resistant materials for mining machinery, comprising a base, two fixing plates symmetrically distributed on the top of the base, a lead screw threaded through the outer wall of the two fixing plates, a clamping positioning plate rotatably connected to one end of the lead screw, a first guide rod connected to one side of the clamping positioning plate, four support blocks connected to the bottom of the base, and a motor installed at one end of the base;

[0006] The output end of the motor is connected to a bidirectional lead screw. The outer wall of the bidirectional lead screw is threaded with two threaded connecting sleeves. The outer walls of the two threaded connecting sleeves are connected to a connecting crossbar. The end of the connecting crossbar away from the threaded connecting sleeve is rotatably connected to a rotating rod. The end of the rotating rod away from the connecting crossbar is rotatably connected to a lifting plate. The bottom of the lifting plate is equipped with four rollers. The interior of the base is connected to a second guide rod.

[0007] As a preferred embodiment of the positioning device for processing wear-resistant materials in mining machinery according to this utility model, the end of the bidirectional lead screw away from the motor is connected to the base through a bearing to form a rotating connection structure.

[0008] In a preferred embodiment of the positioning device for processing wear-resistant materials in mining machinery according to this utility model, the end of the connecting crossbar away from the threaded connecting sleeve is sleeved on the outer wall of the second guide rod.

[0009] As a preferred embodiment of the positioning device for processing wear-resistant materials for mining machinery according to this utility model, the bottom of the base has an opening, and the roller can extend to the outside of the base through the opening.

[0010] As a preferred embodiment of the positioning device for processing wear-resistant materials for mining machinery according to this utility model, the opening is provided in two parts, and the two openings are symmetrically distributed.

[0011] As a preferred embodiment of the positioning device for processing wear-resistant materials in mining machinery according to this utility model, the surface of the clamping positioning plate is bonded with an elastic rubber pad.

[0012] As a preferred embodiment of the positioning device for processing wear-resistant materials in mining machinery according to this utility model, the surface of the elastic rubber pad is provided with grooves.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The motor drives the bidirectional lead screw to rotate clockwise, which causes the two threaded connecting sleeves on its outer wall to move the connecting crossbar along the second guide rod. As it moves, the rotating rod at the end of the connecting crossbar rotates and drives the lifting plate to descend, allowing the rollers at the bottom of the lifting plate to extend outward through the opening and support the device after contacting the ground, thereby improving the ease of moving the device.

[0015] By rotating the lead screw through the rotating disk, the threaded connection between the lead screw and the fixed plate allows the two clamping positioning plates to move towards the center, thereby clamping and positioning the wear-resistant material of the mining machinery placed on top of the base. The elastic rubber pad can absorb and disperse the impact and vibration generated by the clamping force when the positioning plate clamps the material, preventing the clamped object from being damaged by direct force. At the same time, the rubber material has a high coefficient of friction, and the elastic rubber pad can increase the friction between the clamping surface and the clamped object, making the clamping more stable and preventing the object from sliding or falling off during the clamping process.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a positioning device for processing wear-resistant materials for mining machinery, including a base 1, two fixing plates 2 symmetrically distributed on the top of the base 1, a lead screw 3 threaded through the outer wall of the two fixing plates 2, a clamping positioning plate 4 rotatably connected to one end of the lead screw 3, a first guide rod 5 connected to one side of the clamping positioning plate 4, four support blocks 6 connected to the bottom of the base 1, and a motor 7 installed at one end of the base 1;

[0025] It should be noted that the end of the first guide rod 5 away from the clamping and positioning plate 4 passes through the surface of the fixed plate 2, so that the first guide rod 5 can play a guiding role during the movement of the clamping and positioning plate 4.

[0026] The output end of the motor 7 is connected to a bidirectional lead screw 8. The outer wall of the bidirectional lead screw 8 is threaded with two threaded connecting sleeves 9. The outer wall of the two threaded connecting sleeves 9 is connected to a connecting crossbar 10. The end of the connecting crossbar 10 away from the threaded connecting sleeves 9 is rotatably connected to a rotating rod 11. The end of the rotating rod 11 away from the connecting crossbar 10 is rotatably connected to a lifting plate 12. Four rollers 13 are installed at the bottom of the lifting plate 12. The inside of the base 1 is connected to a second guide rod 14.

