Description

Technical Field

[0001] The utility model relates to the technical field of brake shoe production, in particular to a size detection device for brake shoe quality inspection. Background Art

[0002] The brake shoe is an important component of the brake system. It is the supporting structure of the brake shoe. When affected by the brake cam or push rod, it will expand outward and press the brake drum to produce a braking effect. Its shape is like a half-moon. During its production process, the staff needs to detect its bending curvature to ensure the smooth progress of subsequent assembly work.

[0003] The Chinese patent authorization announcement number is CN216668544U, and the name is a plate curvature inspection tool, comprising: a first bracket, a first reference surface on the outer side of which is configured as a vertical plane; a second bracket, a second reference surface on the upper surface of which is configured as a horizontal plane; wherein the first bracket is configured to be located above the second bracket, and the distance between the first bracket and the second bracket satisfies: when the lower edge of the plate to be inspected is horizontally placed on the second reference surface of the second bracket, the upper edge of the plate can be placed on the first reference surface of the first bracket and is located in the area within the first reference surface, so that the plate to be inspected can be placed on the inspection tool in an upright state with both ends suspended to perform accurate inspection of the curvature item, and has the advantages of scientific structure, convenient operation, objective inspection, accurate results, etc.

[0004] The shortcomings of the above-mentioned prior art solution are: although the above-mentioned solution is relatively convenient to operate during detection, the number of brake shoes is often large when performing curvature detection, and the brake shoes are generally composed of two parts: an iron lining and a friction plate. The friction plate is prone to cracking when it is bumped, which makes it inconvenient to cut the brake shoes, and also reduces the production efficiency of the device and the yield rate of the product. Utility Model Content

[0005] The purpose of the utility model is to provide a size detection device for brake shoe quality inspection to solve the technical problems mentioned in the above background technology.

[0006] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0007] A size detection device for brake shoe quality inspection comprises a detection platform, a curvature detection fixture arranged on the top of the detection platform, and a storage slot opened on the top of the detection platform;

[0008] It also includes a buffer component, which includes a feed rack rotatably arranged inside the storage groove, a plurality of adjustment holes symmetrically opened on the inner side of the feed rack, a fixed plate inserted into the adjusting holes, and the fixed plates are staggered and symmetrically distributed, a buffer spring arranged on one side of the fixed plate, a receiving plate arranged on the top of the buffer spring, and a groove is opened on the top of the receiving plate, a plurality of feed rollers rotatably arranged inside the groove, and the outer side of the feed rollers is covered with a rubber sleeve, a plurality of buffer air bags arranged between the fixed plate and the receiving plate, and the buffer air bags are located between the buffer springs, and a one-way air inlet nozzle and a one-way exhaust nozzle are arranged on one side of the buffer air bags.

[0009] As a further solution of the utility model: the receiving groove is located at one side of the curvature gauge, and a plurality of groups of positioning pins matching the inner diameter of the adjustment hole are arranged on the side of the fixing plate.

[0010] As a further solution of the utility model: two groups of limiting plates are symmetrically arranged at the bottom of the unloading rack, through holes are opened on the inner sides of the limiting plates, and a lifting handle is arranged at one end of the bottom of the unloading rack.

[0011] As a further solution of the utility model: two groups of side panels are symmetrically arranged at the bottom of the detection platform, and a plurality of groups of angle holes distributed at intervals are opened on the inner sides of the side panels.

[0012] As a further solution of the utility model: a limit pin is arranged inside the angle hole, a material storage box is arranged below one end of the detection platform, and the material storage box is located below the unloading rack.

[0013] Beneficial effects of the utility model:

[0014] 1. When the brake shoe is tested and qualified for unloading, the gravitational potential energy of the brake shoe is converted into kinetic energy to drive the unloading roller to rotate. When the unloading roller rotates, it can absorb a part of the kinetic energy, and the rest of the kinetic energy is transmitted to the buffer spring. The buffer spring is deformed and compressed, and the buffer airbag collapses to exhaust air. The two cooperate to absorb energy well. Multiple groups of buffer components arranged in a staggered and symmetrical manner can absorb the kinetic energy of the brake shoe step by step, thereby absorbing the kinetic energy generated when the brake shoe falls, ensuring that the brake shoe will not generate a large impact force when falling into the storage box, thereby forming a good unloading protection for the brake shoe. When the buffer airbag is reset, the amplitude and frequency of the buffer spring rebound can be reduced, thereby ensuring normal energy absorption in subsequent use;

