Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] To achieve rapid clamping of the spindle box, the first aspect of this utility model discloses a spindle box clamping fixture. For example... Figure 1 As shown, the tooling includes a machining base 1 and clamping components, limiting components, and support components, all mounted on the machining base. The clamping components clamp the guide rails on both sides of the spindle box; the limiting components and support components clamp the ends of the spindle box from both ends.

[0025] Specifically, such as Figure 1 As shown, the clamping assembly includes a first support base and a second support base 22. The second support base 22 has an L-shaped support surface, which is used to support and limit the guide rail on one side of the spindle box. The first support base includes a base 211, a clamping plate 212 fixed on the base 211, and a first adjusting bolt 213 disposed on the clamping plate 212 for cooperating with the second support base 22 to clamp the spindle box from both side guide rails. The guide rail 51 on the other side of the spindle box 5 is placed on the base 211 and there is a gap between it and the clamping plate 212. By adjusting the first adjusting bolt 213, the end of the first adjusting bolt 213 presses against the side guide rail and cooperates with the second support base 22 to clamp the spindle box.

[0026] It should be noted that, Figure 1 The dashed line represents the spindle box, and the solid line represents the tooling in this design.

[0027] The limiting component is configured to limit one end of the spindle box. The tensioning component includes a first guide rail 41, a first slider 42 movable along the first guide rail 41, a first locking member 43 for locking the position of the first slider 42, and a second adjusting bolt 44 disposed on the first slider 42 for limiting the other end of the spindle box.

[0028] Using this device, during machining, the spindle box is placed on the clamping assembly, one side guide rail is placed on the L-shaped support surface of the second support base 22, and the other side guide rail is placed on the base 211, with one end abutting against the limiting assembly. Adjusting the first adjusting bolt 213 clamps both sides of the spindle box. Then, adjusting the first slider 42 to a suitable position and locking it, and finally adjusting the second adjusting bolt 44 to abut against the other end of the spindle box, clamps the spindle box. This structure enables rapid clamping of the spindle box, thereby improving clamping efficiency.

[0029] The first support and the second support 22 are clamped from both sides of the spindle box. In the working state, both the first support and the second support 22 are load-bearing components. For structural stability, the first support is an integral structure.

[0030] During long-term operation, the clamping plate 212 is prone to deformation due to stress. To facilitate component replacement, the base 211 and the clamping plate 212 are detachably connected by bolts.

[0031] For structural stability, a reinforcing rib 6 is provided between the first support and / or base 211 and the processing base 1. By adding the reinforcing rib, the rigidity is greatly improved.

[0032] The limiting component limits one end of the spindle box, and there are many ways to achieve this, such as directly fixing an L-shaped plate to the machining base 1. However, this structure is not convenient for quick installation of the spindle box because, during clamping, one end of the spindle box needs to be adjusted to abut against the limiting component. To further improve the clamping speed, the limiting component includes a second guide rail 51, a second slider 52 that can move along the second guide rail 51 and abuts against one end of the spindle box, and a second locking member for locking the position of the second slider 52.

[0033] To improve the stability of the spindle box clamping, the first guide rail 41 and the second guide rail 51 are placed on the same straight line.

[0034] In order to reduce the overall tooling manufacturing cost while ensuring the stability of the spindle box clamping, there are two sets of the first support seat and the second support seat 22.

[0035] The first locking element 43 controls the locking and unlocking of the first slider and the first guide rail, and there are various ways to achieve this. To facilitate operation and reduce manufacturing costs, such as... Figure 3As shown, the first guide rail 41 is provided with an inverted T-shaped guide groove. The first locking member 43 includes a locking bolt 431 disposed on the first slider 42 with one end placed in the guide groove, and a nut 432 sleeved on the locking bolt 431. The nut 432 is placed at the bottom of the inverted T-shaped guide groove, and its upper and lower end faces do not contact the groove simultaneously. With the above structure, the locking and unlocking control between the first slider and the first guide rail can be achieved by rotating the locking bolt.

[0036] The second guide rail 51, the second slider 52, and the second locking component of the limiting assembly can all be implemented using the above structure.

[0037] The first slider 42 and the second slider 52 preferably adopt an L-shaped structure.

[0038] Based on the above-described tooling structure, the second aspect of this utility model discloses a spindle box clamping structure, which includes a spindle box clamping fixture as described in the first aspect and a spindle box 5. The guide rails on both sides of the spindle box 5 are placed on the first support seat and the second support seat 22. The clamping of the spindle box is as described in the first aspect and will not be repeated here.

[0039] To avoid the need for manual alignment of the top and side surfaces of the spindle box guide rails during grinding, a standard post 53 can be further installed on the top surface of one end of the spindle box 5.

[0040] Preferably, the standard posts 53 are simultaneously set on both sides of the top surface of the spindle box 5, and the end faces of the two standard posts 53 are flush with the top surface of the guide rail.

[0041] With this structure, a standard post 53 is pre-set on the spindle box blank as a reference surface for the first clamping, replacing manual alignment. During grinding, the guide rail surface is ground with the standard post 53 as the reference, thereby improving the processing speed.

[0042] During the clamping process, during the first clamping, the four guide rail surfaces are ground using the standard column 53 as a reference, requiring only the side surfaces of the guide rails to be corrected; during the second clamping, a special fixture is used directly, with the machined guide rail surfaces as a reference, and automatic positioning is achieved through the guide backing surface, eliminating the need for manual leveling. This structure enables rapid clamping.

[0043] Using existing technology, the calibration time for a single spindle box is greater than 20 minutes, and the processing time is greater than or equal to 120 minutes; using the structure described in this solution, the calibration time for a single spindle box is less than 5 minutes, and the processing time is less than or equal to 100 minutes.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
