A piston housing auxiliary detection device

Abstract

This utility model discloses an auxiliary inspection device for piston housings, relating to the field of piston housing processing technology. It includes an inspection mounting plate with an auxiliary component on one side and bolts on the surface of the inspection mounting plate near the auxiliary component. This auxiliary inspection device for piston housings uses bolts to ensure a tight connection between the housing and the inspection mounting plate, preventing warping due to uneven contact and eliminating measurement errors caused by deformation. When the limiting plate moves, it gradually moves to the side of the bolts to prevent bolt movement. When the bonding plate moves, the connecting rod connected to the bonding plate moves along the inclined T-shaped groove on the guide plate surface, gradually moving out of the groove to bring the bonding plate into contact with the housing, allowing for pressing of the housing and ensuring tight contact with the inspection mounting plate, further preventing warping of the housing.

Description

Technical Field

[0001] This utility model relates to the field of piston housing processing technology, specifically to an auxiliary testing device for piston housing. Background Technology

[0002] The trilobed structure of the piston housing serves as an "anti-rotation" function on the piston shaft in the ELSA brake assembly, making it a critical working component in the truck braking system. Therefore, the accuracy of the measurement data for the trilobed structure directly impacts the safety of the braking system. Traditional inspection methods involve fixing the piston housing workpiece in a fixture, using shape and three-point positioning to secure the workpiece, and placing it on the work platform of a coordinate measuring machine (CMM). Then, a professional CMM operator uses a handle to establish a product coordinate system and inspect the shape of the trilobed opening. The advantage of this method is its simplicity and ease of operation. The disadvantage is that it cannot eliminate measurement errors caused by product deformation. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an auxiliary detection device for piston housings. Bolts ensure a tight connection between the housing and the detection mounting plate, preventing warping caused by uneven contact and eliminating measurement errors due to deformation. The movement of the bonding plate and the limiting plate allows the limiting plate to gradually move towards the bolt, preventing bolt movement. During the movement of the bonding plate, the connecting rod connected to it moves along an inclined T-shaped groove on the guide plate surface, allowing the bonding plate to move backward as it moves downward, gradually moving out of the groove and making contact with the housing. This allows for pressing the housing and ensuring tight contact with the detection mounting plate, further preventing warping. This method solves the problem of using a professional coordinate measuring machine operator to establish a product coordinate system via a handle to detect the shape of the lobed hole. The advantages of this method are simple clamping and easy operation. The disadvantage is that it cannot eliminate measurement errors caused by product deformation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a piston housing auxiliary detection device, comprising a detection mounting plate, an auxiliary component being provided on one side of the detection mounting plate, and bolts being provided on the surface of the detection mounting plate near the auxiliary component, wherein the number of bolts is multiple, and the bolts are connected to the detection mounting plate via threads.

[0005] The auxiliary component includes two limiting plates stacked one on top of the other. Each limiting plate has a groove on its surface near the detection mounting plate, and a bonding plate is placed inside the groove. The bonding plate is in contact with the limiting plate. A horizontal bar is fixedly installed at both ends of the limiting plate. A vertical bar is installed at the end of the horizontal bar away from the limiting plate, and the bottom end of the vertical bar is fixedly connected to the detection mounting plate. A moving block is installed on the front of one end of the horizontal bar, and a connecting rod is installed on the side of the horizontal bar away from the moving block. The connecting rod is fixedly connected to the bonding plate. A guide plate is installed on the surface of the connecting rod away from the horizontal bar, and one side of the guide plate is inclined.

[0006] Preferably, the top surface of the detection mounting plate is provided with a positioning contour.

[0007] Preferably, the vertical bar has a T-shaped groove on the side surface near the horizontal bar and on one end surface of the guide plate. One end of the horizontal bar extends into the T-shaped groove of the vertical bar and is slidably connected to the T-shaped groove.

[0008] Preferably, a stop bar is fixedly provided on the top of the limiting plate, and the stop bar is located on the top of the detection mounting plate.

