Description

Technical Field

[0001] The present invention relates to the technical field of a lifting and feeding device for friction plates used in brake shoes, and particularly to a lifting and feeding device for friction plates used in brake shoes. Background Art

[0002] At present, a brake shoe is a friction pair of a drum brake. In addition to having the strength and stiffness required as a component, it should also have a friction coefficient that is as high and stable as possible, as well as appropriate wear resistance, heat resistance, heat dissipation, and heat capacity. Among them, the friction plate is one of the essential components for manufacturing brake shoes. The friction plates are installed in pairs on the brake shoes. The two friction plates are divided into a thick friction plate and a thin friction plate. The thick and thin friction plates are installed on the brake shoe as a group. When the existing friction plates for brake shoes are installed, generally, the thick and thin friction plates are respectively stacked beside the assembler, and the assembler takes the friction plates at the top of the two stacked thick and thin piles and rivets them on the bent plate of the brake shoe. However, when the friction plates are sent from the ground to the conveying table, they need to be taken one by one manually, which causes the assembler to constantly bend down to pick up materials, making it easy for the assembler to get fatigued and reducing the practicality. Summary of the Invention

[0003] In order to solve certain or some technical problems existing in the prior art, the purpose of the present application is to provide a lifting and feeding device for friction plates used in brake shoes, where the friction plates can be placed on the lifting and feeding table, avoiding repeated bending down to pick up, and improving the practicality.

[0004] To solve the above-mentioned existing technical problems, one of the purposes of the present application is achieved by adopting the following technical solutions:

[0005] A lifting and feeding device for friction plates used in brake shoes, which includes a conveying table, four legs symmetrically arranged on the left and right at the bottom of the conveying table, two columns symmetrically fixed at the right end of the conveying table front and back, a lifting and feeding assembly arranged between the two columns, and a lifting and feeding table arranged on the lifting and feeding assembly. The lifting and feeding table is used to place the friction plates, and the lifting and feeding assembly can convey the friction plates placed on the lifting and feeding table to a position at the same height as the conveying table.

[0006] Further, the lifting and feeding assembly includes a cross plate fixed between the two columns, a driving motor fixed on the top of the cross plate, a threaded rod penetrating through the cross plate and rotating forward and backward by the driving motor, a lifting plate screwed on the threaded rod, a lifting and feeding table detachably arranged on the lifting plate, and a number of limit columns fixed at the bottom of the cross plate and movably penetrating through the lifting and feeding table.

[0007] Further, several of the limiting posts are symmetrically arranged before and after with the threaded rod as the center.

[0008] Further, the lifting and feeding table is detachably arranged on the conveying table through the limiting component. The limiting component includes a socket opened on the rear side wall of the lifting plate for the lifting and feeding table to be inserted, two shells symmetrically fixed on the front and rear side walls of the lifting plate before and after, a slot opened on the outer side wall of the lifting and feeding table corresponding to the shell, a limiting rod penetrating through the outer side wall of the lifting table and the shell and capable of being inserted into the slot, a blocking rod located in the shell and fixedly connected with the limiting rod, and a limiting spring arranged between the blocking rod and the inner side wall of the shell and sleeved on the limiting rod.

[0009] Further, the inner diameter of the socket matches the outer diameter of the lifting and feeding table.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] (1) During use, an operator places the friction plate on the lifting and feeding table, and then operates the lifting and feeding component to lift the friction plate. In this way, the operator only needs to sit on the chair and place the friction plate on the lifting and feeding table, avoiding repeated bending to pick up, improving the practicability. Compared with the prior art, it solves the technical problem that "when sending the friction plate from the ground to the conveying table, it is necessary for the operator to pick up the friction plate one by one, resulting in the assembly personnel constantly bending down to pick up materials, which is easy for the assembly personnel to get fatigued and reduces the practicability".

[0022] Friction plate lifting and feeding device for brake shoes, which includes a conveying table 4. Four legs 5 are symmetrically arranged on the left and right at the bottom of the conveying table 4. Two columns 6 are symmetrically and fixedly arranged at the front and back of the right end of the conveying table 4. A lifting and feeding assembly 1 is arranged between the two columns 6. A lifting and feeding table 8 is arranged on the lifting and feeding assembly 1. The lifting and feeding table 8 is used to place friction plates.

This way only requires the operator to sit on a chair and place the friction plates on the lifting and feeding table 8, avoiding repeated bending to pick up, improving the practicality. Compared with the prior art, it solves the technical problem that "when sending the friction plates from the ground to the conveying table 4, it is necessary for the operator to pick them up one by one, resulting in the assembly personnel constantly bending down to pick up materials, which is likely to cause fatigue of the assembly personnel and reduce the practicality."

[0023] Furthermore, the lifting and feeding assembly 1 includes a cross plate 3 fixedly arranged between the two columns 6, a driving motor 7 fixedly arranged on the top of the cross plate 3, a threaded rod 9 penetrating through the cross plate 3 and rotating forward and backward by the driving motor 7, a lifting plate 11 screwed on the threaded rod 9, a lifting and feeding table 8 detachably arranged on the lifting plate 11, and a number of limiting columns 10 fixedly arranged at the bottom of the cross plate 3 and movably penetrating through the lifting and feeding table 8.

[0024] The lifting and feeding assembly 1 includes a cross plate 3 fixedly arranged between the two columns 6. A driving motor 7 is fixedly arranged on the top of the cross plate 3.

A number of limiting columns 10 are fixedly arranged at the bottom of the cross plate 3 and can movably penetrate through the lifting and feeding table 8. When in use, start the driving motor 7, and use the forward and backward rotation of the driving motor 7 to realize the height adjustment of the lifting and feeding table 8. The driving motor 7 drives the threaded rod 9 to rotate, and the threaded rod 9 drives the lifting and feeding plate to lift and lower, so as to realize the height adjustment. The limiting columns 10 play a role in limiting the lifting and feeding table 8.

[0025] Furthermore, a number of limiting columns 10 are symmetrically arranged before and after with the threaded rod 9 as the center.

[0026] Further, the lifting and feeding table 8 is detachably arranged on the conveying table 4 through the limiting component 2. The limiting component 2 includes a socket 14 formed on the rear side wall of the lifting plate 11 for the lifting and feeding table 8 to be inserted, two shells 12 symmetrically and fixedly arranged on the front and rear side walls of the lifting plate 11, a slot 17 formed on the outer side wall of the lifting and feeding table 8 corresponding to the shell 12, a limiting rod 13 penetrating between the outer side wall of the lifting table and the shell 12 and capable of being inserted into the slot 17, a stop rod 15 located in the shell 12 and fixedly connected to the limiting rod 13, and a limiting spring 16 arranged between the stop rod 15 and the inner side wall of the shell 12 and sleeved on the limiting rod 13.

A limiting spring 16 capable of being sleeved on the limiting rod 13 is arranged between the stop rod 15 and the inner side wall of the shell 12. By using the elasticity of the limiting spring 16, a tightening effect is exerted on the limiting rod 13. When the lifting and feeding table 8 needs to be disassembled and replaced due to wear after long-term use, the limiting rod 13 is pulled outwards, and the limiting rod 13 is pulled out from the limiting slot, and the lifting and feeding table 8 is freed from the limit, thus facilitating replacement.
