Description

Technical Field

[0002] A high-voltage switch is a device used to open and close conductive circuits. The structure of the high-voltage switch base is shown in Chinese patent application number 201320485972.5, which discloses an integrated high-voltage switch base, including a base, a bearing seat, mounting feet and mounting holes; the bearing seat is integrally formed with the base; and reinforcing ribs I and II are fixed on the bearing seat.

[0003] When using the high-voltage switch base provided by the aforementioned patent, the bearing needs to be fixed inside the bearing housing. Therefore, the accuracy of the opening of the bearing housing affects whether the bearing can be tightly fixed. Furthermore, in this high-voltage switch base, the bearing housing and the base are integrally formed. Thus, when processing the opening of the bearing housing, if the high-voltage switch base is not securely fixed and the processing equipment deviates from the required processing position of the high-voltage switch base, the accuracy of the opening of the bearing housing will be deviated, thereby affecting the subsequent assembly and use of the high-voltage switch base.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a tooling for processing high-voltage switch bases, including a base plate, a boss, a sliding limit assembly, and a clamping assembly;

[0007] If the substrate is horizontally arranged, the boss is located on the upper surface of the substrate; the top plane of the boss is inclined; the top plane of the boss is inclined in the front-back direction.

[0008] The sliding limiting assembly includes four limiting pins; the four limiting pins are distributed on the top plane of the boss; the limiting pins are cylindrical, and the axis of the limiting pins is perpendicular to the top plane of the boss; the four limiting pins are arranged in pairs, one in front of the other; the four limiting pins are arranged in pairs, one in front of the other.

[0009] The clamping assembly includes two clamping parts; each clamping part includes a pressure plate; the surface of the pressure plate is parallel to the top plane of the boss; the pressure plate is located above the boss; the pressure plates of the two clamping parts are arranged left and right; the pressure plate moves in the vertical direction.

[0010] The tooling for processing high-voltage switch bases provided by this utility model preferably includes a stud, a spring, and a bolt in the clamping part; the stud is fixed to the top plane of the boss; the axis of the stud is perpendicular to the top plane of the boss; the spring is sleeved on the stud; a through hole is provided on the pressure plate for the bolt to pass through; the pressure plate is located above the stud and the spring; the guide part of the bolt passes through the through hole and is fixed in the screw hole of the stud.

[0011] The tooling for processing high-voltage switch bases provided by this utility model preferably has a through hole that is a waist hole; the through hole extends in the left-right direction.

[0012] The tooling for processing high-voltage switch bases provided by this utility model preferably includes a limiting post in the clamping part; the limiting post is cylindrical; the limiting post is fixed to the top plane of the boss; the axis of the limiting post is perpendicular to the top plane of the boss.

[0013] The pressure plate is also provided with a limiting hole; the limiting hole is a waist hole; the limiting hole extends in the left and right direction; the end of the pressure plate near the center of the boss is taken as the inner side of the pressure plate, and the limiting hole is located outside the through hole; the limiting post is sleeved in the limiting hole.

[0014] The tooling for processing high-voltage switch bases provided by this utility model preferably includes a baffle at the bottom of the pressure plate; the surface of the baffle is perpendicular to the surface of the pressure plate; and the baffle extends in the front-to-back direction.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] The tooling provided by this utility model for processing high voltage switch bases requires that the high voltage switch base be assembled on the tooling fixture in order to stably fix the high voltage switch base on the worktable of a vertical boring machine, and then the tooling fixture be fixed to the worktable. Specifically, the tooling includes a base plate, a boss, a sliding limit assembly and a clamping assembly.

[0017] The substrate is set horizontally to fit the plane of the worktable, facilitating the fixing of the substrate to the worktable. Since the axis of the bearing seat on the high-voltage switch base is inclined to the bottom plane of its base, vertical machining can be performed using a boring tool, but it is impossible to machine the inclined opening on the bearing seat. Therefore, a boss needs to be added, with the boss located on the upper surface of the substrate, making the top plane of the boss inclined. This causes the high-voltage switch base placed on the boss to be inclined, and the axis of the opening of the bearing seat on the high-voltage switch base is perpendicular to the plane of the worktable of the vertical boring machine, thereby realizing the machining of the inclined bearing seat opening. Here, for the sake of explaining the tooling structure, the top plane of the boss is inclined in the front-back direction.

