Description
Technical Field
[0001] This utility model relates to the field of mechanical assembly technology, and to an installation device for an irregular cylindrical workpiece and an elastic sleeve. Background Technology
[0002] Traditional elastic sleeve (EVA, NBR materials) assembly mainly includes two methods: manual fitting after applying lubricant and radial expansion assembly using mechanical grippers. The former has low production efficiency and is prone to sleeve breakage, with a pass rate of only 85% and a time consumption of 3-5 minutes per piece; the latter has a complex structure, high cost, and poor adaptability, making it difficult to meet the high-precision assembly requirements of irregularly shaped cylindrical workpieces (the diameter of the cylinders at both ends is larger than that of the middle cylinder), and it is also prone to sleeve breakage. Utility Model Content
[0003] To address the technical problems in the prior art, this utility model provides an installation device for an irregularly shaped cylindrical workpiece and an elastic sleeve, comprising a frame, an upper platform at the top of the frame, and a lower platform at one end of the frame near the bottom. An installation plate is fixedly installed between the lower platform and the upper platform. A cylinder is fixedly installed on the installation plate via a bracket, and the telescopic rod of the cylinder slides through the upper platform. The device also includes a support base for placing the irregularly shaped cylindrical workpiece, an air pipe assembly, and an inflation head. The support base is fixedly connected to the telescopic rod of the cylinder and moves up and down under the action of the cylinder. The inflation head is detachably installed at one end of the irregularly shaped cylindrical workpiece near the top and communicates with the interior of the elastic sleeve. The inflation head and the cylinder are connected to an air source via the air pipe assembly. The elastic sleeve expands under the inflation action of the inflation head and engages with the irregularly shaped cylindrical workpiece under the action of the cylinder.
[0004] Furthermore, an upper limit block and a lower limit block are fixedly installed on the bracket, and a connecting block is fixedly installed on the telescopic rod of the cylinder. When the connecting block contacts the lower limit block or the upper limit block, the irregular cylindrical workpiece is fixed relative to the upper platform.
[0005] Furthermore, when the connecting block contacts the lower limit block, the elastic sleeve is sleeved on the top of the irregular cylindrical workpiece under the action of external force; when the connecting block contacts the upper limit block, the elastic sleeve cooperates with the irregular cylindrical workpiece.
[0006] Furthermore, the air hose assembly includes a main air hose quick connector, an air inlet pipe, an air hose tee, a single-way solenoid valve, an air blowing pipe, a two-position five-way bidirectional control solenoid valve, and a cylinder air inlet pipe. One end of the air inlet pipe is connected to the air source through the main air hose quick connector, and the other end is connected to the first interface of the air hose tee. The air inlet of the single-way solenoid valve is connected to the second interface of the air hose tee, and the air outlet of the single-way solenoid valve is connected to the inflation head through the air blowing pipe. The air inlet of the two-position five-way bidirectional control solenoid valve is connected to the third interface of the air hose tee, and the air outlet of the two-position five-way bidirectional control solenoid valve is connected to both the air inlet and air outlet of the cylinder through the cylinder air inlet pipe.
[0007] Furthermore, the bottom of the frame is equipped with casters.
[0008] Furthermore, the end of the inflation head that communicates with the interior of the elastic sleeve is a pointed tip.
[0009] Beneficial effects: 1. In this utility model, by setting up a cylinder, support base, air pipe assembly and air inflator, non-destructive assembly of irregular cylindrical workpieces can be achieved by gas expansion and cylinder assembly, which improves production and installation efficiency and effectively avoids the problem of elastic sleeve breakage. The specific process is as follows: First, insert the elastic sleeve into the front quarter of the irregular cylindrical workpiece (because the elastic sleeve has contractibility, it can only be inserted to a quarter depth by hand). Then, place the irregular cylindrical workpiece with the elastic sleeve on the support base. Next, insert the inflation head into the elastic sleeve, hold the elastic sleeve and inflation head with your hand to prevent air leakage, and inject compressed air into the elastic sleeve through the air pipe assembly to make the elastic sleeve expand. After an automatic 1-second delay, the cylinder is started by controlling the air pipe assembly, which causes the telescopic rod to move the irregular cylindrical workpiece placed on the support base upward. At this time, use your other hand to easily hold the elastic sleeve and pull it downward. Because the inner diameter of the elastic sleeve will increase after the air is injected and it expands, and the elastic sleeve and the irregular cylindrical workpiece are in a state of moving towards each other, the elastic sleeve can be successfully installed into the interior of the irregular cylindrical workpiece.
[0010] 2. In this utility model, the upper limit block and the lower limit block are used to limit the movement of the telescopic rod. When the connecting block contacts the lower limit block, the elastic sleeve is sleeved on the top of the irregular cylindrical workpiece under the action of external force. When the connecting block contacts the upper limit block, the elastic sleeve cooperates with the irregular cylindrical workpiece. This arrangement ensures that when the telescopic rod moves to the limit position, the elastic sleeve and the irregular cylindrical workpiece can be perfectly installed and cooperated.
