Description

Technical Field

[0001] The utility model belongs to the technical field of surface grinding for hub castings, and particularly relates to a surface grinding device for hub castings. Background Technique

[0002] A hub is a cylindrical metal component that supports the tire inside the tire profile and is centered on the shaft. It is also called a wheel rim, steel rim, wheel, or tire bell. Hubs come in a wide variety of types according to diameter, width, forming method, and material.

[0003] For example, the Chinese patent with the publication number CN218194241U discloses a burr cleaning device for automobile hub castings, which relates to the technical field of automobile hub production. It includes a base, a mounting plate fixed on the top of the base, a motor mounted at one end of the mounting plate, a driving rod whose output end is fixedly connected to the motor and movably penetrates through the mounting plate, a mounting seat fixed at one end of the driving rod, and an automobile hub casting main body arranged at one end of the mounting seat; a burr cleaning mechanism, which is arranged on the top of the base and is used to clean the burrs on the surface of the automobile hub casting main body. The automobile hub casting main body is fixedly connected to one end of the mounting seat through a fixing bolt. The burr cleaning mechanism includes fixing plates symmetrically fixed on the top of the base. The utility model replaces the existing manual grinding method, greatly improves the cleaning and removal efficiency of burrs or flash on the surface of the automobile hub casting main body, and has a good cleaning effect, which helps to improve the quality of the automobile hub casting main body.

[0004] The above patent has the following problems:

[0005] When the above patent is in use, there are some disadvantages. For example, when installing the hub, a worker needs to pull two pull rings by hand to move two grinding plates away from each other, and then another worker can install the hub. This process is rather inconvenient. Moreover, the connecting rod in the device is cylindrical, and when the hub rotates at a high speed, the connecting rod may rotate, which will affect the stability of the grinding block. In view of this, we propose a surface grinding device for hub castings. Content of the Utility Model

[0006] The purpose of the utility model is to provide a surface grinding device for hub castings to solve the problems raised in the above background technique.

[0007] In view of this, the utility model provides a surface grinding device for hub castings, including:

[0008] Base, two support plates are fixedly installed at the top of the base, fixed blocks are fixedly installed on the sides of the two support plates away from each other, a first chute is opened in the fixed block, a sliding block is slidably installed in the first chute, opposite ends of the two sliding blocks respectively penetrate through the two support plates and are both fixedly installed with mounting plates, a grinding block is fixedly installed on one side of the mounting plate, a first pull rod is fixedly installed at the other end of the sliding block, and the away ends of the two first pull rods respectively penetrate through the two first chutes and both extend to the outside. A first spring is sleeved on the first pull rod in the first chute; a limiting groove is opened at the bottom of the mounting plate;

[0009] Two rectangular blocks are respectively fixedly installed on the opposite sides of the two support plates. A second chute is opened in the rectangular block, a limiting block is slidably installed in the second chute, a second pull rod is fixedly installed at the bottom of the limiting block, and one end of the second pull rod penetrates through the second chute and extends to the outside. A second spring is sleeved on the second pull rod in the second chute;

[0010] Connecting plate, the connecting plate is fixedly installed at the top of the base, a rotating rod is rotatably installed on one side of the connecting plate, and a motor is fixedly installed on the other side of the connecting plate. The output shaft of the motor penetrates through the connecting plate and is coaxially connected with the rotating rod.