[0009] Preferably, a rotating rod is provided on one side of the vertical rod, and threaded rods are fixedly provided at the top and bottom of the rotating rod. The top threaded rod and the bottom threaded rod are threadedly connected to the corresponding outer moving block, and the threads on the surfaces of the top threaded rod and the bottom threaded rod are arranged in opposite directions.

[0010] Preferably, a round rod is fixedly provided on the front side of the connecting rod, the round rod passing through the crossbar and in contact with the crossbar.

[0011] Preferably, a fixing plate is provided on one side of the vertical rod, and the vertical rod is fixedly connected to the guide plate through the fixing plate. The cross-sectional shape of the fixing plate is L-shaped.

[0012] Preferably, the connecting rod is in contact with the limiting plate, and the limiting plate and the bonding plate are vertically collinear on one side surface.

[0013] Beneficial effects

[0014] This invention provides an auxiliary detection device for piston housings. Compared with the prior art, it has the following advantages:

[0015] 1. This piston housing auxiliary detection device uses bolts to ensure a tight connection between the housing and the detection mounting plate, preventing warping caused by uneven contact and eliminating measurement errors due to deformation. The movement of the bonding plate and the limiting plate allows the limiting plate to gradually move to one side of the bolt, preventing bolt movement. When the bonding plate moves, the connecting rod connected to it moves along the inclined T-shaped groove on the guide plate surface, allowing the bonding plate to move backward as it moves downward, gradually moving out of the groove and into contact with the housing. This allows for pressing of the housing and tight contact with the detection mounting plate, further preventing warping of the housing.

[0016] 2. In this piston housing auxiliary detection device, since the limiting plate is fixedly connected to the stop rod, the downward movement of the limiting plate can cause the stop rod to move downward at the same time. When the stop rod contacts the detection mounting plate, it prevents the limiting plate from continuing to move, ensuring that the limiting plate is located on the side of the bolt.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a piston housing auxiliary detection device, including a detection mounting plate 1, an auxiliary component 2 is provided on one side of the detection mounting plate 1, and a bolt 3 is provided on the surface of the detection mounting plate 1 near the auxiliary component 2. There are multiple bolts 3, and the bolts 3 are connected to the detection mounting plate 1 through threads.

[0026] The auxiliary component 2 includes two limiting plates 201 stacked one on top of the other. Each limiting plate 201 has a groove 202 on its surface near the detection mounting plate 1, and a bonding plate 208 is provided inside the groove 202. The bonding plate 208 is in contact with the limiting plate 201. A horizontal bar 203 is fixedly provided at both ends of the limiting plate 201. A vertical bar 204 is provided at the end of the horizontal bar 203 away from the limiting plate 201, and the bottom end of the vertical bar 204 is fixedly connected to the detection mounting plate 1. A moving block 205 is provided on the front of one end of the horizontal bar 203, and a connecting rod 206 is provided on the side of the horizontal bar 203 away from the moving block 205. The connecting rod 206 is fixedly connected to the bonding plate 208. A guide plate 207 is provided on the surface of the connecting rod 206 away from the horizontal bar 203, and one side of the guide plate 207 is inclined.

[0027] The top surface of the mounting plate 1 is provided with a positioning contour. A fixing plate 214 is provided on one side of the vertical rod 204. The vertical rod 204 is fixedly connected to the guide plate 207 through the fixing plate 214. The cross-sectional shape of the fixing plate 214 is L-shaped. The side surface of the vertical rod 204 near the horizontal rod 203 and the end surface of the guide plate 207 are both provided with T-shaped grooves 209. One end of the horizontal rod 203 extends into the T-shaped groove 209 of the vertical rod 204 and is slidably connected with the T-shaped groove 209. The T-shaped groove 209 on the surface of the vertical rod 204 is vertically set, which allows the subsequent moving block 205 to move in a straight line. The T-shaped groove 209 on the surface of the guide plate 207 is inclined, which facilitates the increase of the distance between the connecting rod 206 and the horizontal rod 203 when the connecting rod 206 moves along the T-shaped groove 209 on the surface of the guide plate 207.