[0018] To secure the high-voltage switch base to the base plate, the sliding limiting assembly includes four limiting pins distributed on the top plane of the boss, used to restrict the high-voltage switch base from sliding on the top plane of the boss. The limiting pins are cylindrical, allowing them to engage with the four mounting holes of the high-voltage switch base, preventing the high-voltage switch from wobbling during machining due to gaps between the limiting pins and the mounting holes. To adapt the high-voltage switch base to the inclined top plane of the boss, the axis of the limiting pins is perpendicular to the top plane of the boss, allowing the mounting holes on the high-voltage switch base to fit onto the limiting pins. To enable the boring bar to vertically bore the opening of the bearing seat on the high-voltage switch base, the four limiting pins are arranged in pairs, front and back, and left and right, so that the axis of the bearing seat on the high-voltage switch base is perpendicular to the worktable plane of the vertical boring machine through the inclined surface of the boss, preventing the ends of the high-voltage switch base with the bearing seat from tilting to the left or right, which would cause the axis of the bearing seat to tilt relative to the worktable plane of the vertical boring machine.

[0019] Furthermore, to prevent the high-voltage switch base from wobbling up and down during processing and affecting the machining accuracy of the bearing seat opening, the clamping assembly specifically includes two clamping parts for simultaneously pressing down on both sides of the high-voltage switch base. More specifically, the clamping part includes a pressure plate located above the boss. The pressure plates of the two clamping parts are arranged left and right, and the surface of the pressure plate is parallel to the top plane of the boss, thereby achieving full contact between the pressure plate and the high-voltage switch base in an inclined state and improving the clamping stability of the pressure plate on the high-voltage switch base. Here, the pressure plate moves in the vertical direction, which can realize the pressure plate pressing down to press the high-voltage switch base against the boss, or releasing the pressure plate to put in and take out the high-voltage switch base.

[0020] In existing technologies, if the high-voltage switch base is not securely fixed during the machining of the bearing housing opening, the machining equipment may shift to the required machining position of the high-voltage switch base, leading to deviations in the accuracy of the bearing housing opening and affecting the subsequent assembly and use of the high-voltage switch base. To address this, the present invention provides a tooling for machining high-voltage switch bases. By setting a boss, the axis of the bearing housing opening on the high-voltage switch base is made perpendicular to the worktable plane of the vertical boring machine, enabling the machining of inclined bearing housing openings. Four limiting pins are set on the top plane of the boss to restrict the high-voltage switch base from sliding on the top plane of the boss. Pressure plates located on the left and right sides are used to press the high-voltage switch base firmly against the boss. This structure stably fixes the high-voltage switch base to the worktable of the vertical boring machine and facilitates the boring tool of the vertical boring machine to bore the bearing housing opening on the high-voltage switch base.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0025] Example 1:

[0026] like Figures 1-2 As shown, Embodiment 1 of this utility model provides a tooling for processing a high-voltage switch base, including a base plate 1, a boss 2, a sliding limit assembly 3, and a clamping assembly 4;

[0027] If the substrate 1 is horizontally arranged, the boss 2 is located on the upper surface of the substrate 1; the top plane of the boss 2 is inclined; the top plane of the boss 2 is inclined in the front-back direction.

[0028] The sliding limit assembly 3 includes four limit pins 31; the four limit pins 31 are distributed on the top plane of the boss 2; the limit pins 31 are cylindrical, and the axis of the limit pins 31 is perpendicular to the top plane of the boss 2; the four limit pins 31 are arranged in pairs, one in front of the other; the four limit pins 31 are arranged in pairs, one in front of the other;

[0029] The clamping assembly 4 includes two clamping parts 41; each clamping part 41 includes a pressure plate 411; the surface of the pressure plate 411 is parallel to the top plane of the boss 2; the pressure plate 411 is located above the boss 2; the pressure plates 411 of the two clamping parts 41 are arranged left and right; the pressure plates 411 move in the vertical direction.

[0030] When using the tooling for machining the high-voltage switch base provided in Embodiment 1 of this utility model, the base plate 1 is fixed to the worktable of a vertical boring machine. The boring machine structure used here is as disclosed in Chinese Patent Application No. 201720362533.3. The high-voltage switch base is placed on the top plane of the boss 2. The bearing seat on one side of the high-voltage switch base is selected for machining and is designated as the first bearing seat, and the bearing seat on the other side is designated as the second bearing seat. The first bearing seat is positioned on the higher side of the inclined surface of the boss 2, and the four mounting holes of the high-voltage switch base are respectively fitted onto the outside of the four limiting pins 31. At this time, the axis of the bearing seat is perpendicular to the worktable plane of the vertical boring machine, and the bearing... The base is located directly below the boring bar; the pressure plates 411 of the two clamping parts 41 are pressed down vertically, and the pressure plates 411 of the left and right clamping parts 41 press down on the left and right sides of the high voltage switch base respectively. The pressure plates 411 contact the upper surface of the base of the high voltage switch base, and the pressure plates 411 press the high voltage switch base onto the boss 2; the spindle of the vertical boring machine is rotated, which drives the boring bar mounted on the spindle to rotate, and the opening side wall of the first bearing seat is bored; after the opening of the first bearing seat is completed, the pressure plates 411 are removed, the high voltage switch base is rotated 180°, so that the second bearing seat is on the side of the higher slope of the boss 2, and the above limiting operation is repeated to bore the opening of the second bearing seat.