[0027] Preferably, the end of the bidirectional lead screw 8 away from the motor 7 is connected to the base 1 through a bearing to form a rotating connection structure. The end of the connecting crossbar 10 away from the threaded connecting sleeve 9 is sleeved on the outer wall of the second guide rod 14. An opening 15 is provided at the bottom of the base 1. The roller 13 can extend to the outside of the base 1 through the opening 15. There are two openings 15, and the two openings 15 are symmetrically distributed.

[0028] In practical use, the motor 7 drives the bidirectional lead screw 8 to rotate clockwise, so that the two threaded connecting sleeves 9 connected to the outer wall can drive the connecting crossbar 10 to move in opposite directions along the second guide rod 14. As it moves, the rotating rod 11 at the end of the connecting crossbar 10 will rotate and drive the lifting plate 12 to descend, so that the roller 13 at the bottom of the lifting plate 12 can extend outward through the opening 15 and support the device after contacting the ground, thereby improving the convenience of moving the device.

[0029] It should be noted that the motor 7 drives the bidirectional lead screw 8 to rotate counterclockwise, so that the two threaded connecting sleeves 9 connected to the outer wall can drive the connecting crossbar 10 to move towards each other along the second guide rod 14. As it moves, the rotating rod 11 at the end of the connecting crossbar 10 will rotate and drive the lifting plate 12 to rise. Thus, when the device moves to the designated location, the roller 13 will be retracted, so that the support block 6 will contact the ground and provide support.

[0030] Among them, motor 7 has an external power supply and is connected to a control switch.

[0031] Preferably, an elastic rubber pad 16 is bonded to the surface of the clamping positioning plate 4, and the surface of the elastic rubber pad 16 has a groove 17.

[0032] In practical use, the screw 3 is rotated by the rotating disk. The threaded connection between the screw 3 and the fixed plate 2 allows the clamping and positioning plates 4 on both sides to move towards the center, thereby clamping and positioning the wear-resistant material of the mining machinery placed on the top of the base 1 for subsequent processing. The elastic rubber pad 16 can absorb and disperse the impact and vibration generated by the clamping force when the material is clamped by the positioning plate 4, preventing the clamped object from being damaged by direct force. At the same time, the rubber material has a high coefficient of friction, and the elastic rubber pad 16 can increase the friction between the clamping surface and the clamped object, making the clamping more stable and preventing the object from sliding or falling off during the clamping process. In addition, it prevents the surface of the clamped object from directly contacting the clamping tool during the clamping process, preventing the surface from being scratched, indented or corroded, and playing a role in protecting the appearance and surface quality of the object.

[0033] Working principle: First, the wear-resistant material for mining machinery is placed on top of the base 1. Then, the screw 3 is rotated by the rotating discs on both sides. The threaded connection between the screw 3 and the fixed plate 2 allows the clamping and positioning plates 4 on both sides to move towards the center, thereby clamping and positioning the wear-resistant material placed on top of the base 1 for subsequent processing. When the device needs to be moved, the motor 7 drives the bidirectional screw 8 to rotate clockwise, causing the two threaded connecting sleeves 9 on its outer wall to move the connecting crossbar 10 along the second guide rod 14. As it moves, the rotating rod 1 at the end of the connecting crossbar 10... After rotation, the lifting plate 12 will descend, allowing the rollers 13 at the bottom of the lifting plate 12 to extend outward through the opening 15 and support the device after contacting the ground. At this time, the device can be moved using the rollers 13. When the device moves to the designated location, the motor 7 drives the bidirectional lead screw 8 to rotate counterclockwise, causing the two threaded connecting sleeves 9 on its outer wall to drive the connecting crossbar 10 to move towards each other along the second guide rod 14. As it moves, the rotating rod 11 at the end of the connecting crossbar 10 will rotate and drive the lifting plate 12 to rise, retracting the rollers 13 and making the support block 6 contact the ground for support.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
