Description

Technical Field

[0001] The utility model relates to the technical field of spindle box processing equipment, in particular to a spindle box processing tool. Background Art

[0002] The spindle box is an important part of the machine tool. It is used to arrange the working spindle of the machine tool and its transmission parts and corresponding additional mechanisms. The spindle box is a complex transmission component, including the spindle assembly, reversing mechanism, transmission mechanism, braking device, operating mechanism and lubrication device. Its main function is to support the spindle and make it rotate, and realize the functions of spindle starting, braking, speed change and reversing.

[0003] The spindle box needs to have corresponding fixing holes according to the installation position requirements of the spindle assembly, reversing mechanism, transmission mechanism, etc., and the traditional processing method is to bore each hole one by one. In this way, during the boring process, the staff needs to constantly turn the spindle box, which increases the workload of the staff and is not conducive to improving production efficiency. Moreover, since it is manually turned and fixed, the accuracy will be relatively low, so the quality of the processed spindle box is generally not very ideal. Therefore, it is necessary to use a tooling to fix the spindle box so as to better process it.

[0004] In response to this problem, Chinese patent CN 108568674 A discloses a processing tool for a spindle box, comprising a tool body (1), the back of the tool body (1) being an insertion port (15), and characterized in that: the bottom of the tool body (1) is provided with four support blocks (14), the support blocks (14) being distributed in a rectangular shape and corresponding to the four vertex corners of the bottom of the spindle box; the front of the tool body (1) is provided with a contact piece (2) capable of supporting the front of the spindle box; the two side surfaces of the tool body (1) are respectively provided with a processing hole (11) corresponding to auxiliary hole 1 (8c), auxiliary hole 2 (8d) and auxiliary hole 3 (8e) and for a boring tool to pass through, and two symmetrical arc openings (13), and the arc openings (15) are located on both sides of the insertion port (15); and the top of the tool body (1) is provided with a cylinder (3) for pressing the top of the spindle box. Although this spindle box processing tooling can fix the spindle box well, it has a complex structure and high manufacturing cost, and cannot completely expose the circumference of the spindle box, which increases the difficulty of processing the spindle box fixing hole.

[0034] Please refer to Figure 1 , which is a spindle box processing tooling 100 according to an embodiment of the present utility model, including a bottom plate 10, a rear fixing mechanism 20, a front fixing rod 30 and a fixing pressing plate 50. The rear fixing mechanism 20 is fixedly arranged on the bottom plate 10. The front fixing rod 30 is arranged opposite to the rear fixing mechanism 20 in the front and rear directions. The front fixing rod 30 is slidably arranged on the bottom plate 10. The number of the fixing pressing plates 50 is two. One fixing pressing plate 50 is arranged on the rear fixing mechanism 20, and the other fixing pressing plate 50 is arranged on the front fixing rod 30.

[0035] Please refer to Figure 1 , three sliding grooves 11 are arranged on the bottom plate 10. The three sliding grooves 11 are arranged in parallel at intervals. A slider 12 is slidably arranged in each sliding groove 11. The slider 12 is provided with a fixing screw hole penetrating along its vertical direction.

[0036] Please refer to Figure 1 , the rear fixing mechanism 20 includes a rear fixing column 21, a limiting sleeve 22, an adjusting bolt and a rear fixing rod 23. Adjusting grooves 211 are arranged at intervals along the circumferential direction of the rear fixing column 21. Adjusting screw holes 221 are arranged at intervals in the circumferential direction of the limiting sleeve 22. The adjusting bolt passes through the adjusting screw hole 221 and extends into the adjusting groove 211. The limiting sleeve 22 is sleeved outside the rear fixing column 21 in a height-adjustable manner. The cross-section of the limiting sleeve 22 gradually expands outwards from top to bottom. The maximum diameter of the limiting sleeve 22 is larger than the diameter of the shaft hole 201 of the spindle box 200. The limiting sleeve 22 can adjust its position on the rear fixing rod 23 according to the height of the spindle box 200, effectively expanding the applicable range of the spindle box processing tooling 100. The rear fixing rod 23 includes a main rear rod portion 231 and a rear screw portion 232 connecting the main rear rod portion 231. A plugging hole is arranged on the rear fixing column 21. The main rear rod portion 231 is inserted into the plugging hole. The fixing pressing plate 50 is screwed to the rear screw portion 232.

[0037] Please refer to Figure 1, the front fixing rod 30 includes a front main rod portion 31, a lower screw rod portion 32 connecting the front main rod portion 31, and an upper screw rod portion 33 connecting the front main rod portion 31. A fixing screw hole is provided through the slider 12 in its vertical direction. The lower screw rod portion 32 is threadedly connected to the fixing screw hole, and the fixing pressing plate 50 is screwed to the upper screw rod portion 33. In this way, the position of the front fixing rod 30 can be adjusted according to the length of the main spindle box 200, effectively expanding the applicable range of the main spindle box processing tooling 100.

[0038] Please refer to Figure 1 , the main spindle box processing tooling 100 further includes a ejector rod 40. The number of the ejector rods 40 is two.

Then, one fixing pressing plate 50 is screwed to the front fixing rod 30, and the other fixing pressing plate 50 is screwed to the rear fixing rod 23. Thus, the fixing pressing plate 50 can press the main spindle box 200 tightly, preventing the main spindle box 200 from shifting during the processing. Such a fixing method can expose multiple circumferential surfaces of the main spindle box 200, making it more convenient for the user to process the main spindle box 200, and it is more convenient and practical to use.

[0040] The beneficial effects of the present utility model are as follows: The main spindle box 200 can be fixed through the cooperation of the bottom plate 10, the rear fixing mechanism 20, the front fixing rod 30, and the fixing pressing plate 50, effectively preventing the main spindle box 200 from shifting during the processing, effectively improving the processing quality. Moreover, during the process of fixing the main spindle box 200, multiple circumferential surfaces of the main spindle box 200 can be exposed, making it more convenient for the user to process the main spindle box 200, and it is more convenient and practical to use; the structure of the main spindle box processing tooling 100 is simple and the manufacturing cost is low.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.
