Abstract
Description
Technical Field
[0001] The utility model relates to the field of tooling, in particular to a fixed tooling which is convenient for a hand electric drill to drill holes on a cover plate. Background Art
[0002] Wind power generation has developed rapidly in recent years due to its advantages such as no pollution and low construction cost. The gearbox is a key part in the wind turbine generator set, and there are many cover parts on the outside of the gearbox. The processing efficiency of cover parts is crucial. The threaded holes and through holes on the cover are usually placed on the machine tool for processing. However, when encountering a cover with few processing requirements, it is directly arranged on the machine tool for processing, which not only wastes time, but also causes a waste of machine tool capacity. Therefore, in order to save time and also to save the capacity of the machine tool, the processing personnel often find the center of the threaded hole or through hole required to be processed by marking, and then directly use a hand drill for processing. Although this method is fast, it has a lot of human factors. During the processing process, if the hand drill is not held steady, it is easy to cause the drill bit to be eccentric, which will cause the threaded hole or through hole required to be processed to exceed the range. Severe deviations may even cause the cover to be scrapped, resulting in unnecessary losses.
[0003] One of the existing technologies is:
[0004] According to the outer contour dimensions of the cover parts on the wind turbine gearbox provided by the designers, equal height blocks are made in advance to support the lower plane of the cover parts. Since the T-slots on the machine tool worktable are far apart, when encountering small structural parts, they can only be fixed with a longer tooling pressure plate.
[0005] The disadvantages of the above prior art are:
[0006] 1. When encountering cover parts with very different outline dimensions, it is necessary to manufacture various equal-height blocks of different heights and pressure plates of different lengths, and the cost of tooling is relatively high.
[0007] 2. To process cover parts of different sizes, it is necessary to switch back and forth between equal height blocks and pressure plates, resulting in a long waiting time for the machine tool and the machine tool's production capacity cannot be fully utilized.
[0008] 3. Some cover plates only require processing of a few through holes or threaded holes, and the processing content is very small. If they are placed on a machine tool for processing, it will cause a waste of production capacity.
[0009] The second prior art is:
[0010] Processing personnel often find the center of the threaded hole or through hole to be processed by marking, and then directly use a hand drill to process it.
[0011] The disadvantages of the above prior art are:
[0012] 1. Affected by human factors, unstable hand-held electric drill will cause the drill bit to be eccentric, which will cause the required threaded holes or through holes to be out of range. Severe deviations may even cause the cover to be scrapped, resulting in unnecessary losses. Utility Model Content
[0013] The utility model provides a fixing tool for making holes on a cover plate with a hand electric drill, aiming to solve the disadvantages of the prior art, so that the drill bit of the hand electric drill will not deviate during the processing and the processing cost is saved.
[0014] The technical solution adopted by the utility model to solve its technical problems is:
[0015] A fixed tooling for making holes on the cover plate with a hand drill.
[0016] The workbench is fixed on the tooling base, and the workpiece cover is placed on the workbench;
[0017] The column is fixed on the tooling base, the spring is sleeved outside the column, the sleeve is slidably and rotatably sleeved outside the column, and the sleeve is mounted on the spring;
[0018] The first clamp is fixedly sleeved on the sleeve, and the second clamp is fixedly sleeved on the hand electric drill with the drill bit facing downward, and the first clamp and the second clamp are fixedly connected;
[0019] The hand drill is located above the workpiece cover.
[0020] The two ends of the connecting plate are respectively welded and fixedly connected to the first clamp and the second clamp, so that the connecting plate connects the first clamp and the second clamp together.
[0021] There are two connecting plates in total.
[0022] The workbench is welded on the tooling base, which is an integral platform formed by welding two side plates and an upper plate.
[0023] The column is placed on the tooling base, and the bolts are passed through the through holes provided in the tooling base and then screwed into the threaded holes provided on the bottom surface of the column to fix the column to the tooling base.
[0024] The bolts are passed through the through holes at both ends of the first clamp and then screwed with nuts to fix the first clamp and the sleeve; the bolts are passed through the through holes at both ends of the second clamp and then screwed with nuts to fix the second clamp and the hand drill.