[0028] A rotating rod 211 is provided on one side of the vertical rod 204. Threaded rods 212 are fixedly provided at the top and bottom of the rotating rod 211. The top threaded rod 212 and the bottom threaded rod 212 are threadedly connected to the corresponding outer moving block 205. The threads on the surfaces of the top threaded rod 212 and the bottom threaded rod 212 are arranged in opposite directions. The rotation of the rotating rod 211 drives the threaded rod 212 to rotate. During the rotation of the threaded rod 212, the moving block 205 can move simultaneously and can move along the T-shaped slide groove 209 at the vertical rod 204.

[0029] A round rod 213 is fixedly installed on the front of the connecting rod 206. The round rod 213 passes through the crossbar 203 and is in contact with the crossbar 203. When the connecting rod 206 moves backward, it drives the round rod 213 to move. The round rod 213 connects the connecting rod 206 and the crossbar 203 together, allowing the connecting rod 206 to move linearly. The connecting rod 206 is in contact with the limiting plate 201. The limiting plate 201 and one side surface of the bonding plate 208 are vertically collinear to prevent the bonding plate 208 from contacting the bolt 3 when it moves downward with the limiting plate 201, thus preventing it from affecting the downward movement.

[0030] Please see Figure 2 A stop bar 210 is fixedly installed on the top of the top limiting plate 201, and the stop bar 210 is located on the top of the detection mounting plate 1. By moving the limiting plate 201 downward, the stop bar 210 can move downward at the same time. When the stop bar 210 contacts the detection mounting plate 1, it prevents the limiting plate 201 from continuing to move, thus ensuring that the limiting plate 201 is located on one side of the bolt 3.

[0031] During operation, the housing is placed on one side of the detection mounting plate 1, with a portion of the housing positioned within the positioning contour. Then, bolts 3 are inserted through the housing and into the detection mounting plate 1. Since bolts 3 are threadedly connected to the detection mounting plate 1, a torque wrench is used to ensure a tight connection between the housing and the detection mounting plate 1, preventing warping due to uneven contact and eliminating measurement errors caused by deformation. After installation, the rotating rod 211 is rotated. This rotation causes both the upper and lower threaded rods 212 to rotate simultaneously. During the process, because the threads on the surfaces of the upper and lower threaded rods 212 are set in opposite directions, and the threaded rods 212 are threadedly connected to the moving block 205, the rotation of the two threaded rods 212 can cause the two moving blocks 205 to move simultaneously, moving in the direction of the rotating rod 211, and the horizontal bar 203 fixedly connected to the moving block 205 moves simultaneously. The horizontal bar 203 is slidably connected to the T-shaped groove 209 of the vertical rod 204, and can move vertically along the T-shaped groove 209. The movement of the horizontal bar 203 causes the limiting plate 201 and the bonding plate 208 to move simultaneously. This allows the limiting plate 201 to gradually move to one side of the bolt 3. Because the opposite surfaces of the bolt 3 and the limiting plate 201 are vertically collinear, the limiting plate 201 can contact the bolt 3, preventing the bolt 3 from moving. The movement of the crossbar 203 causes the round rod 213 and the connecting rod 206 to move simultaneously. When the connecting rod 206 moves, the inclined T-shaped groove 209 on the surface of the guide plate 207 slides along the connecting rod 206, allowing the connecting rod 206 to move along the T-shaped groove 209 on the surface of the guide plate 207. The T-shaped groove 209 on the surface of the guide plate 207 is inclined. When the connecting rod 206 moves towards the rotating rod 211, the distance between the connecting rod 206 and the crossbar 203 gradually increases, allowing the connecting rod 206 to move towards the housing. Simultaneously, the bonding plate 208, which is fixedly connected to the connecting rod 206, moves backward during its downward movement, gradually moving out of the groove 202. This allows the bonding plate 208 to come into contact with the housing, pressing it firmly and ensuring close contact with the detection mounting plate 1, further preventing warping of the housing and facilitating subsequent testing.
