Description

TECHNICAL FIELD

[0001] The utility model relates to the field of horseshoe welding technology, and specifically relates to a brake shoe welding device. BACKGROUND

[0002] The brake shoe is a friction pair of the drum brake, and in addition to having the strength and rigidity required as a component, it should also have a friction coefficient as high and stable as possible, and proper wear resistance, heat resistance, heat dissipation and heat capacity, etc. The brake shoe is divided into the leading shoe and the trailing shoe according to whether the rotation direction when the brake shoe is opened is consistent with the rotation direction of the brake drum. When the rotation direction when the brake shoe is opened is consistent with the rotation direction of the brake drum, it is called the leading shoe, has the brake "increasing force" effect, and is also called the "assistance shoe". On the contrary, it is called the trailing shoe, or the "decreasing force" shoe.

[0003] In the process of realizing the utility model, the inventor finds that the problems in the prior art have not been solved: the existing brake shoe welding device does not have a good auxiliary alignment condition, and personnel usually rely on work experience to manually hold the reinforcing rib plate to be placed in the middle on the upper side of the shoe, and hold the welding device with the other hand, and then weld the reinforcing rib plate and the shoe block through the welding holes in the reinforcing rib plate. This method is prone to misalignment, which affects the welding quality of the brake shoe, and improvement is urgently needed. Therefore, the present utility model provides a brake shoe welding device. UTILITY MODEL CONTENTS

[0023] See also Figure 1-3The utility model provides a technical solution: a brake shoe welding device, including a carrier plate 1, with support rods 11 fixedly installed at the four corners of the bottom of the carrier plate 1, and positioning holes are opened on both sides of the bottom end of the support rod 11, which can be movably penetrated by bolts through the positioning holes and screwed with the preset threaded structure on the support to achieve stable limit of the support plate 2, and support plates 2 are fixedly installed on both sides of the upper surface of the carrier plate 1, and an indicator sign 21 is fixedly installed on the bottom of the outer wall of a group of support plates 2, and the indicator sign 21 is fixedly connected to the support plate 2 through a bracket, and the operator can be informed of the corresponding use process through the guide text on the indicator sign 21, which is convenient for beginners to learn and use, and a support platform 3 is placed on the inside of the support plate 2; a cross bar 22 is movably passed through the top of the support plate 2, and a flange 27 is fixedly installed on the cross bar 22 near the inner side of the support plate 2, and a tension spring a26 is provided on the outer side of the cross bar 22, and the two ends of the tension spring a26 are respectively connected to the flange 27 and the support plate 2 The support plate 3 is fixedly connected to the support plate 1 through the support block 31. The upper surface of the support plate 3 is provided with an arc groove 34, and a horseshoe block 41 is placed in the arc groove 34. The shape of the arc groove 34 is adapted to the shape of the horseshoe block 41, and the shape of the top block 23 is adapted to the contour of the end of the reinforcing rib plate 4. The former is adapted to prevent the horseshoe block 41 from shaking and deviating, and the latter is adapted to support and position the reinforcing rib plate 4, which meets the requirements of use. A reinforcing rib plate 4 is placed on the top of the horseshoe block 41, and a plurality of groups of uniformly arrayed welding holes are provided in the reinforcing rib plate 4; an iron block b33 is fixedly installed on the front side of the support plate 3, and an electromagnet b5 is adsorbed and positioned on the iron block b33. Through holes 32 are provided on both sides of the support plate 3.

[0024] In this technical solution, components such as the tension spring a26, the electromagnet a24 and the top block 23 can be used in conjunction. During the use of the welding device, after the horseshoe block 41 is placed in place, the electromagnet a24 can be turned on, and the electromagnet a24 and the iron block a25 are adsorbed and positioned. At this time, the two groups of top blocks 23 are completely moved inward, and then the two ends of the reinforcing rib plate 4 are placed and positioned between the top blocks 23. At this time, the reinforcing rib plate 4 is located on the upper side of the horseshoe block 41, and then the welding operation is carried out. After welding is completed, the operation is reversed to move the cross bar 22 outward. Compared with the existing method, the centering welding can be more ideal, which indirectly improves the welding quality of the brake shoe.

[0025] In some technical solutions, a push rod 52 is movable through the through hole 32, the bottom end of the push rod 52 is fixedly connected to the electromagnet b5, and a tension spring b51 is sleeved on the outside of the push rod 52, and the two sides of the tension spring b51 are fixedly connected to the support 3 and the electromagnet b5 respectively.

At this time, the top rod 52 moves down and shrinks into the through hole 32. Conversely, after the welding of a single set of horseshoes is completed, the electromagnet b5 is turned off, and the tension of the tension spring b51 can drive the top rod 52 to rise, thereby lifting the horseshoes upward, making it easier for personnel to take away the welded horseshoes, which is efficient and convenient.

[0027] Working principle: It should be noted that the present invention is a brake shoe welding device, and its components are all universal standard parts or components known to those skilled in the art. Its structure and principle can be known to those skilled in the art through technical manuals or conventional test methods.

[0028] When a brake shoe welding device is used, the welding device is placed at a designated workstation and then connected to an external power source. During this time, the brake shoe assembly shoe block can be placed in the arc groove 34, and then placed directly above the shoe block 41 through the reinforcing rib plate 4. The welding machine is held and welded to the reinforcing rib plate 4 and the shoe block 41 through the welding hole of the reinforcing rib plate 4, thereby performing a welding process on the brake shoe.

[0029] By providing a tension spring a26, an electromagnet a24 and a top block 23, during the use of the welding device, after the horseshoe block 41 is put in place, the electromagnet a24 can be turned on, and the electromagnet a24 and the iron block a25 are adsorbed and positioned. At this time, the two groups of top blocks 23 are completely moved inward, and then the two ends of the reinforcing rib plate 4 are placed and positioned between the top blocks 23. At this time, the reinforcing rib plate 4 is located on the upper side of the horseshoe block 41, and then the welding operation is carried out. After the welding is completed, the reverse operation is performed to move the cross bar 22 outward. In the existing method, the central placement of welding can be made more ideal, which indirectly improves the welding quality of the brake shoes. By providing a tension spring b51 and a top block 23, before processing the horseshoes, the electromagnet b5 can be turned on to temporarily adsorb and position it with the iron block b33. At this time, the top rod 52 moves down and shrinks into the through hole 32. On the contrary, after the welding of a single set of horseshoes is completed, the electromagnet b5 is turned off, and the tension of the tension spring b51 can drive the top rod 52 to rise, which can lift the horseshoes upward, making it convenient for personnel to take away the welded horseshoes, which is efficient and convenient.
