Description

Technical field:

[0001] The present application relates to the technical field of burr removal, and in particular to a device for removing burrs from corners of automobile leaf springs. Background technology:

[0002] Leaf springs are elastic elements composed of several alloy spring leaves of equal width and thickness but unequal length. They have the characteristics of large load-bearing capacity and strong impact resistance, and are widely used in vehicle suspension systems. The production process of leaf springs mainly includes: cutting, straightening, punching, ear curling, quenching, tempering, heat treatment, shot peening and assembly, among which cutting is to cut the spring flat steel provided by the steel mill into blanks of various lengths specified by the process. However, shear burrs often appear at both ends of the steel plate during the shearing process, which will aggravate the friction between the ends of the plate, cause gnawing of the upper and lower steel plates, and affect the service life.

[0004] The technical solution adopted in this patent can only remove burrs on the vertical surfaces at both ends of the steel plate. It is difficult to remove burrs at the edges and corners, especially burrs located on the upper and lower surfaces of the steel plate, which reduces the yield rate. These difficult-to-remove burrs can only be removed through manual secondary rework, which increases the workload and labor intensity of workers and is inefficient. Utility model content:

[0005] In order to solve the above technical problems, the utility model provides a device for removing burrs from the edges and corners of automobile leaf springs. The technical problem solved is that the burrs at the edges and corners of the steel plates and the upper and lower surfaces are difficult to remove, which reduces the yield rate and requires secondary rework to remove, increasing the labor workload and the labor intensity of the workers, resulting in low efficiency. In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0009] Two linear guide rails are arranged horizontally and perpendicularly to the conveying direction of the chain conveyor. The two linear guide rails are arranged on both sides of the chain conveyor respectively. The two linear guide rails are connected to the upper end surface of the frame in a fixed structure. Slide blocks are arranged on the two linear guide rails. The slide blocks are provided with locking mechanisms for fixing the slide blocks.

[0010] The housing is connected to the slider in a fixed structure, and channels for the leaf spring to pass through are provided on both sides of the housing.

[0012] Furthermore, the chain conveyor includes a frame and two sets of chains arranged in parallel, support plates are arranged on the chains at intervals, and both sides of the support plates are connected to the chain links of the chains through bolts; and the embedding grooves are arranged on the upper end faces of the support plates.

[0013] Furthermore, the power device is a servo motor.

[0014] Further, the distance between the two horizontal grinding wheels is the same as the thickness of the steel plate.

[0015] Furthermore, a waste basket is provided at the bottom of the shell.

[0016] Furthermore, the locking mechanism includes a bolt hole and a locking bolt. The bolt hole is arranged on a side surface of the slider parallel to the linear guide rail. One end of the locking bolt passes through the bolt hole and contacts the surface of the linear guide rail.

[0017] The beneficial effects of the utility model are:

[0018] 1. The vertical and horizontal grinding wheels are used to grind the vertical surfaces and corners of the spring sheet at the same time, which can remove the burrs on the vertical surfaces and corners at the same time, improve the yield rate, avoid secondary rework, and improve work efficiency.

[0025] In order to make the purpose, technical scheme and advantages of the implementation of the utility model clearer, the utility model will now be further described in detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the utility model. The specific implementation scheme of the utility model is as follows:

[0026] A device for removing burrs from corners of automobile leaf springs comprises a frame 1, wherein a chain conveyor 2 is arranged on the upper end surface of the frame 1 in a fixed structure manner, and the chain conveyor 2 is provided with an embedding groove 8 for fixing a steel plate; two linear guide rails 3 are arranged horizontally and perpendicular to the direction of the chain conveyor 2 on both sides of the chain conveyor 2, and are connected to the upper end surface of the frame 1 in a fixed structure manner; a slider 4 is arranged on each of the two linear guide rails 3, and a locking mechanism for fixing the slider 4 is arranged on the slider 4; a housing 5 is arranged on the slider 4 in a fixed structure manner, and the housing 5 can slide along the linear guide rail 3 to change the relative distance between the two housings 5, so as to grind steel plates of different lengths; channels for the leaf spring to pass through are opened on the vertical surfaces on both sides of the housing 5, so that the steel plate can directly enter the housing 5 for grinding during the conveying process, thereby improving efficiency; a vertical grinding wheel 6 and two horizontal grinding wheels 7 are arranged in the housing 5 in a rotating structure manner, and the two horizontal grinding wheels 7 are located on the same side of the vertical grinding wheel 6, so as to prevent the steel plate from warping due to uneven force during grinding, thereby affecting the grinding effect.