[0015] 2. The utility model can respectively install limit pins by setting two sets of side panels. When the limit pin is fixed at one end of the testing table, the unloading rack can be placed horizontally in the storage slot, which is convenient for the staff to store and does not occupy additional storage space, making it convenient to carry. When in use, the limit pin is fixed at the other end to support and fix the bottom of the unloading rack, so that the unloading rack can be tilted at a certain angle to facilitate unloading.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-3 As shown, a size detection device for brake shoe quality inspection comprises a detection platform 1, a curvature gauge 2 arranged on the top of the detection platform 1 and a storage slot 3 opened on the top of the detection platform 1, wherein the storage slot 3 is located on one side of the curvature gauge 2. When the device detects the curvature of the brake shoe, the staff can insert the brake shoe to be detected into the curvature gauge 2. If the shoe can be inserted smoothly, the curvature meets the specification, otherwise the curvature does not meet the specification, which is convenient and quick.

[0022] The invention also includes a buffer component, which includes a feed rack 4 rotatably arranged inside the storage groove 3, a plurality of adjustment holes 5 symmetrically opened inside the feed rack 4, a fixing plate 6 inserted into the adjusting hole 5, and the fixing plate 6 is staggered and symmetrically distributed, and a plurality of positioning pins matching the inner diameter of the adjusting hole 5 are arranged on the side of the fixing plate 6, a buffer spring 7 is arranged on one side of the fixing plate 6, a receiving plate 8 is arranged on the top of the buffer spring 7, and a groove is opened on the top of the receiving plate 8, a plurality of feed rollers 9 rotatably arranged inside the groove, and the outer side of the feed rollers 9 is covered with a rubber sleeve, a plurality of buffer air bags 10 are arranged between the fixing plate 6 and the receiving plate 8, and the buffer air bags 10 are located between the buffer springs 7, a one-way air inlet nozzle 11 and a one-way air exhaust nozzle 12 are arranged on one side of the buffer air bags 10, and the feed rack 4 tilted downward is used to transport the qualified brake shoes to the storage box 18, so as to facilitate the collection and transportation by the staff, and the brake shoes are on the feed rack 4. When moving upward, it will collide with the discharge roller 9, and the rubber sleeve ensures that there will be no rigid contact between the two, thereby forming a good protection for the two. The gravitational potential energy of the brake shoe is converted into kinetic energy during transportation, which can drive the discharge roller 9 to rotate. The discharge roller 9 absorbs a part of the kinetic energy when rotating, and the rest of the kinetic energy is transmitted to the buffer spring 7 through the discharge roller 9. The buffer spring 7 is deformed and compressed, and the buffer airbag 10 collapses to exhaust gas. The two can cooperate to absorb energy well. Multiple groups of buffer components arranged in an alternating and symmetrical manner can absorb the kinetic energy of the brake shoe step by step, and when the extrusion disappears, the buffer airbag 10 can reduce the amplitude and frequency of the buffer spring 7 when it rebounds, thereby ensuring normal energy absorption for subsequent use. The kinetic energy generated when the brake shoe falls can be absorbed by the buffer component set, ensuring that the brake shoe will not generate a large impact force when falling into the storage box 18, thereby forming a good discharge protection for the brake shoe.

[0023] In the present embodiment, specifically, two groups of limit plates 13 are symmetrically arranged at the bottom of the unloading rack 4, and a through hole 14 is opened on the inner side of the limit plate 13. A lifting handle is arranged at one end of the bottom of the unloading rack 4, and two groups of side plates 15 are symmetrically arranged at the bottom of the testing platform 1. A plurality of groups of angle holes 16 with intervals are opened on the inner side of the side plate 15, and a limit pin rod 17 is arranged inside the angle hole 16. A storage box 18 is arranged below one end of the testing platform 1, and the storage box 18 is located below the unloading rack 4. When the device is not in use, the unloading rack 4 is horizontally placed inside the storage slot 3, and the limit pin rod 1 7 are fixed at both ends in a group of side plates 15 arranged at one end of the testing platform 1, thereby penetrating a group of limit plates 13 arranged at one end of the bottom of the unloading rack 4 to fix one end of the unloading rack 4, thereby ensuring the stability of the unloading rack 4 when stored, making it convenient for the staff to store the unloading rack 4 so that it will not occupy additional storage space and is convenient for carrying. When in use, the limit pin rod 17 is removed and inserted into another group of side plates 15 to support and fix the other end of the bottom of the unloading rack 4, so that the unloading rack 4 can be tilted at a certain angle to facilitate unloading.