[0031] This utility model provides a tooling for processing a high-voltage switch base according to Embodiment 1. In order to stably fix the high-voltage switch base on the worktable of a vertical boring machine, the high-voltage switch base needs to be assembled on the tooling fixture, and then the tooling fixture is fixed to the worktable. Specifically, the tooling includes a base plate 1, a boss 2, a sliding limit component 3, and a clamping component 4.

[0032] The substrate 1 is set horizontally to fit the plane of the worktable, which facilitates the fixing of the substrate 1 to the worktable. Since the axis of the bearing seat on the high-voltage switch base is inclined to the bottom plane of its base, it is impossible to process the inclined opening on the bearing seat by using a boring tool, as vertical machining is possible. Therefore, a boss 2 needs to be added, with the boss 2 located on the upper surface of the substrate 1, so that the top plane of the boss 2 is inclined. This causes the high-voltage switch base placed on the boss 2 to be inclined, and the axis of the opening of the bearing seat on the high-voltage switch base is perpendicular to the plane of the worktable of the vertical boring machine, thereby realizing the machining of the inclined bearing seat opening. Here, for the sake of explaining the tooling structure, the top plane of the boss 2 is inclined in the front-back direction.

[0033] To fix the high-voltage switch base to the base plate 1, specifically, the sliding limiting assembly 3 includes four limiting pins 31, which are distributed on the top plane of the boss 2 to restrict the sliding of the high-voltage switch base on the top plane of the boss 2. The limiting pins 31 are cylindrical so that they can mate with the four mounting holes of the high-voltage switch base, preventing the high-voltage switch from wobbling during processing due to gaps between the limiting pins 31 and the mounting holes. To allow the high-voltage switch base to adapt to the top plane of the inclined boss 2, the limiting pins 31 are... The axis is perpendicular to the top plane of the boss 2, so that the mounting hole on the high voltage switch base can be fitted onto the limit pin 31; in order to enable the boring tool to bore the opening of the bearing seat on the high voltage switch base perpendicularly, the four limit pins 31 are arranged in pairs front and back, and in pairs left and right, so that the axis of the bearing seat on the high voltage switch base is perpendicular to the worktable plane of the vertical boring machine through the inclined surface of the boss 2, so as to avoid the two ends of the high voltage switch base with the bearing seat tilting to the left or right, which would cause the axis of the bearing seat to tilt with the worktable plane of the vertical boring machine.

[0034] Furthermore, to prevent the high-voltage switch base from wobbling up and down during processing and affecting the machining accuracy of the bearing seat opening, the clamping assembly 4 specifically includes two clamping parts 41 for simultaneously pressing down on both sides of the high-voltage switch base. More specifically, the clamping part 41 includes a pressure plate 411, which is located above the boss 2. The pressure plates 411 of the two clamping parts 41 are arranged left and right, and the surface of the pressure plate 411 is parallel to the top plane of the boss 2, thereby achieving full contact between the pressure plate 411 and the high-voltage switch base in the inclined state, improving the clamping stability of the pressure plate 411 on the high-voltage switch base. Here, the pressure plate 411 moves in the vertical direction, which can realize that the pressure plate 411 presses down to press the high-voltage switch base against the boss 2, or releases the pressure plate 411 to put in or take out the high-voltage switch base.

[0035] In existing technologies, if the high-voltage switch base is not securely fixed during the machining of the bearing housing opening, the machining equipment may deviate from the required machining position of the high-voltage switch base, resulting in a deviation in the accuracy of the bearing housing opening and affecting the subsequent assembly and use of the high-voltage switch base. Therefore, the tooling for machining the high-voltage switch base provided in Embodiment 1 of this utility model, by setting a boss 2, ensures that the axis of the bearing housing opening on the high-voltage switch base is perpendicular to the worktable plane of the vertical boring machine, thus enabling the machining of the inclined bearing housing opening. Four limiting pins 31 are set on the top plane of the boss 2 to restrict the high-voltage switch base from sliding on the top plane of the boss 2. Pressure plates 411 located on the left and right sides are used to press the high-voltage switch base firmly against the boss 2. Through the above structure, the high-voltage switch base can be stably fixed to the worktable of the vertical boring machine, facilitating the boring tool of the vertical boring machine to perform boring machining on the bearing housing opening of the high-voltage switch base.

