Description

Technical Field

[0001] This invention belongs to the field of mechanical inspection and processing, and particularly relates to a method for leveling and grinding a horizontal plane. Background Technology

[0002] During the production of mechanical devices, a leveling plane needs to be ground on the connecting seat for leveling. This plane has a strict parallel relationship with the center line of the tube and is a crucial structural indicator in the mechanical device. Since the tube and connecting seat cannot be integrally formed, a threaded connection is used. Although the parallelism between the leveling plane and the internal thread of the connecting seat is strictly controlled during the machining of the connecting seat, and the parallelism between the external thread of the tube and the center line is strictly controlled during the machining of the tube, a certain error still exists after assembly. This causes the parallelism between the leveling plane of the connecting seat and the center line of the tube to exceed the product specifications.

[0003] Therefore, researching a method for grinding and testing the parallelism of the horizontal plane after the body tube and connecting seat are assembled is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] This invention provides a method for leveling and grinding a horizontal plane, which aims to solve the following problems.

[0005] This invention is implemented as follows: a method for leveling and grinding a horizontal plane, characterized in that the method comprises the following steps in sequence:

[0006] Step S1: Assemble the tube to be inspected with the connecting seat;

[0007] Step S2: Place the support fixture on the worktable;

[0008] Step S3: Place the V-shaped bracket on one side of the support clamp;

[0009] Step S4: Place the assembled connecting seat on the support fixture and the body tube on the V-shaped bracket;

[0010] Step S5: Insert the end detection post into the tube port;

[0011] Step S6: Place the first level on the base surface of the support fixture;

[0012] Step S7: Place the second level on the end detection column;

[0013] Step S8: By adding an adjusting shim between the support fixture and the worktable, the bubble of the first level is centered.

[0014] Step S9: Adjust the height of the V-shaped bracket according to the bubble offset of the first level instrument to center the bubble of the second level instrument.

[0015] Step S10: Use a grinding machine to grind the horizontal plane on the connecting seat;

[0016] Step S11: Move the first level instrument, which was originally placed on the base of the support fixture, to the level plane on the connecting seat;

[0017] Step S12: Observe the bubbles in the first and second levels. When the first and second levels are centered at the same time, it ensures that the parallelism between the leveling plane of the connecting seat and the center line of the tube meets the requirements.

[0018] Optionally, the maximum height of the V-shaped bracket is greater than the sum of the height of the workbench and the height of the support fixture.

[0019] Optionally, the end detection post and the body tube are fitted with a transition fit.

[0020] Optionally, the end of the end detection column away from the body tube has a placement plane for placing the second level.

[0021] Optionally, the surface of the placement plane of the end detection column is provided with an anti-slip rubber pad.

[0022] The beneficial technical effects of implementing the present invention are as follows: By applying the technical solution of the present invention, the horizontal condition of the support fixture and the tube is determined by using the first level and the second level respectively, and then the level plane is processed. Finally, the position of the first level is adjusted to quickly check whether the level plane meets the processing requirements, which greatly improves the calibration rate of the level plane and the debugging process before processing.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figure 1 As shown, the present invention provides a method for leveling and grinding a horizontal plane, the method comprising the following steps in sequence:

[0029] Step S1: Assemble the tube 1 to be inspected and the connecting seat 2;

[0030] Step S2: Place the support fixture 3 on the worktable 4;

[0031] Step S3: Place the V-shaped bracket 5 on one side of the support clamp 3;

[0032] Step S4: Place the assembled connecting seat 2 on the support clamp 3 and the body tube 1 on the V-shaped bracket 5;

[0033] Step S5: Insert the end detection post 6 into the port of the body tube 1;

[0034] Step S6: Place the first level 7 on the base surface of the support fixture 3;

[0035] Step S7: Place the second level 8 on the end detection column 6;

[0036] Step S8: By adding an adjusting shim 9 between the support clamp 3 and the worktable 4, the bubble of the first level 7 is centered;

[0037] Step S9: Adjust the height of the V-shaped bracket 5 according to the bubble offset of the first level instrument 7 so that the bubble of the second level instrument 8 is centered.

[0038] Step S10: Using grinding machine 10, grind the horizontal plane 201 on the connecting seat 2;

[0039] Step S11: Move the first level 7, which was originally placed on the base surface of the support fixture 3, to the level plane 201 on the connecting seat 2;

[0040] Step S12: Observe the bubbles in the first level 7 and the second level 8. When the first level 7 and the second level 8 are centered at the same time, it ensures that the parallelism between the level plane of the connecting seat and the center line of the tube meets the requirements.

[0041] Furthermore, the maximum height of the V-shaped bracket 5 is greater than the sum of the height of the workbench 4 and the height of the support fixture 3.

[0043] Furthermore, the end detection column 6 and the body tube 1 are fitted in a transitional manner.

[0044] The advantage of this embodiment is that it helps prevent the end detection column 6 from shaking relative to the body tube 1, thereby improving the measurement effect of the second level 8.

[0045] Furthermore, the end of the end detection column 6, away from the body tube 1, is provided with a placement plane for placing the second level 8.

[0046] The advantage of this embodiment is that the placement plane facilitates the placement of the second level 8.

[0047] Furthermore, the surface of the end detection column 6 is provided with an anti-slip rubber pad.

[0048] The advantage of this embodiment is that it increases the friction between the placement plane of the end detection column 6 and the second level 8, preventing the second level 8 from shaking during calibration and processing.

[0049] 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 within the protection scope of the present invention.
