[0045] Example

[0046] like Figure 1-6As shown, this embodiment provides a constant velocity universal joint assembly compression length and weight detection device, comprising: a workbench 1, a fixing device 2 arranged at one end of the workbench 1, a plurality of receiving devices 3 arranged at one side of the fixing device 2, a weight detector 4 arranged on the receiving device 3, and an extrusion device 5 arranged outside the receiving device 3. The universal joint is placed between the fixing device 2 and the extrusion device 5 and supported by the receiving device 3 to detect the assembly compression length of the universal joint, that is, the fixing device 2 is connected to one end of the universal joint, the extrusion device 5 is connected to the other end of the universal joint, and the main body of the universal joint is placed on the receiving device 3. The universal joint is compressed by moving the extrusion device 5, and then the assembly compression length of the universal joint is detected. At the same time, the weight of the universal joint is detected by the weight detector 4 to determine whether the universal joint is missed or wrongly installed, and whether the universal joint is filled with oil or less grease, etc. The whole process is simple to operate, with a high degree of automation, convenient to use, and high work efficiency.

[0047] Among them, the fixing device 2 includes: a fixing seat 21 fixedly connected to one end of the slide rail 11 of the workbench 1, and a positioning member 22 arranged on the fixing seat 21, preferably two slide rails 11, and the fixing seat 21 is arranged between the two slide rails 11. The fixing seat 21 and the positioning member 22 are used to limit the initial position of the universal joint, so that one end of the universal joint remains stationary, which facilitates the extrusion device 5 to perform an extension and retraction operation on the other end of the universal joint to complete the compression length.

[0048] At the same time, the receiving device 3 and the extrusion device 5 are sequentially installed on the slide rail 11, preferably two receiving devices 3, and the distance between the two receiving devices 3 can be adjusted accordingly according to universal joints of different sizes, so that the equipment can perform detection operations of universal joints of different sizes on the same machine, that is, the equipment can detect various types of universal joints and has a wide range of applications.

[0049] In this embodiment, the receiving device 3 includes: a support seat 31 fixedly connected to the slide rail 11 and a receiving seat 32 arranged above the support seat 31, the weight detector 4 is arranged between the fixed seat 21 and the support seat 31, the support seat 31 is used to support the weight detector 4 and the entire universal joint, and the receiving seat 32 is used to install the universal joint. The overall structure of the receiving device 3 is simple and easy to disassemble and assemble.

[0050] In this embodiment, the extrusion device 5 includes: a moving seat 51 slidably connected to the slide rail 11, a driving member 52 arranged below the moving seat 51, a screw rod 53 passing through the moving seat 51, a pulley 55 for transmitting power, and a top plate 54 fixedly connected to the moving seat 51, the two ends of the screw rod 53 extend outward respectively, one end of the pulley 55 is connected to the output end of the driving member 52, and the other end is connected to the screw rod 53, the driving member 52 provides power to drive the pulley 55 to rotate, and then drive the screw rod 53 to rotate, at this time, the moving seat 51 moves on the slide rail 11, and then drives the top plate 54 to move, so as to control the telescopic state of the universal joint, and then detect the assembly compression length of the universal joint, and the moving seat 51 can be moved automatically and pushed manually, and the combination of the two is more convenient.

[0051] In this embodiment, an indicator rod 56 is provided at the bottom end of the top plate 54, and the indicator rod 56 is arranged close to the movable seat 51. A measuring tool 12 is arranged directly below the end of the indicator rod 56, and preferably, the measuring tool 12 is arranged on the outside of the slide rail 11 for easy observation. The indicator rod 56 is used to indicate the corresponding value on the measuring tool 12, thereby manually detecting the assembly compression length of the universal joint.

[0052] Of course, a display panel 13 is provided on one side of the slide rail 11, and a console 14 is provided on one side of the display panel 13. The parameters displayed on the display panel 13 include weight, assembly compression length, etc. The start and stop of the entire equipment is controlled by the console 14, which is simple to operate and convenient to control. The weight detector 4 preferably adopts a weight sensor, which is connected to the display panel 13 to convert the mass signal into a measurable electrical signal, that is, output an electrical signal that is proportional to the weight value, and then feed it back to the display panel 13 to directly detect whether the universal joint is qualified. The universal joint only needs to be placed directly on the support seat 31, and the support seat 31 will transmit the weight signal to the weight sensor, and the weight sensor will convert the mass signal into an electrical signal and feed it back to the display panel 13. The whole process is simple to operate, easy to use, and has high detection efficiency.

[0053] In addition, the middle part of the socket 32 ​​is concave, and its shape is adapted to the appearance of the universal joint to be tested. The shape of the middle part of the socket 32 ​​must ensure that the universal joint will not separate from the socket 32, and must ensure that the assembly of the universal joint is not disturbed when testing, thereby ensuring the accuracy of the test results.

[0054] The working principle of this embodiment is: first, place the universal joint to be tested on the receiving device 3, then open the display panel 13 and the control console 14, at this time, the weight detector 4 feeds back the weight of the universal joint to the display panel 13, and then the squeezing device 5 starts to compress the universal joint. When the value on the display panel 13 is within the specified range, the universal joint is qualified. When the display panel 13 fails, the squeezing device 5 can be manually pushed. At this time, the position change of the indicator rod 56 can be observed by the measuring tool 12, and then detect whether the change in the assembly compression length of the universal joint is qualified.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
