Description

Technical Field

[0001] The invention relates to the technical field of hydraulic equipment, in particular to a spherical surface processing device based on an internal grinder. Background Art

[0002] The oil separator spherical surface processing work in the company is completed by the original old equipment. With the expansion of the market, the demand for oil separator spherical surface processing is increasing. The processing capacity of the existing equipment seriously limits the output of this product. In addition, the existing equipment is old and often breaks down.

[0003] In order to ensure output and product quality, it is imperative to solve the problem of limited production capacity of the original old equipment. However, after evaluation, it was found that the cost of purchasing new equipment is too high. Therefore, it is evaluated whether other existing equipment can be modified to meet the needs of spherical processing.

[0004] After research, it was found that the inner circle grinding tool is similar to the spherical surface processing equipment, so the transformation research on the inner circle grinding tool was carried out.

[0005] The characteristics of spherical machining determine the structural differences between spherical machining equipment and ordinary internal cylindrical grinding tools. Spherical grinding tools mainly bear axial forces while ordinary internal cylindrical grinding tools mainly bear radial forces. How to transform and upgrade ordinary internal cylindrical grinding tools to meet spherical machining is a key issue to be solved. Summary of the invention

[0006] The purpose of the present invention is to provide a spherical surface processing device based on an internal cylindrical grinder. The present invention is improved on the basis of the original internal cylindrical grinding tool, and has the advantages of being able to meet the spherical surface processing requirements and having a relatively low cost.

[0007] The technical solution of the present invention: a spherical processing device based on an internal cylindrical grinder, comprising a seat body, a shaft body arranged in the seat body, a pulley located on the outside of the left side of the seat body and linked with the shaft body, a spherical bearing and a disc spring arranged on the left side of the seat body; a disc spring support seat is provided on the front side of the disc spring, and a disc spring retaining ring is provided on the rear side; the disc spring support seat is in a T-stage shape, and one side of the disc spring support seat abuts against the spherical bearing, and the other side abuts against the shaft body.

[0008] In the aforementioned spherical surface processing device based on an internal cylindrical grinder, the spherical bearing is NSK7208CDF.

[0009] In the aforementioned spherical surface processing device based on an internal cylindrical grinder, an outer bearing spacer located outside and an inner bearing spacer located inside are correspondingly provided on the right side of the seat body.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] By improving the original inner circle grinding tool and using spherical bearings, disc springs and corresponding disc spring support seats instead, the original inner circle grinding tool can be used for spherical surface processing, and its processing accuracy meets the requirements;

[0012] By adopting this application, there is no need to purchase new spherical surface processing equipment. It is only necessary to upgrade and transform the original internal cylindrical grinding tool equipment and put it into the spherical surface processing production of the oil separator, which greatly reduces the equipment cost and improves the utilization rate of the old equipment.

[0013] Therefore, the present invention is improved on the basis of the original inner circle grinding tool, and has the advantages of being able to meet the requirements of spherical surface processing and having a relatively low cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0019] Embodiment. A spherical surface processing device based on an internal grinding machine, such as Figure 1 , 2 As shown, it includes a seat body 1, a shaft body 2 arranged in the seat body 1, a pulley 8 located on the outside of the left side of the seat body 1 and linked with the shaft body 2, a spherical bearing 7 and a disc spring 4 arranged on the left side of the seat body 1; the disc spring 4 is provided with a disc spring support seat 6 on the front side and a disc spring retaining ring 5 on the rear side; the disc spring support seat 6 is T-stage shaped, and one side of the disc spring support seat 6 abuts against the spherical bearing 7, and the other side abuts against the shaft body 2.

[0020] The spherical bearing 7 is NSK7208CDF.

[0021] The right side of the seat body 1 is correspondingly provided with an outer bearing spacer 31 located outside and an inner bearing spacer 32 located inside.

[0022] The structure of the existing internal grinding tool is as follows Figure 3As shown, it includes a seat body 1, a shaft body 2, a bearing outer spacer 31, a bearing inner spacer 32, a spring 41, a retaining ring 51, a support seat 61, a circular grinding bearing 71 and a pulley 8, wherein the circular grinding bearing 71 is a HRB36208 light bearing, and the spring 41 is a cylindrical compression spring.

[0023] Internal grinding tools are mainly used to process hole parts. HRB36208 light bearings DT are used at both ends for assembly. However, its light weight, high speed and low axial anti-vibration characteristics are not suitable for the technical requirements of end face grinding.

[0024] The inner circle grinding tool is pre-tightened by nuts at both ends and the dimension chain is closed. The temperature rise compensation is achieved by the self-reset of 8 groups of 7X20 cylindrical compression springs at the rear end of the grinding tool. The spring 41 is prone to fatigue deformation under frequent alternating pressure.

[0025] How to install this application

[0026] After measuring the highest runout point of the bearing and the runout point of the mold mandrel on the deflection meter, mark them; use the error cancellation method to reduce or offset the influence of the bearing on the center of rotation of the mandrel; the bearing is hot-assembled to reduce damage, and a bearing heater can be used; if conditions are not met, oil heating can also be used, and the oil temperature should be controlled at around 60 degrees, and the insulation time should be no less than 20 minutes;

[0027] After the bearing assembly is installed into the mold sleeve, turn the mandrel slowly by hand at a low speed. There should be no stagnation or jamming. When the rapid rotation stops, it should be smooth without inertia.

[0028] Too tight or too loose preload of the bearing will have a great impact on its service life and accuracy;

[0029] During the assembly process, it is allowed to use an assembly bakelite hammer to vibrate and knock the outer cylinder of the mold to release the assembly stress of the bearing and disc spring.