[0027] Furthermore, a power device is provided on the outside of the shell 5 for driving the vertical grinding wheel 6 and the horizontal grinding wheel 7 to rotate; the vertical surfaces and the corners at both ends of the spring sheet are simultaneously ground by the vertical grinding wheel 6 and the horizontal grinding wheel 7, so that the burrs on the vertical surfaces and the corners can be removed at the same time, thereby improving the yield rate, avoiding secondary rework, and improving work efficiency.

[0028] Specifically, the chain conveyor 2 includes a frame 21 and two sets of chains 22 arranged in parallel. Support plates 13 are arranged at intervals on the chains 22. Both sides of the support plates 13 are connected to the links of the chain conveyor 2 by bolts. Both sides of the support plates 13 are connected to the links of the chain 22 by bolts. The support plates 13 can prevent the steel plates from being scratched by the bolts when fixing the steel plates; the embedded grooves 8 are opened on the upper end surface of the support plates 13, and the width of the embedded grooves 8 is consistent with the width of the steel plates. The steel plates are placed in the embedded grooves 8 to ensure the horizontal stability of the steel plates during the grinding process; the support plates 13 are meshed and connected with the chain conveyor 2 so that the support plates 13 can move with the chain conveyor 2 to realize automatic grinding of the steel plates.

[0029] It should be noted that the power device is a servo motor 9, which is used to drive the grinding wheel to rotate; the distance between the two horizontal grinding wheels 7 is the same as the thickness of the steel plate, so that the steel plate can pass through the gap between the two horizontal grinding wheels 7 and grind the steel plate when passing through.

[0030] It should be explained that a waste basket 10 is provided at the bottom of the shell 5, and the polished waste directly enters the waste basket 10 to prevent the burrs from breaking into fragments or flying out in needle-like shapes, which can easily hurt people and cause damage to the surface of the machine tool; the waste basket 10 can also be pulled out and cleaned at any time to prevent waste accumulation.

[0031] Furthermore, the locking mechanism includes a bolt hole 11 and a locking bolt 12. The bolt hole 11 is opened on the side surface parallel to the linear guide rail 3. One end of the locking bolt 12 passes through the bolt hole 11 and abuts against the surface of the linear guide rail 3. After the locking bolt 12 is tightened, it can support the linear guide rail 3 and fix the position of the shell 5 to prevent the shell 5 from moving backward during the grinding process and affecting the grinding effect.

[0032] The working principle and working process of the utility model are as follows:

[0033] Place the steel plate horizontally in the embedded groove 8, and then slide the shell 5 along the linear guide 3. The sliding of the shell 5 drives the internal vertical grinding wheel 6, horizontal grinding wheel 7 and waste basket 10 to move together. After adjusting the positions of the shell 5, vertical grinding wheel 6 and horizontal grinding wheel 7 until both ends of the steel plate can be fully in contact with the vertical grinding wheel 6 and horizontal grinding wheel 7, tighten the locking bolts 12 to fix the position of the shell 5, and then start the servo motor 9. The servo motor 9 provides power to the vertical grinding wheel 6 and the horizontal grinding wheel 7 for rotation, and then start the chain conveyor 2. The steel plate moves with the rotation of the chain conveyor 2. When it moves to the position of the shell 5, it passes through the side channel of the shell 5, and then after being polished by the horizontal grinding wheel 7 and the vertical grinding wheel 6 in turn, it passes through the channel on the other side of the shell 5 and slides to the collection box at the end of the chain conveyor 2.
