Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a pressure plate positioning fixture. Background Technology

[0002] Bearing shells are essential components of every engine. They are the parts that contact the sliding bearing and the journal. The bearing shell is shaped like a tile-like semi-cylindrical surface with a very smooth surface. The main functions of the bearing shell are to bear the forces applied by the journal, maintain a stable oil film, ensure smooth bearing operation, and reduce bearing friction loss.

[0003] In the field of bearing processing, the bearing two-plane milling machine refers to the equipment that performs milling on the two end faces of the bearing. The two-plane milling machine needs to be maintained every five years, especially the guide rail assembly on the two-plane milling machine, which is the focus of maintenance. When maintaining the guide rail assembly on the two-plane milling machine, the pressure plate that mates with the guide rail is the main focus of maintenance. Because the pressure plate is irregularly shaped, an angle grinder is required to grind it. This grinding method is time-consuming, expensive, and particularly inconvenient for each maintenance. Therefore, at present, when maintaining the guide rail assembly, a new pressure plate is usually replaced. However, this method is also relatively wasteful of materials and costly. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a pressure plate positioning fixture to solve the problem of high maintenance cost of pressure plates for bearing bush two-plane equipment in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides a pressure plate positioning fixture for use on the pressure plate of a bearing milling machine. The pressure plate includes an assembly base surface and a positioning part. The positioning part includes three sequentially adjacent positioning surfaces, with a certain angle between any two adjacent positioning surfaces. Specifically, the pressure plate positioning fixture includes a fixed platform and at least two positioning blocks. The at least two positioning blocks are spaced apart and fixedly disposed on the fixed platform along its length. Each positioning block has a positioning groove that matches the positioning part on the pressure plate. A threaded hole is provided on one side wall of the positioning groove, and the threaded hole communicates with the positioning groove. A fastening screw is threaded into the threaded hole.

[0006] Furthermore, the fixed platform includes a magnetic chuck, the positioning block is magnetically fixed to the magnetic chuck, and the magnetic chuck is provided with a magnetic knob, which can control the magnetic on / off state of the magnetic chuck.

[0007] Furthermore, it also includes a driving device, on which a gear is fixedly connected, and the driving device is connected to the gear in a transmission connection, and the driving device is capable of driving the gear to rotate.

[0008] Furthermore, the driving device includes a rack base, a rack, and a driving cylinder. The rack is slidably disposed on the rack base and meshes with the gear. The driving cylinder is connected to the rack and is used to drive the rack to reciprocate.

[0009] Furthermore, two positioning blocks are provided.

[0010] As described above, the pressure plate positioning fixture of this utility model has the following beneficial effects: In use, the positioning fixture is placed under a surface grinder. Since the positioning block of the pressure plate positioning fixture is provided with a positioning groove that matches the positioning part on the pressure plate, when grinding the pressure plate, the positioning part of the pressure plate can be placed in the positioning groove on the positioning block. Then, by tightening the fastening screw, the fastening screw is pressed against the positioning surface, thereby securing the pressure plate in the positioning groove. Then, the grinding wheel of the surface grinder grinds the assembly base surface of the pressure plate. Compared with the prior art, the pressure plate positioning fixture of this utility model allows the pressure plate, which previously required an angle grinder for grinding, to be ground using a surface grinder. This makes pressure plate grinding more convenient and efficient, and the grinding cost is low. Furthermore, when repairing the guide rail assembly of two-plane equipment, it is no longer necessary to replace the pressure plate, greatly saving maintenance costs. Attached Figure Description

[0032] Please see Figures 1 to 2It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0033] This utility model provides a pressure plate positioning fixture, specifically applied to the pressure plate of a bearing milling machine with two flat surfaces, as detailed below. Figure 1 and Figure 2 As shown, the pressure plate 100 includes an assembly base surface 101 and a positioning part 102. The positioning part 102 includes three sequentially adjacent positioning surfaces 1021. The two adjacent positioning surfaces 1021 are at a certain angle. Specifically, the pressure plate positioning fixture includes a fixed platform 10 and at least two positioning blocks 20. The at least two positioning blocks 20 are spaced apart along the length of the fixed platform 10 and fixedly mounted on the fixed platform 10. Each positioning block 20 is provided with a positioning groove 201 that matches the positioning part 102 on the pressure plate 100. A threaded hole is provided on one side wall of the positioning groove 201. The threaded hole communicates with the positioning groove 201, and a fastening screw 2011 is threaded into the threaded hole.