[0011] 3. In this utility model, the main air pipe quick connector, air inlet pipe, air pipe tee, single-way solenoid valve, air blowing pipe, two-position five-way bidirectional control solenoid valve and cylinder air inlet pipe are set up to facilitate the linkage control of the air filling head and cylinder, and further improve the production and installation efficiency under the premise of optimizing the equipment structure. The specific process is as follows: After connecting to the air source via the main air pipe quick connector, sufficient air is filled into the air intake pipe. The equipment is started through the internal control system, and the single-way solenoid valve is opened first to allow compressed air to reach the inflation head through the air blowing pipe and blow out compressed air, causing the elastic sleeve to expand. After an automatic delay of 1 second, the two-position five-way bidirectional control solenoid valve is controlled to inflate / de-inflate the cylinder, causing the cylinder's extension rod to move the support seat upward. When the cylinder extension rod reaches its limit position and contacts the upper limit block, it stops moving upward, completing the assembly of the elastic sleeve. After a delay of 2 seconds, the cylinder extension rod moves downward. When the cylinder extension rod reaches its limit position and contacts the lower limit block, it stops moving downward, and the two-position five-way bidirectional control solenoid valve is de-energized to stop the cylinder. The single-way solenoid valve is disconnected to stop the inflation head from blowing air, thus completing one up / down movement cycle.
[0012] 4. The movable casters in this utility model facilitate the movement and transportation of the frame; the pointed end allows the inflation head to be easily inserted into the elastic sleeve for inflation. Attached Figure Description

[0022] This utility model provides an installation device for an irregularly shaped cylindrical workpiece and an elastic sleeve, such as... Figure 1 , Figure 2 and Figure 3 As shown, the system includes a frame 1, which is specifically assembled from multiple aluminum alloy columns. The top of the frame 1 is provided with an upper platform 2, and the bottom end of the frame 1 is provided with a lower platform 3. An installation plate 4 is fixedly installed between the lower platform 3 and the upper platform 2. A cylinder 6 is fixedly installed on the installation plate 4 through a bracket 5, and the telescopic rod of the cylinder 6 slides through the upper platform 2. The system also includes a support base 8 for placing an irregular cylindrical workpiece 7, an air pipe assembly, and an inflation head 9. The support base 8 is fixedly connected to the telescopic rod of the cylinder 6 and moves up and down under the action of the cylinder 6. The inflation head 9 is detachably installed at the top end of the irregular cylindrical workpiece 7 and communicates with the interior of an elastic sleeve 10. The inflation head 9 and the cylinder 6 are connected to an air source through the air pipe assembly, where the air source can be an air compressor. The elastic sleeve 10 expands under the inflation action of the inflation head 9 and cooperates with the irregular cylindrical workpiece 7 under the action of the cylinder 6.
[0023] In this embodiment, by setting up cylinder 6, support base 8, air pipe assembly and inflation head 9, non-destructive assembly of irregular cylindrical workpiece 7 can be achieved by gas expansion and cylinder 6 assembly, which improves production and installation efficiency and effectively avoids the problem of elastic sleeve 10 breaking. The specific process is as follows: First, insert the elastic sleeve 10 into the front quarter of the irregular cylindrical workpiece 7 (because the elastic sleeve 10 has contractibility, it can only be inserted to a quarter depth by manual means). Then, place the irregular cylindrical workpiece 7 with the elastic sleeve 10 on the support base 8. Next, insert the inflation head 9 into the elastic sleeve 10. Hold the elastic sleeve 10 and the inflation head 9 with your hand to prevent air leakage. After the air pipe assembly injects compressed air into the elastic sleeve 10, the elastic sleeve 10 expands. After an automatic 1-second delay, the air pipe assembly controls the cylinder 6 to start, causing the telescopic rod to move the irregular cylindrical workpiece 7 placed on the support base 8 upward. At this time, use your other hand to easily hold the elastic sleeve 10 and pull it downward. Because the inner diameter of the elastic sleeve 10 will increase after it expands due to the air injection, and the elastic sleeve 10 and the irregular cylindrical workpiece 7 are in a state of moving towards each other, the elastic sleeve 10 can be successfully installed into the interior of the irregular cylindrical workpiece 7.
[0024] In this utility model, preferably, such as Figure 2 and Figure 3 As shown, an upper limit block and a lower limit block are fixedly installed on the bracket 5, and a connecting block is fixedly installed on the telescopic rod of the cylinder 6. When the connecting block contacts the lower limit block or the upper limit block, the irregular cylindrical workpiece 7 is fixed relative to the upper platform 2. When the connecting block contacts the lower limit block, the elastic sleeve 10 is sleeved with the top of the irregular cylindrical workpiece 7 under the action of external force. When the connecting block contacts the upper limit block, the elastic sleeve 10 cooperates with the irregular cylindrical workpiece 7.