[0011] In this technical solution, during use, the staff can pull the two first pull rods by hand to drive the sliding blocks to displace. Subsequently, the sliding blocks will enter the first chutes. At this time, the first springs will be squeezed by the sliding blocks and contract. Then, the sliding blocks will drive the mounting plates to displace towards the fixed blocks. Subsequently, the mounting plates will drive the grinding blocks to displace towards the fixed blocks. Subsequently, the bottom of the mounting plate will contact the top of the limiting blocks, causing the mounting plates to squeeze the limiting blocks to displace downward. At this time, the limiting blocks will drive the second pull rods to displace downward, and the second springs will be squeezed by the limiting blocks and contract until the limiting blocks completely enter the second chutes. Subsequently, the mounting plates will contact the support plates. At this time, under the action of the rebounding force of the second springs, the second springs will push the limiting blocks to displace upward until the limiting blocks are inserted into the limiting grooves. At this time, the mounting plates will be fixed;

[0012] Subsequently, the staff fixed the hub on the rotating rod through several bolts and wrenches. Subsequently, two pull rods two can be pulled downward, causing the pull rod two to drive the limiting block to displace downward. Subsequently, the spring two will contract under the extrusion of the limiting block until the limiting block is completely withdrawn from the limiting groove. At this time, the sliding block will be released from the limit. Subsequently, under the action of the elastic force of the spring one, the spring one will push the sliding block to displace towards the direction close to the hub. The sliding block will drive the mounting plate to displace towards the hub, and the mounting plate will drive the grinding block to displace towards the hub until the grinding block contacts and abuts against the hub. Subsequently, the motor is started, and the output shaft of the motor drives the rotating rod to rotate. Subsequently, the rotating rod will drive the hub to rotate. While the hub is rotating, the two grinding blocks always abut against the hub, so that the hub can be ground.

[0013] In the above technical solution, further, the sliding block is slidably connected to the support plate.

[0014] In this technical solution, it is ensured that the sliding block can slide normally.

[0015] In the above technical solution, further, the pull rod one is slidably connected to the chute one and the fixed block.

[0016] In this technical solution, it is ensured that the pull rod one can slide normally.

[0017] In the above technical solution, further, the two ends of the spring one are respectively tightly welded to the other end of the sliding block and the inside of the chute one.

[0018] In this technical solution, it is ensured that the rectangular block does not hinder the displacement of the mounting plate and the pull rod two can slide normally.

[0019] In the above technical solution, further, the limiting block is inserted and matched with the limiting groove, and the top of the limiting block is of an inclined structure.

[0020] In this technical solution, it is ensured that the rectangular block does not hinder the displacement of the mounting plate and the pull rod two can slide normally.

[0021] In the above technical solution, further, the limiting block is inserted and matched with the limiting groove, and the top of the limiting block is of an inclined structure.

[0022] In this technical solution, it is ensured that the rectangular block does not hinder the displacement of the mounting plate and the pull rod two can slide normally.

[0023] In the above technical solution, further, the two ends of the spring two are respectively tightly welded to the inner wall of the chute two and the bottom of the limiting block. The cross-section of the sliding block is of a rectangular structure, and the cross-section of the chute one is of a rectangular structure.

[0024] In this technical solution, the structure of the second spring is ensured to be stable; the structure stability of the sliding block during displacement in the first chute is guaranteed, and the situation of rotation will not occur.

[0025] In the above technical solution, further, the rotating rod is located between the two grinding blocks, the output shaft of the motor is rotatably connected to the connecting plate, and a collection box is inserted and installed on the top of the base and between the two support plates.

[0026] In this technical solution, it is ensured that the hub fixed on the rotating rod can be ground by the two grinding blocks; it is guaranteed that the motor can operate normally; the collection box can collect the grinding debris.

[0027] The beneficial effects of the present utility model are:

[0028] 1. For the surface grinding device for hub castings, through the cooperation among the rectangular block, the second chute, the second spring, the second pull rod, the limiting block and the limiting groove, it is ensured that when installing the hub, the two mounting plates can be separated from each other first and fixed, without the need for the staff to keep pulling the first pull rod all the time. This process only requires one staff member to complete the installation of the hub, which is relatively convenient.

[0029] 2. For the surface grinding device for hub castings, through the cooperation between the sliding block and the first chute, since the cross-sections of the sliding block and the first chute are both rectangular structures, the sliding block will not rotate, making the grinding block more stable during grinding.
