Description

Technical Field

[0001] The utility model belongs to the technical field of high-frequency power supply shell production, and in particular relates to a tool for drilling holes in a high-frequency power supply shell. Background Art

[0002] High-frequency power supply, also known as electron tube frequency conversion device, is the key equipment of high-frequency induction furnace. High-frequency power supply and induction heating technology are the most efficient and fastest devices for heating metal materials, and they are low-energy and environmentally friendly. In order to route the wires, it is necessary to drill holes in the casing (on it). When drilling holes, the power casing needs to be clamped by a tooling fixture to prevent the casing from shifting during operation. When drilling holes in the high-frequency power casing, in order to ensure the accuracy of the position, the casing needs to be clamped and tightened. However, after clamping and tightening, the casing is prone to deformation, resulting in unqualified dimensions, etc., and one tooling can only be applied to one power casing, and its applicability is poor when facing multiple power casings. At the same time, when drilling holes in the high-frequency power casing, the drill bit needs to apply pressure to produce a cutting effect. Due to the pressure applied by the drill bit on the power casing, the drilling position of the casing is prone to deformation, affecting subsequent installation. Utility Model Content

[0003] In view of the above problems, the purpose of the present utility model is to provide a tool for drilling holes in a high-frequency power supply housing to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the utility model adopts the following technical solution: a tool for drilling holes in a high-frequency power supply casing, comprising a support seat and a clamping assembly arranged on the top of the support seat and used to fix the power supply casing, the clamping assembly comprising a fixed plate arranged at one end of the top of the support seat, a first clamping plate connected to the fixed plate by a first connecting rod, a mounting groove opened in the support seat, a first transmission screw rod arranged in the mounting groove and rotatably connected to the support seat, a first motor arranged in the support seat and connected to one end of the first transmission screw rod, a movable block screwed to the outer wall of the first transmission screw rod, a strip groove opened in the middle of the support seat and used for sliding of the movable block, a movable plate arranged at the top of the movable block, a second clamping plate connected to the movable plate by a second connecting rod, and a positioning assembly arranged between the first clamping plate and the second clamping plate and used to support the inner wall of the power supply casing when drilling.

[0005] The beneficial effects of the utility model are as follows: the utility model can not only clamp and fix the power supply casing during the process of drilling the hole in the power supply casing to ensure the stability of the drilling of the power supply casing, but also support the inner top wall and the inner bottom wall of the power supply casing during the drilling process to prevent the drill bit from applying external force to the power supply casing during the drilling process to cause deformation.

[0006] To prevent the power supply housing from deforming during drilling:

[0007] As a further improvement of the above technical solution: the positioning assembly includes a supporting shell which is arranged on the side of the first clamping plate away from the fixed plate and has a slot therein, a supporting rod which is arranged on the side of the second clamping plate away from the movable plate and is adapted to the size of the slot, an electric telescopic rod symmetrically arranged on the top and bottom of the supporting shell and the supporting rod, and a support plate arranged at the tail end of the electric telescopic rod.

[0008] The beneficial effects of this improvement are as follows: first, the power supply casing is inserted into the supporting casing so that one end of it contacts the first clamping plate, and then the first transmission screw is driven to rotate by the first motor, driving the movable block, the movable plate and the second clamping plate to slide toward the side close to the power supply casing, so that the support rod is inserted into the interior of the power supply casing along the other side of the power supply casing, and the power supply casing is fixed with the cooperation of the second clamping plate, and the support plate is driven to move to contact the inner bottom wall and the inner top wall of the power supply casing by controlling the electric telescopic rod to support it, so as to prevent the power supply casing from deforming during the drilling process.

[0011] The beneficial effect of this improvement is that when the electric telescopic rod drives the support plate to support the power supply casing, the buffer plate first contacts the power supply casing, and under the elastic action of the spring, the buffer plate buffers the force applied to the power supply casing by the support plate, and can also buffer the force applied to the power supply casing by the drill bit, thereby further preventing the power supply casing from being deformed.

[0012] In order to make the power supply housing fall on the support base to ensure the stability of the power supply housing:

[0013] As a further improvement of the above technical solution: the fixed plate is connected to the supporting shell via a first adjusting component, and the movable plate is connected to the supporting rod via a second adjusting component.