[0025] In this embodiment, the upper and lower limit blocks restrict the movement of the telescopic rod. When the connecting block contacts the lower limit block, the elastic sleeve 10 engages with the top of the irregular cylindrical workpiece 7 under external force. When the connecting block contacts the upper limit block, the elastic sleeve 10 cooperates with the irregular cylindrical workpiece 7. This arrangement ensures that when the telescopic rod moves to its limit position, the elastic sleeve 10 and the irregular cylindrical workpiece can be perfectly installed and fitted.
[0026] In this utility model, preferably, such as Figure 2 and Figure 3As shown, the air hose assembly includes a main air hose quick connector 11, an air inlet pipe 12, an air hose tee 13, a single-way solenoid valve 14, an air blowing pipe 15, a two-position five-way bidirectional control solenoid valve 16, and a cylinder air inlet pipe 17. One end of the air inlet pipe 12 is connected to the air source through the main air hose quick connector 11, and the other end is connected to the first interface of the air hose tee 13. The air inlet of the single-way solenoid valve 14 is connected to the second interface of the air hose tee 13, and the air outlet of the single-way solenoid valve 14 is connected to the inflation head 9 through the air blowing pipe 15. The air inlet of the two-position five-way bidirectional control solenoid valve 16 is connected to the third interface of the air hose tee 13, and the air outlet of the two-position five-way bidirectional control solenoid valve 16 is connected to both the air inlet and air outlet of the cylinder 6 through the cylinder air inlet pipe 17.
[0027] In this embodiment, the setup of the main air pipe quick connector 11, air inlet pipe 12, air pipe tee 13, single-way solenoid valve 14, air blowing pipe 15, two-position five-way bidirectional control solenoid valve 16, and cylinder air inlet pipe 17 facilitates the linkage control of the inflation head 9 and cylinder 6, further improving production and installation efficiency while optimizing the equipment structure. Specifically, after connecting the main air pipe quick connector 11 to the air source, sufficient air is ensured in the air inlet pipe 12. Through the internal control system, the equipment is started, and the single-way solenoid valve 14 is first opened to allow compressed air to reach the inflation head 9 through the air blowing pipe 15, causing the elastic sleeve 10 to expand. After an automatic 1-second delay, the two-position five-way bidirectional control solenoid valve 16 is controlled to inflate / de-inflate the cylinder 6, causing the cylinder 6's extension rod to move the support base 8 upwards. When the cylinder 6's extension rod reaches its limit position, such as contacting the upper limit block, the upward movement stops. At this point, the assembly of the elastic sleeve 10 is completed. After a 2-second delay, the telescopic rod of cylinder 6 moves downward. When the telescopic rod of cylinder 6 reaches its limit position and contacts the lower limit block, it stops moving downward and controls the two-position five-way bidirectional control solenoid valve 16 to de-energize, stopping cylinder 6. It also disconnects the one-way solenoid valve 14, stopping the inflation head 9 from blowing air. This completes one up / down movement cycle. The internal control system includes a PLC controller 19, a stop button 20, a start button 21, a switch button mounting box 22, and a foot valve 23. The controller 19 and the switch / button mounting box 22 are both mounted on the mounting plate 4. The stop button 20 and start button 21 are mounted on the switch / button mounting box 22. The foot valve 23 is placed on the ground for easy foot use. The stop button 20, start button 21, and foot valve 23 are all connected to the signal input port of the PLC controller 19 via control lines. Specifically, pressing the start button 21 starts the equipment. When the foot valve 23 is pressed, the PLC controller 19 receives a signal and controls the solenoid valve to open. After 1 second of inflation, the PLC controller... The device 19 controls the two-position five-way bidirectional control solenoid valve 16 to inflate or deflate the cylinder 6, causing the support base 8 to move upward. When it reaches the upper limit position, it delays for 2 seconds to control the cylinder 6 and drive the support base 8 to move downward to the limit position. The PLC controller 19 receives the signal and controls the two-position five-way bidirectional control solenoid valve 16 to de-energize and stop the cylinder 6. After releasing the foot valve 23, the air inlet 9 stops blowing air. Only by pressing the foot valve 23 again will the air inlet 9 blow out compressed air. When the stop button 20 is pressed, the equipment stops running. At this time, pressing the foot valve 23 has no effect.
[0028] In this utility model, preferably, such as Figure 1 As shown, the bottom of the frame 1 is provided with movable casters 18.
[0029] In this embodiment, the movable casters 18 facilitate the movement and transportation of the frame 1.
[0030] In this utility model, preferably, such as Figure 2 and Figure 3 As shown, the end of the inflation head 9 that is connected to the inside of the elastic sleeve 10 is a pointed end. The inflation head 9 is made of a rigid material and its surface can be covered with a flexible material, which facilitates the cooperation between the inflation head 9 and the elastic sleeve 10 while avoiding damage to the elastic sleeve 10.
[0031] In this embodiment, the pointed tip design facilitates the insertion of the inflation head 9 into the elastic sleeve 10, making it easier to inflate the interior.
[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0033] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
