[0002] The constant velocity drive shaft needs to be equipped with a dust cover to prevent the entry of mud, water, dust, etc. during vehicle operation. Currently, the constant velocity drive shaft and the dust cover are assembled mainly by manual pressing and press-fitting by operators without pressure monitoring. This has the following defects:

[0003] 1. Pressing is done by touching the pressing surface with fingers, which can easily make operators feel tired during long periods of production.

[0004] 2. The efficiency of press-fitting varies among different operators, and the press-fitting process is not standardized, which makes the production rhythm unstable;

[0005] 3. Pressure monitoring was not performed after press-fitting, and the dust cover was not pressed into place, resulting in poor dust-proof effect of the constant velocity drive shaft. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a tool with pressure monitoring for quickly pressing the dust cover of the constant speed drive shaft, so as to solve the problem of hand fatigue of personnel; standardize the operation to stabilize the production rhythm; and be able to promptly detect whether the dust cover is pressed into place.

The positioning ring assembly is pressed down by the press-fitting equipment so that each presser foot assembly presses the corresponding force position on the dust cover, thereby press-fitting the dust cover and the bell housing.

[0012] As a further technical solution, the presser foot assembly includes a pressure rod whose upper end is fixed to the positioning ring assembly, a limiting pressure sleeve is provided on the lower end of the pressure rod, and two sliding grooves are opened on the outer wall of the limiting pressure sleeve. The limiting pin passes through one of the sliding grooves and then passes through the pressure rod and comes out from the other sliding groove, thereby limiting the downward movement of the limiting pressure sleeve.

[0013] As a further technical solution, a sensor and a spring are installed in the inner cavity of the limiting pressure sleeve, and the sensor is pushed against the lower end of the pressure rod by the spring.

[0014] As a further technical solution, the piston rod of the cylinder is fixed to one end of the connecting sleeve, and the other end of the connecting sleeve is sleeved on the connecting rod.

DETAILED DESCRIPTION

[0027] The following is a detailed introduction to the present invention with reference to the accompanying drawings:

[0028] Example: As shown in the attached Figures 1 to 6 As shown, this tooling with pressure monitoring and quick press-fitting of a constant velocity drive shaft dust cover comprises a presser foot assembly 1, a fixed half ring 2, a movable half ring 3, a connecting rod 4, a cylinder 5, a pressure rod 6, a limit pin 7, a sensor 8, a limit pressure sleeve 9, a pressure monitoring device 10, a dust cover 11, a bell housing 12, a force position 13, a connecting sleeve 14, a slide groove 15, a spring 16, an inner cavity 17 and a hinge pin 18.

[0029] Reference Attachment Figure 1 、 2 The positioning ring assembly includes a fixed half ring 2 and a movable half ring 3 hinged on the fixed half ring 2. A connecting rod 4 is provided on the movable half ring 3. The fixed half ring 2 and the movable half ring 3 are hinged by a hinge pin 18. The piston rod of the cylinder 5 is fixed to one end of the connecting sleeve 14, and the other end of the connecting sleeve 14 is sleeved on the connecting rod 4. The cylinder connection drives the connecting rod 4, thereby controlling the opening and closing of the movable half ring 3 relative to the fixed half ring 2.

[0030] Three presser foot assemblies 1 are installed at the bottom of the positioning ring assembly, two of which are installed on the fixed half ring 2 and the other is installed on the movable half ring 3. Figure 3 As shown, the presser foot assembly 1 includes a pressure rod 6 whose upper end is fixed to the positioning ring assembly (fixed half ring 2, movable half ring 3) by bolt connection, and a limit pressure sleeve 9 is set on the lower end of each pressure rod 6. The limit pressure sleeve 9 is provided with an inner cavity 17, and the inner cavity 17 is installed with a sensor 8 and a spring 16. Two slide grooves 15 are opened on the outer wall of the limit pressure sleeve 9 (the slide grooves 15 are connected with the inner cavity 17), and the limit pin 7 passes through one of the slide grooves 15 and then passes through the pressure rod 6 and comes out from the other slide groove 15, thereby limiting the downward movement of the limit pressure sleeve 9 (as shown in FIG. Figure 1 、 3 Furthermore, the limiting pressing sleeve 9 presses the sensor 8 against the lower end of the pressing rod 6 via the spring 16. The sensor 8 communicates with the pressure monitoring device 10 via an electrical connection, thereby transmitting a pressing force signal applied to the presser foot assembly 1 in real time. The pressure monitoring device 10 displays the pressing force value in real time, which can visually and quantitatively indicate whether the dust cover 11 is pressed into place.

[0031] like Figure 4 、 5As shown in , 6, the dust cover 11 is placed into the positioning ring assembly during press-fitting, and the dust cover 11 is pressed by hand in advance to leave three force-bearing positions 13 on the dust cover 11 (i.e., the support points of the limiting pressing sleeve 9). The positioning ring assembly is pressed down by the press-fitting equipment so that each presser foot assembly 1 corresponds to the force-bearing position 13 on the dust cover 11, thereby completing the press-fitting of the dust cover 11 and the bell-shaped shell 12.

[0032] The working process of this utility model:

[0033] 1. Install the tool on the pressing equipment (press) and turn on the pressure monitoring device 10;

[0034] 2. Start the cylinder 5 to drive the connecting sleeve 14 and the connecting rod 4, thereby opening the movable half ring 3 and placing the dust cover 11 and the bell housing 12 into the positioning ring assembly;

[0035] 3. Press the dust cover 11 by hand to press out three force-bearing positions 13, and place the presser foot assembly 1 (limiting pressing sleeve 9) on the force-bearing positions 13 of the dust cover 11;

[0036] 4. Start the cylinder 5 again to close the moving half ring 3;

[0037] 5. Start the press-fitting equipment to press-fit the dust cover, and read the pressure value on the pressure monitoring device 10. If it is not within the set parameter range, an alarm will be issued, indicating that the press-fitting is not in place;

[0038] 6. After the pressing is completed, open the movable half ring 3 and take out the product.

[0039] It is understandable that for those skilled in the art, any equivalent replacement or change of the technical solution and the concept of the utility model should fall within the scope of protection of the claims attached to the utility model.