When drilling, the power supply shell falls on the support seat, thereby ensuring the stability of the power supply shell.

[0015] To adjust the height of the support housing and support rods to fit the dimensions of the power supply housing:

[0016] As a further improvement of the above technical solution: the first adjustment component and the second adjustment component both include a support frame arranged on the side wall of the fixed plate or the movable plate, a second transmission screw rotatably connected to the inside of the support frame, a second motor arranged at the bottom end of the second transmission screw, a slider screwed on the outer wall of the second transmission screw and connected to the support shell or support rod through a connecting column, and a strip groove opened in the middle of the first splint or the second splint and used for the movement of the connecting column.

[0017] The beneficial effect of this improvement is that when adjusting the height of the support shell and the support rod, the second transmission screw is driven to rotate by the second motor, driving the slider, the connecting column and the support shell or the support rod to move so that they are adapted to the size of the power supply shell.

[0018] In order to enable the second clamping plate to clamp the power supply housing with the cooperation of the first clamping plate:

[0019] As a further improvement of the above technical solution: the second motor located at one side of the movable plate is arranged on the top of the movable block and moves with the movable block.

[0020] The beneficial effect of this improvement is that when the movable block slides along the first transmission screw rod, it drives the second motor and the support frame to move, so that the power supply housing can be clamped and fixed under the cooperation of the first clamping plate and the second clamping plate.

[0021] In order to facilitate the export of debris from the power supply housing that falls into the installation slot:

[0022] As a further improvement of the above technical solution: the side wall of the support seat is provided with a guide groove connected to the installation groove, and the inner bottom wall of the installation groove and located below the first transmission screw rod is provided with an inclined chip guide plate.

[0023] The beneficial effect of this improvement is that when drilling a hole in the power supply housing, the debris on the power supply housing falls into the installation groove along the strip groove and is then guided out along the chip guide plate and the guide groove.

