[0002] For the finished product to be assembled as shown in Figure 1 , it is necessary to install the bearing assembly 01 into the water pump body 02. For finished products of different models, the axial position of the bearing assembly 01 in the water pump body 02 is different. In the past, the assembly method was to design a special tooling for each model. There are many toolings for assembling bearings, and the production cost and management cost are high. In addition, the pressing head of the tooling wears, and the maintenance and replacement cost are high. Based on the above defects and deficiencies, it is necessary to improve the existing technology and design a tooling structure for general assembly of bearings. Summary of the Utility Model

[0004] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a tooling structure for general assembly of bearings, which includes a pressing head body, locking columns, an adjusting sleeve, adjusting nuts, adjusting pull rods and magnets. The lower end of the pressing head body is axially threadedly connected with an adjusting sleeve. At least two locking columns are radially threadedly connected to the pressing head body. The locking columns can abut against the upper end of the adjusting sleeve. An adjusting pull rod is axially installed at the upper end of the pressing head body. The adjusting pull rod passes through the upper end of the pressing head body and is threadedly connected with an adjusting nut. A magnet is installed at the lower end of the adjusting pull rod. The outer diameter of the adjusting sleeve is smaller than the installation hole diameter of the bearing assembly on the water pump body. The adjusting sleeve is axially provided with an adjusting through hole for avoiding the bearing assembly and the adjusting pull rod.

Detailed implementation manners

[0020] The following elaborates on the preferred embodiments of the present utility model in detail with reference to the drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 , the embodiments of the present utility model include:

[0022] A tooling structure for general assembly of bearings, which includes a press head body 1, locking columns 2, an adjusting sleeve 3, an adjusting nut 4, an adjusting pull rod 5 and a magnet 6. The lower end of the press head body 1 is axially threadedly connected with the adjusting sleeve 3. At least two locking columns 2 are radially threadedly connected to the press head body 1, and the locking columns 2 can abut against the upper end of the adjusting sleeve 3. The upper end of the press head body 1 is axially equipped with an adjusting pull rod 5. The adjusting pull rod 5 passes through the upper end of the press head body 1 and is threadedly connected with an adjusting nut 4. A magnet 6 is installed at the lower end of the adjusting pull rod 5. The outer diameter of the adjusting sleeve 3 is smaller than the installation hole diameter of the bearing assembly 01 on the water pump body 02. The adjusting sleeve 3 is axially provided with an adjusting through hole 30 for avoiding the bearing assembly 01 and the adjusting pull rod 5.

[0023] The press head body 1 is axially provided with a threaded hole 11, and the adjusting sleeve 3 is threadedly connected to the threaded hole 11. The press head body 1 is radially provided with a number of transverse threaded holes 12 communicating with the threaded hole 11, and the locking columns 2 are threadedly connected to the transverse threaded holes 12. The press head body 1 is axially provided with an intermediate hole 13 communicating with the threaded hole 11, and the adjusting pull rod 5 movably passes through the intermediate hole 13; the adjusting pull rod 5 has a clearance fit with the intermediate hole 13.

[0024] The upper end of the adjusting sleeve 3 is provided with a conical surface 31, and one end of the locking column 2 close to the adjusting sleeve 3 is conical. After the position of the adjusting sleeve 3 is adjusted, the locking column 2 is rotated to adjust its horizontal installation position until the conical surface of the locking column 2 contacts and presses against the conical surface 31 of the adjusting sleeve 3, preventing the adjusting sleeve 3 from rotating during the process of pressing the bearing assembly 01.

[0025] The lower end of the adjusting pull rod 5 is provided with a receiving groove 50, and the magnet 6 is installed in the receiving groove 50.

[0026] When the tooling structure for general assembly of bearings of the present invention works, it includes the following steps:

[0027] (1). Install the water pump body 02 on the press workbench, screw the adjusting sleeve 3 into the threaded hole 11 of the press head body 1, and adjust the distance from the lower end face of the adjusting sleeve 3 to the lower end face of the press head body 1 according to the position of the bearing assembly 01 required in the water pump body 02;

[0028] (2). Install two locking columns 2 into the corresponding transverse threaded holes 12 of the press head body 1 and lock them, so that the conical surface of the locking column 2 contacts and presses against the conical surface 31 of the adjusting sleeve 3, preventing the adjusting sleeve 3 from rotating;

[0029] (3). Install the magnet 6 into the receiving groove 50 at the lower end of the adjusting pull rod 5, pass the adjusting pull rod 5 through the intermediate hole 13 from the lower end of the press head body 1, and lock it with the adjusting nut 4;

[0030] (4) Install the upper end of the bearing assembly 01 into the adjustment through-hole 30 of the adjusting sleeve 3. By adjusting the adjusting nut 4, the distance between the lower end face of the magnet 6 and the upper end of the bearing assembly 01 can be adjusted to ensure that the magnet 6 attracts the bearing assembly 01 and prevents it from falling;

[0031] (5) Fix the upper end of the press head body 1 with the bearing assembly 01 to the press head of the press;

[0032] (6) Start the press. The press head body 1 moves downward, and the outer circle of the bearing assembly 01 is pressed into the inner hole of the water pump body 02 until the lower end face of the press head body 1 contacts the upper end face of the water pump body 02 and then stops moving downward;

[0033] (7) The press rises, driving the press head body 1 to rise. Since the magnet 6 cannot generate the combined weight of the bearing assembly 01 and the water pump body 02, it disengages from the upper end face of the bearing assembly 01;

[0034] (8) Remove the water pump body 02 with the installed bearing assembly 01, place a new water pump body 02 again, place the new bearing assembly 01 into the inner hole of the press head body 1 and attract it with the magnet 6, and repeat the above steps (6) and (7) to complete 1 more assembly cycle.

[0035] The tooling structure for generally assembling bearings of the present utility model ensures that the bearing assembly is reliably adsorbed at the top of the press head, avoids clamping design, and has a simple and reliable structure; the axial position of the adjusting sleeve can be adjusted to meet the requirements of different assembly heights, avoiding the design of a fixed-size press head for each model, saving costs and having high efficiency.

[0036] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the description and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
