Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle shell production, in particular to a burr grinding device for electric vehicle shell production. Background Technique

[0002] After the injection molding of the electric vehicle shell is completed, it is necessary to grind the edge burrs. Since the shape of the electric vehicle shell is irregular, there is no fixed fixture tooling. Generally, the operator fixes the shell with one hand and uses a grinding machine to grind the edge of the shell with the other hand. Fixing the shell and using the grinding machine with one hand will result in insufficient stability, making it impossible to grind the edge of the shell flat at one time and reducing the work efficiency. Content of the Utility Model

[0003] The purpose of this application is to provide a burr grinding device for electric vehicle shell production to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the following technical solutions are provided in this application:

[0005] A burr grinding device for electric vehicle shell production includes a base and a positioning component installed on the base. The positioning component includes a cylinder, a bidirectional screw rod, and a rubber strip. The bidirectional screw rod is installed above the base. Two cylinders are provided, and the two cylinders are respectively movably installed on both sides of the bidirectional screw rod. The output end of the cylinder is fixedly installed with a bent rod, and the rubber strip is sleeved on the outer wall of the bent rod. One end of the bidirectional screw rod is installed with a motor, and the motor is fixedly installed above the base. The bidirectional screw rod is driven by the motor.

[0006] Preferably, both ends of the bidirectional screw rod are connected to the outer wall of the base through bearings, and the output end of the motor is fixedly connected to one end of the bidirectional screw rod. Threads are provided on both sides of the bidirectional screw rod, and the two sets of threads are mirror-symmetrically arranged. Sliders are fixedly installed on the outer walls of the two cylinders, and the two sliders are respectively installed on both sides of the bidirectional screw rod.

[0007] Preferably, balance rods are installed on both sides below the rubber strip, and the two balance rods are fixedly connected to the outer wall of the base. The two balance rods have the same shape and length and there is a gap between them. Two fixed rods are fixedly installed on the inner wall of the base, and the two cylinders are both installed between the two fixed rods. The outer walls of the two fixed rods are in contact with the outer walls of the cylinders.

[0008] The beneficial effects of the present utility model are as follows: By providing a positioning component, an operator can place the housing on a horizontal balance bar. The two rubber strips are attached to the inner wall of the housing and exert an outward expanding force, so that the two rubber strips fix the housing and the housing fits with the balance bar. In this way, the housing is kept in a horizontal fixed state and there is no occlusion of the housing edge, and the operator can quickly finish grinding the edge with a grinding machine.

[0012] The following elaborates on the preferred embodiments of the present utility model in conjunction with the attached drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. The directional terms mentioned in the present utility model, such as "up", "down", "front", "rear", "left", "right", "top", "bottom", etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0013] As Figure 1-2 shown, a burr grinding device for the production of an electric vehicle housing includes a base 1 and a positioning component installed on the base 1. The positioning component includes a cylinder 3, a bidirectional screw 2, and a rubber strip 6. The bidirectional screw 2 is installed above the base 1. There are two cylinders 3, and the two cylinders 3 are respectively movably installed on both sides of the bidirectional screw 2. The output end of the cylinder 3 is fixedly installed with a bent rod, and the rubber strip 6 is sleeved on the outer wall of the bent rod. One end of the bidirectional screw 2 is installed with a motor 5, and the motor 5 is fixedly installed above the base 1. The bidirectional screw 2 is driven by the motor 5.

[0014] Both ends of the bidirectional screw 2 are connected to the outer wall of the base 1 through bearings. The output end of the motor 5 is fixedly connected to one end of the bidirectional screw 2. Threads are provided on both sides of the bidirectional screw 2, and the two sets of threads are mirror-symmetrically arranged. Sliders 8 are fixedly installed on the outer walls of the two cylinders 3, and the two sliders 8 are respectively installed on both sides of the bidirectional screw 2.

[0015] Balancing rods 4 are installed on both sides below the rubber strip 6. The two balancing rods 4 are fixedly connected to the outer wall of the base 1. The two balancing rods 4 are identical in shape and length and there is a spacing between them. Two fixing rods 7 are fixedly installed on the inner wall of the base 1. Both cylinders 3 are installed between the two fixing rods 7. The outer walls of the two fixing rods 7 are in contact with the outer walls of the cylinders 3.

[0016] Embodiment: The operator places the electric vehicle housing above the balancing rod 4. The operator presses the housing by hand so that the edge of the housing is in contact with the balancing rod 4. The two cylinders 3 are activated and both drive the rubber strip 6 to rise so that the rubber strip 6 contacts the inner wall of the housing. Subsequently, the motor 5 is activated to drive the bidirectional screw 2 to rotate. The bidirectional screw 2 drives the two cylinders 3 to expand to both sides through the slider 8. The cylinders 3 move between the two fixing rods 7. The two rubber strips 6 are in contact with the inner wall of the housing and exert an outward expanding force, so that the two rubber strips 6 fix the housing and the housing is in contact with the balancing rod 4, so that the housing is horizontally fixed above the base 1. Subsequently, the operator releases the housing. At this time, the housing has been fixed. The operator can use a grinding machine to quickly grind the edge of the housing.
