Description

Technical Field

[0001] The utility model relates to the technical field of piston pin detection tooling, in particular to a piston pin size detection tooling. Background Art

[0002] With the rapid development of industrial manufacturing technology, piston pins are important connecting components in key components such as automobiles, engineering machinery and powertrains. Their dimensional accuracy and detection efficiency are of vital importance to ensuring product quality and improving production efficiency. In the manufacturing and testing process of piston pins, traditional piston pin dimensional detection mostly adopts manual measurement and comparison methods. This method not only has low detection efficiency, but is also easily affected by human factors, resulting in the inability to guarantee the accuracy of the measurement results. In addition, traditional manual detection methods have gradually failed to meet the modern manufacturing industry's demand for high efficiency.

[0003] At present, in order to achieve a relatively efficient detection effect, corresponding detection tools are usually installed on the detection equipment to assist the staff in the detection operation. However, when using most piston pin size detection tools, it is necessary to manually put the piston pins in for detection one by one, and then remove them one by one after the detection is completed. This process is relatively time-consuming and has the defect of not being able to push and unload materials at the same time, which will affect the detection efficiency and bring inconvenience to users. In view of this, we propose a piston pin size detection tool. Utility Model Content

[0004] The purpose of the utility model is to provide a piston pin size detection tool to solve the defects mentioned in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A piston pin size detection tool comprises a placement box, an arc-shaped sleeve is fixedly installed on the bottom plate of the placement box, a placement hole whose top is connected to the outside is arranged in the arc-shaped sleeve, a front frame is fixedly installed on the side of the arc-shaped sleeve, an end plate is fixedly installed on the end plate of the front frame, a first cylinder is fixedly installed on the front side of the end plate, a plug-in boss is arranged on the telescopic shaft of the first cylinder, a limit plate is fixedly installed on the side of the end plate, the plug-in boss passes through the limit plate and is slidably connected with the limit plate, the plug-in boss is located directly in front of the arc-shaped sleeve, a second cylinder is fixedly installed on the rear side of the placement box, a pushing column is arranged on the telescopic shaft of the second cylinder, the pushing column is located in the arc-shaped sleeve and is slidably connected with the arc-shaped sleeve.

[0007] Preferably, an end baffle is fixedly mounted on the inner wall of the box body at the rear end of the placement box, and the end baffle is located above the arc sleeve, which has the effect of blocking the piston pin from entering the placement hole only from the front side of the pushing column.

[0008] Preferably, inclined surfaces are provided on the left and right groove walls of the placement box, and the inclined surfaces are located on the front side of the end baffle, and the inclined surfaces are used for the piston pin to slide into the placement hole.

[0009] Preferably, a feed frame is fixedly mounted on the top surface of a plate on one side of the placement box, and the feed frame is used for the entry operation of the piston pin.

[0010] Preferably, the limiting plate is provided with a guide hole, and the plug-in boss passes through the guide hole and is slidably connected with the guide hole, so that the plug-in boss can slide back and forth normally.

[0011] Preferably, a fixing plate is fixedly mounted on the end of the telescopic shaft of the first cylinder, and the plug-in boss is fixedly mounted on the side of the fixing plate, so as to facilitate the fixing and mounting operation of the plug-in boss.

[0012] Preferably, a screw plate is fixedly mounted on the end of the telescopic shaft of the second cylinder, and the push column is fixedly mounted on the side of the screw plate, so as to facilitate the fixed mounting operation of the push column.

[0013] Preferably, a plug-in groove is provided on the side surface of the end baffle plate, and a top inclined plate is fixedly installed on the top surface of the pushing column. The top inclined plate is slidably connected to the plug-in groove, and the top inclined plate is used to prevent the piston pin from sliding to the rear side of the pushing column when the pushing column slides outward.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model provides an arc-shaped sleeve for placing a piston pin whose outer diameter meets the size. In addition, after the piston pin is placed in, the second cylinder works to drive the pushing column to move forward, so that the piston pin is pushed to be sleeved on the plug-in boss. The piston pin whose inner diameter meets the size can be normally sleeved on the plug-in boss, and the piston pin whose inner diameter is too small cannot be sleeved on the plug-in boss, so as to realize the size detection operation. In addition, after the piston pin sleeved on the plug-in boss moves backward with the plug-in boss, the piston pin sleeved on the plug-in boss can be pushed off the plug-in boss under the blocking effect of the limit plate, so as to complete the unloading operation, thereby achieving the effect of pushing and detecting at the same time and detecting unloading, which is convenient to use.

[0016] 2. The utility model is provided with a top inclined plate, which can ensure that as the push column moves forward, the top inclined plate is blocked at the inclined surface. At this time, the top inclined plate can prevent the piston pin on the inclined surface from continuing to fall into the placement hole, so that only one piston pin can be inspected in a single inspection operation, avoiding errors caused by excessive number of inspections.

[0027] Specifically, a front frame 2 is fixedly installed on the side of the arc sleeve 10, an end plate 20 is fixedly installed on the end plate body of the front frame 2, a first cylinder 23 is fixedly installed on the front side of the end plate 20, a plug-in boss 25 is arranged on the telescopic shaft of the first cylinder 23, a limiting plate 21 is fixedly installed on the side of the end plate 20, the plug-in boss 25 passes through the limiting plate 21 and is slidably connected with the limiting plate 21, the plug-in boss 25 is located directly in front of the arc sleeve 10, a second cylinder 3 is fixedly installed on the rear side of the placement box 1, a pushing column 31 is arranged on the telescopic shaft of the second cylinder 3, the pushing column 31 is located in the arc sleeve 10 and is slidably connected with the arc sleeve 10, so that the piston pin is pushed by the pushing column 31 to be sleeved on the plug-in boss 25 to realize the inner diameter detection operation, and the piston pin with too small inner diameter cannot be sleeved on the plug-in boss 25, thereby completing the inner diameter detection operation.

[0028] In this embodiment, an end baffle 12 is fixedly installed on the inner wall of the rear end box body of the placement box 1. The end baffle 12 is located above the arc sleeve 10, which has the effect of blocking the piston pin from entering the placement hole 11 only from the front side of the pushing column 31.

[0029] Specifically, inclined surfaces 13 are provided on the left and right groove walls of the placement box 1. The inclined surfaces 13 are located in front of the end baffle 12. The inclined surfaces 13 are used for the piston pin to slide into the placement hole 11, making feeding more convenient.

[0030] Furthermore, a feed frame 14 is fixedly mounted on the top surface of a plate on one side of the placement box 1, and the feed frame 14 is used for the entry operation of the piston pin.

[0031] In addition, a guide hole 22 is provided on the limit plate 21, and the plug-in boss 25 passes through the guide hole 22 and is slidably connected with the guide hole 22, so that the plug-in boss 25 can slide back and forth normally. As the plug-in boss 25 slides backward, the piston pin sleeved on the plug-in boss 25 can fall off the plug-in boss 25 under the blocking action of the limit plate 21, thereby completing the unloading operation.

[0032] It is worth mentioning that a fixed plate 24 is fixedly installed at the end of the telescopic shaft of the first cylinder 23, and the plug-in boss 25 is fixedly installed on the side of the fixed plate 24, which is convenient for fixing and installing the plug-in boss 25; a screw plate 30 is fixedly installed at the end of the telescopic shaft of the second cylinder 3, and a pushing column 31 is fixedly installed on the side of the screw plate 30, which is convenient for fixing and installing the pushing column 31.