[0032] like Figure 1-6As shown, a tool for drilling holes in a high-frequency power supply housing comprises a support seat 1 and a clamping assembly arranged on the top of the support seat 1 and used to fix the power supply housing 2, wherein the clamping assembly comprises a fixing plate 3 arranged at one end of the top of the support seat 1, a first clamping plate 4 connected to the fixing plate 3 through a first connecting rod, a mounting groove 5 provided inside the support seat 1, a first transmission screw 6 provided inside the mounting groove 5 and rotatably connected to the support seat 1, a first motor 7 provided inside the support seat 1 and connected to one end of the first transmission screw 6, a movable block 8 screwed to the outer wall of the first transmission screw 6, a strip groove 9 provided in the middle of the support seat 1 and used for sliding of the movable block 8, a movable plate 10 provided at the top of the movable block 8, and a first connecting rod 8 connected to the movable plate 10 through a second connecting rod. The second clamping plate 11 connected to each other and the positioning component arranged between the first clamping plate 4 and the second clamping plate 11 and used to support the inner wall of the power supply housing 2 when drilling. The utility model can not only clamp and fix the power supply housing 2 during the drilling process of the power supply housing 2 to ensure the stability of the drilling of the power supply housing 2, but also support the inner top wall and the inner bottom wall of the power supply housing 2 during the drilling process to prevent the power supply housing 2 from being deformed by the drill bit applying external force to the power supply housing 2 during the drilling process. The positioning component includes a supporting shell 13 arranged on the side of the first clamping plate 4 away from the fixed plate 3 and having a slot 12 therein, a support rod 14 arranged on the side of the second clamping plate 11 away from the movable plate 10 and adapted to the size of the slot 12, and a support rod 14 symmetrically arranged on the side of the second clamping plate 11 away from the movable plate 10 and adapted to the size of the slot 12. The electric telescopic rod 15 at the top and bottom of the support shell 13 and the support rod 14, and the support plate 16 arranged at the tail end of the electric telescopic rod 15, first insert the power supply shell 2 into the support shell 13, so that one end of it contacts with the first clamping plate 4, and then drive the first transmission screw 6 to rotate through the first motor 7, drive the movable block 8, the movable plate 10 and the second clamping plate 11 to slide toward the side close to the power supply shell 2, so that the support rod 14 is inserted into the inside of the power supply shell 2 along the other side of the power supply shell 2, and the power supply shell 2 is fixed with the cooperation of the second clamping plate 11, and the support plate 16 is driven by controlling the electric telescopic rod 15 to move to contact with the inner bottom wall and the inner top wall of the power supply shell 2 to support it, so as to prevent the power supply shell 2 from deforming during the drilling process. The four corners of the plate 16 are slidably connected with a slide bar 17, and the end of the slide bar 17 away from the electric telescopic rod 15 is connected with a buffer plate 18. The outer wall of the slide bar 17 and the buffer plate 18 and the support plate 16 are connected with a buffer spring 19. When the electric telescopic rod 15 drives the support plate 16 to support the power supply housing 2, the buffer plate 18 first contacts with the power supply housing 2. Under the elastic action of the spring, the buffer plate 18 buffers the force applied to the power supply housing 2 by the support plate 16, and can also buffer the force applied to the power supply housing 2 by the drill bit, so as to further prevent the power supply housing 2 from being deformed. The fixed plate 3 is connected to the support housing 13 by a first adjusting component, and the movable plate 10 is connected to the support rod 14 by a second adjusting component.By setting the first adjustment component and the second adjustment component, the height of the support shell 13 and the support rod 14 can be easily adjusted to adapt to power supply shells 2 of different sizes. When drilling, the power supply shell 2 falls on the support seat 1, thereby ensuring the stability of the power supply shell 2. The first adjustment component and the second adjustment component both include a support frame 20 arranged on the side wall of the fixed plate 3 or the movable plate 10, a second transmission screw 21 rotatably connected to the inside of the support frame 20, a second motor 22 arranged at the bottom end of the second transmission screw 21, a slider 24 that is screwed on the outer wall of the second transmission screw 21 and connected to the support shell 13 or the support rod 14 through a connecting column 23, and a strip groove 9 opened in the middle of the first clamping plate 4 or the second clamping plate 11 and used for the movement of the connecting column 23.

The second motor 22 located on one side of the movable plate 10 is arranged on the top of the movable block 8, and moves with the movable block 8. When the movable block 8 slides along the first transmission screw 6, it drives the second motor 22 and the support frame 20 to move, so that the power supply shell 2 can be clamped and fixed under the cooperation of the first clamping plate 4 and the second clamping plate 11. The side wall of the support seat 1 is provided with a guide groove 25 connected to the mounting groove 5. The inner bottom wall of the mounting groove 5 and located below the first transmission screw 6 are provided with an inclined chip guide plate 26. When drilling a hole in the power supply shell 2, the debris on the power supply shell 2 falls into the mounting groove 5 along the strip groove 9, and then is guided out along the chip guide plate 26 and the guide groove 25.

[0033] The working principle and use process of the utility model are as follows: when using the device, the power supply housing 2 is first inserted into the support housing 13 so that one end thereof contacts the first clamping plate 4, and then the first transmission screw 6 is driven to rotate by the first motor 7, driving the movable block 8, the movable plate 10 and the second clamping plate 11 to slide toward the side close to the power supply housing 2, so that the support rod 14 is inserted into the inside of the power supply housing 2 along the other side of the power supply housing 2, and the power supply housing 2 is fixed with the cooperation of the second clamping plate 11, and the support plate 16 is driven to move by controlling the electric telescopic rod 15. It moves until it contacts the inner bottom wall and the inner top wall of the power supply casing 2 to support it so as to prevent the power supply casing 2 from deforming during the drilling process. When it is necessary to support power supply casings 2 of different sizes, the second transmission screw 21 is driven to rotate by the second motor 22, and the slider 24, the connecting column 23 and the support casing 13 or the support rod 14 are driven to move to match the size of the power supply casing 2. When drilling the power supply casing 2, the debris on the power supply casing 2 falls into the mounting groove 5 along the strip groove 9, and is then discharged along the chip guide plate 26 and the outlet groove 25.