[0025] The utility model is beneficial in that:
[0026] 1) For cover plates with less processing content, they can be directly placed on the workbench of the tooling of the utility model for processing. The utility model has simple structural parts and low manufacturing cost, which effectively saves the cost of machine tools;
[0027] 2) The hand drill in the utility model can be moved up and down at will, and can also be rotated relative to the column. According to the position of the line drawn on the cover plate in advance, the drill bit of the hand drill can be adjusted to the line position and then the processing can be carried out directly. In addition, the hand drill is fixed by a clamp, which can effectively reduce the unqualified processing of the cover plate caused by the drill bit not being perpendicular to the workpiece plane due to human factors. BRIEF DESCRIPTION OF THE DRAWINGS
[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0031] In order to more clearly illustrate the technical solution of the utility model, the following will briefly introduce the drawings required for the description. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other embodiments can be obtained based on these drawings without creative work. In order to facilitate the understanding of the utility model, the following will be combined with the drawings and specific embodiments to explain the utility model in more detail.
[0032] It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more centered elements can exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more centered elements can exist between them. The terms "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0033] like Figure 1 , Figure 2 As shown:
[0034] The tooling base 1 is an integral platform formed by welding two side plates and an upper plate. The workbench 2 is fixed to the tooling base 1 by welding, and the workpiece cover plate 3 is directly placed on the workbench 2 for processing.
[0035] A through hole is opened in the middle of the left side of the plane on the tooling base 1. The column 4 is a solid column. A threaded hole is processed in advance at the center of the circle below the column 4. After the bolt 5 passes through the through hole processed in advance on the plane of the tooling base 1, it is screwed into the threaded hole processed in advance on the column 4 to fix the column 4 to the tooling base 1. Then the spring 6 is sleeved outside the column 4 to ensure that the inner diameter of the spring 6 is slightly larger than the outer diameter of the column 4. Then the sleeve 7 is sleeved outside the column 4. Since the sleeve 7 is a hollow cylinder, the sleeve 7 and the column 4 are clearance-matched, the sleeve 7 can slide and rotate on the column 4, and the outer diameter of the tooling sleeve 7 is smaller than the outer diameter of the spring 6. In this way, the sleeve 7 can be in contact with the upper end surface of the spring 6, that is, the sleeve 7 is mounted on the spring 6.
[0036] The first clamp 8 is sleeved on the sleeve 7, and the bolts 9 are passed through the through holes at both ends of the first clamp 8 and then screwed with nuts 18. By tightening the combination of the bolts 9 and nuts 18 on the first clamp 8, the first clamp 8 is fixed to the sleeve 7. The two ends of the connecting plate 10 are respectively welded and fixed to the first clamp 8 and the second clamp 12, so that the connecting plate 10 connects the first clamp 8 and the second clamp 12 together. There are two connecting plates 10, one at the front and one at the back.
[0037] After the drill bit of the hand drill 13 is passed downward through the second clamp 12, the second clamp 12 is sleeved on the hand drill 3, and the bolt 11 is passed through the through holes at both ends of the second clamp 12 and then screwed with nuts 19. The second clamp 12 is fixed to the hand drill 13 by tightening the combination of the bolt 11 and the nut 19 on the second clamp 12. After the hand drill 13 is firmly fixed, the position of the hand drill 13 is controlled according to the position of the line drawn in advance on the workpiece cover plate 3 to be processed, so that the hand drill 13 is above the workpiece cover plate 3. By pressing the hand drill 13 downward, the first clamp 8 is driven to move downward. Since the first clamp 8 and the sleeve 7 are fixed, the sleeve 7 is driven to transmit the force to the spring 6, so that the angle of the drill bit of the hand drill 13 is always perpendicular to the plane of the workpiece cover plate 3 during the processing.
[0038] The utility model has the following advantages:
[0039] 1: By using the fixed tooling in the utility model, when using a hand drill to process cover plate parts, compared with the manual hand-held method, the utility model can ensure that the drill bit of the hand drill will not deviate during the processing process, the clamping is more stable, and the processed holes can better meet the technical requirements;
[0040] 2: The workbench of the utility model can meet the processing of cover plate parts within a certain range, effectively saving the cost of tooling. For workpieces with relatively simple processing content, they only need to be placed on the tooling to meet the processing requirements, and there is no need to place them on the machine tool for processing, which effectively improves the utilization rate of the machine tool.
[0041] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the embodiments can be referred to each other. The above description of the disclosed embodiments enables professionals and technicians in this field to implement or use the utility model. Various modifications to these embodiments will be obvious to professionals and technicians in this field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to the embodiments shown herein, but will conform to the widest range consistent with the principles and novel features disclosed herein.