[0034] The beneficial effects of the pressure plate positioning clamp of this utility model are: when in use, such as Figure 1 As shown, the positioning fixture is placed below the surface grinder. Since the positioning block 20 of the pressure plate positioning fixture is provided with a positioning groove 201 that matches the positioning part 102 on the pressure plate 100, when the pressure plate 100 is re-grinded, the positioning part of the pressure plate 100 can be placed in the positioning groove 201 on the positioning block 20, and then the fastening screw 2011 is tightened so that the fastening screw 2011 presses against a positioning surface of the positioning part 102, thereby fastening the pressure plate 100 in the positioning groove 201. Then, the grinding wheel 200 of the surface grinder is used to re-grind the mounting base surface 101 of the pressure plate 100. Compared with the existing technology, the pressure plate positioning fixture of this utility model can now be ground by a surface grinder instead of an angle grinder, making pressure plate grinding more convenient and efficient, and reducing grinding costs. Furthermore, when repairing the guide rail assembly of two-plane equipment, it is no longer necessary to replace the pressure plate, which greatly saves maintenance costs.

[0035] Specifically, such as Figure 1 As shown, in this embodiment, there are two positioning blocks 20, which are respectively located at the front and rear ends of the fixed platform 10.

[0036] Furthermore, such as Figure 1As shown, in this embodiment, the fixing platform 10 includes a magnetic chuck 11, and the positioning block 20 is magnetically fixed to the magnetic chuck 11. A magnetic knob (not shown) is provided on the magnetic chuck 11, which controls the magnetic on / off state of the magnetic chuck 11. With this structural design, the positioning block 20 is magnetically fixed to the magnetic chuck 11, and the positioning block 20 can be fixed or released by controlling the magnetic on / off state of the magnetic chuck 11 by turning the magnetic knob. The structure is simple and easy to assemble and disassemble.

[0037] Furthermore, considering that the positioning fixture is generally installed on a grinding machine, where the space is relatively small, making it inconvenient for the operator to turn the magnetic knob on the magnetic chuck 11, therefore, preferably, as Figure 1 As shown, in this embodiment, the positioning fixture also includes a driving device 30. Correspondingly, a gear 110 is fixedly connected to the magnetic knob of the magnetic chuck 11. The driving device 30 is connected to the gear 110 in a transmission manner, and the driving device 30 can drive the gear 110 to rotate. With this structural design, when it is necessary to turn the magnetic knob to control the magnetic on / off state of the magnetic chuck 11, the driving device 30 can be controlled to drive the gear 110 to rotate, thereby causing the gear 110 to drive the magnetic knob to rotate, thus realizing the control of the magnetic on / off state of the magnetic chuck 11. The operation is simple and convenient. The operator no longer needs to crawl into a narrow space with a wrench to turn the magnetic knob. The operator can control the forward and reverse rotation of the driving gear 110 from the outside through the driving device 30.

[0038] Furthermore, such as Figure 1 As shown, in this embodiment, the driving device 30 includes a rack base 31 and a rack 32 slidably disposed on the rack base 31, and a driving cylinder 33, wherein the rack 32 meshes with the gear 110, the driving cylinder 33 is connected to the rack 32, and the driving cylinder 33 can drive the rack 32 to reciprocate. For example, when the magnetic chuck 11 needs to release its magnetic force, the drive cylinder 33 pushes the rack 32 forward a certain distance, which in turn drives the gear 110 to rotate clockwise by a certain angle. The gear 110 then drives the magnetic knob to rotate clockwise by a certain angle, turning on the magnetic knob and allowing the magnetic chuck 11 to release its magnetic force. When the magnetic force of the magnetic chuck 11 needs to be turned off, the drive cylinder 33 pulls the rack 32 backward a certain distance (reset), which in turn drives the gear 110 to rotate counterclockwise by a certain angle. The gear 110 then drives the magnetic knob to rotate counterclockwise by a certain angle, resetting the magnetic knob and turning off the magnetic force of the magnetic chuck 11. The operation is simple and convenient.

[0039] In summary, this utility model provides a specialized positioning fixture for the pressure plate of a bearing milling machine with two flat surfaces. This fixture allows the pressure plate, which previously required an angle grinder for grinding, to be ground using a surface grinder. This makes pressure plate grinding more convenient, efficient, and cost-effective. Furthermore, when repairing the guide rail assembly of the two-flat surface equipment, it eliminates the need to replace the pressure plate, significantly reducing maintenance costs. Therefore, this utility model effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