[0036] The tooling for processing high-voltage switch bases provided in Embodiment 1 of this utility model preferably includes a stud 412, a spring 413, and a bolt 414 in order to enable the pressure plate 411 to move vertically. In order to make the plate surface of the pressure plate 411 parallel to the top plane of the boss 2, the stud 412 is fixed to the top plane of the boss 2, and the axis of the stud 412 is perpendicular to the top plane of the boss 2. Further, the spring 413 is sleeved on the stud 412, and the pressure plate 411 is located above the stud 412 and the spring 413. The spring 413 is used to lift the pressure plate 411. In order to control the height of the pressure plate 411 and to press the high-voltage switch base onto the boss 2, the pressure plate 411 has a through hole 4111 for the bolt 414 to pass through. The guide part of the bolt 414 passes through the through hole 4111 and is fixed in the screw hole of the stud 412.

[0037] When using the clamping part 41 to clamp the high-voltage switch base, first loosen the bolt 414 naturally, so that the pressure plate 411 is lifted by the spring 413, leaving space for the high-voltage switch base; then tighten the bolt 414 continuously, so that the pressure plate 411 moves downward until the pressure plate 411 clamps the top plane of the base on the high-voltage switch base.

[0038] The tooling for processing high-voltage switch base provided in Embodiment 1 of this utility model is preferably designed so that the through hole 4111 is a waist hole, which extends in the left and right direction, so that the pressure plate 411 can move in the left and right direction, thereby expanding the placement space of the high-voltage switch base and improving the placement convenience of the high-voltage switch base.

[0039] The tooling for processing high-voltage switch base provided in Embodiment 1 of this utility model preferably includes a pressure plate 411 fixed by bolts 414 and studs 412. The pressure plate 411 may shift due to rotation during processing, reducing the contact area between the pressure plate 411 and the high-voltage switch base, making the high-voltage switch base unstable. To solve this problem, the clamping part 41 also includes a limiting post 415. The limiting post 415 is cylindrical. In order to match the sliding of the pressure plate 411, the limiting post 415 is fixed to the top plane of the boss 2, and the axis of the limiting post 415 is perpendicular to the top plane of the boss 2.

[0040] In order to limit and guide the pressure plate 411, a limiting hole 4112 is also provided on the pressure plate 411. The limiting hole 4112 is a waist hole that extends in the left and right direction, so that the pressure plate 411 can move in the left and right direction while being limited. Specifically, the end of the pressure plate 411 near the center of the boss 2 is regarded as the inner side of the pressure plate 411, the limiting hole 4112 is located outside the through hole 4111, and the limiting post 415 is sleeved in the limiting hole 4112. At this time, the bolt 414 and the limiting post 415 play a role in rotating and limiting the pressure plate 411.

[0041] The tooling for processing the high-voltage switch base provided in Embodiment 1 of this utility model is preferably provided in the following way: since the tooling only uses four limiting pins 31 to slide and limit the high-voltage switch base on the boss 2, and a large extrusion force is applied when the boring tool bores the opening of the bearing seat on the high-voltage switch base, it may cause the mounting feet on the high-voltage switch base to be damaged by force. In order to solve this problem, the bottom of the pressure plate 411 is also provided with a baffle 4113, the surface of the baffle 4113 is perpendicular to the surface of the pressure plate 411, and the baffle 4113 extends in the front-back direction.

[0042] When in use, the baffle 4113 is attached to the side wall of the base on the high-voltage switch base, thereby providing a certain support force to resist the squeezing force exerted by the boring tool on the high-voltage switch base, thus preventing the mounting feet on the high-voltage switch base from being damaged by force.

[0043] In summary, the tooling provided by this utility model for processing high-voltage switch bases can solve the problem in the prior art where, if the high-voltage switch base is not securely fixed during the drilling of bearing seats, the processing equipment may deviate from the required processing position of the high-voltage switch base, leading to deviations in the accuracy of the drilling of the bearing seat and affecting the subsequent assembly and use of the high-voltage switch base; thus improving the stability of the high-voltage switch base during the processing.
