Description

Technical Field

[0001] The utility model relates to the technical field of punching processing equipment, in particular to a punching clamping device for preventing position deviation of power electronic components. Background Art

[0002] Punching is a critical process step in the production of power electronic components. However, due to the diverse sizes and shapes of power electronic components and their varying material properties, positional shifting often occurs during the punching process. This shift not only affects the subsequent assembly and use of the components, but also reduces production efficiency and increases production costs. Therefore, developing a clamping device that can effectively prevent positional shifting of power electronic components during the punching process is crucial.

[0003] The reference patent name is a punching clamping device for preventing position displacement of power electronic components (publication number CN217891124U). By setting a clamping plate, a connecting plate, a screw rod, a pressing plate, a rubber protrusion, a connecting shaft, a movable groove, a second gear and a second rack, the components to be punched can be doubly clamped and fixed, increasing the stability during punching, thereby ensuring that the components will not be displaced during punching, and thus improving the accuracy of punching.

[0004] Based on the above patent, although the punching and clamping equipment for power electronic components in the prior art can achieve stable clamping of them in all directions to ensure that they do not shift, for some electronic components with irregular shapes, they are prone to slipping on their irregular surfaces during the clamping process, which in turn affects the processing effect. For this reason, the utility model provides a punching and clamping equipment that prevents the position of power electronic components from shifting. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a punching and clamping device that prevents the position of power electronic components from shifting, solving the problem that the previous punching and clamping equipment is prone to slipping on the irregular surfaces during the clamping process when processing some irregularly shaped electronic components, thereby affecting the processing effect.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A punching and clamping device for preventing positional displacement of power electronic components comprises a processing table, wherein a clamping mechanism is provided at the upper end of the processing table, and the clamping mechanism comprises:

[0007] Two sets of symmetrically distributed multi-point extrusion components are arranged at the upper end of the processing table, including a mounting plate fixed to the upper end of the processing table, and a plurality of sets of telescopic rods are embedded and fixed on the mounting plate, and one side of the plurality of sets of telescopic rods is interconnected and connected to an oil injection block;

[0008] The constant pressure assembly is arranged on the upper part of the multi-point extrusion assembly and is used to control the oil pressure inside the oil injection block and the telescopic rod;

[0009] The oil pump assembly is arranged at the upper end of the processing table and is used to pump oil into the inner cavity of the oil injection block.

[0010] Preferably, the constant pressure assembly includes an internal pressure seat fixed to the upper end of the oil injection block, and the oil injection block and the internal cavity of the internal pressure seat are communicated with each other.

[0011] Preferably, a sliding plug is slidably provided on the inner wall of the inner pressure seat, and a compression spring is connected between the sliding plug and the top end of the inner pressure seat, and a liquid guide tube is interconnected at one end of the inner pressure seat.

[0012] Preferably, the oil pump assembly includes an oil storage tank fixed to the upper end of the processing table, and an oil pump pipe is provided at the upper end of the oil storage tank, and a pump is installed on the oil pump pipe to pump the oil in the oil storage tank into the pipeline.

[0013] Preferably, one end of the oil filling block is connected to the oil storage tank through a drain pipe, and a valve body is installed on the drain pipe.

[0014] Preferably, the telescopic rod includes a sleeve fixed on the mounting plate, and a sealing plate is slidably installed on the inside of the sleeve, and a sliding rod is fixed to one end of the sealing plate extending to the outside of the sleeve, and a limiting portion that conflicts with the sealing plate is integrally formed at the pipe mouth end of the sleeve, and a drilling structure is provided at the upper end of the processing table.

[0015] Beneficial effects

[0016] The utility model provides a punching and clamping device for preventing positional displacement of power electronic components. Compared with the prior art, it has the following advantages:

[0017] (1) The punching and clamping device for preventing the position displacement of power electronic components is designed with a multi-point extrusion assembly. In the initial state, the telescopic rod is in an unextended state, and the end of the slide rod does not contact the power electronic component. When the power electronic component needs to be fixed on the processing table, the pump is started and the oil in the oil storage tank is pumped into the inner cavity of the oil filling block through the pump oil pipe. As the oil is injected, the oil pressure gradually increases and flows into the interior of the telescopic rod. As the oil pressure continues to act, the oil pressure in the telescopic rod pushes the sealing plate to move toward the outside of the sleeve, thereby driving the slide rod to extend until the end of the slide rod is in close contact with the power electronic component and exerts sufficient clamping force. Since the multi-point extrusion assembly is symmetrically distributed, it can ensure that the power electronic component is subjected to uniform and stable clamping force in multiple directions, and can adapt to various types of irregularly shaped electronic components.

[0018] (2) The punching and clamping device for preventing the position displacement of power electronic components is designed with a constant pressure component. The oil pressure is transmitted to the inner pressure seat through the oil filling block, pushing the sliding plug to slide on the inner wall of the inner pressure seat. Since a compression spring is connected between the sliding plug and the top end of the inner pressure seat, when the oil pressure reaches a preset value, the height of the sliding plug exceeds the liquid guide tube channel, thereby draining the oil from the liquid guide tube, maintaining the oil pressure at a preset pressure level, and avoiding excessive clamping force to damage the electronic components.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4The utility model provides a technical solution: a punching and clamping device for preventing the position displacement of power electronic components, comprising a processing table 1, a clamping mechanism 2 is provided at the upper end of the processing table 1, and the clamping mechanism 2 comprises: two groups of symmetrically distributed multi-point extrusion components 21, which are arranged at the upper end of the processing table 1, including a mounting plate 211 fixed to the upper end of the processing table 1, and a plurality of groups of telescopic rods 212 are embedded and fixed on the mounting plate 211, and one side of the plurality of groups of telescopic rods 212 are interconnected with oil injection blocks 213; a constant pressure component 22, which is arranged at the upper part of the multi-point extrusion component 21, and is used to control the oil pressure inside the oil injection block 213 and the telescopic rod 212; an oil pump component 23, which is arranged at the upper end of the processing table 1, and is used to pump oil into the inner cavity of the oil injection block 213.

[0026] In this embodiment, the constant pressure component 22 includes an internal pressure seat 221 fixed to the upper end of the oil filling block 213, and the oil filling block 213 is connected to the internal cavity of the internal pressure seat 221, a sliding plug 222 is provided on the inner wall of the internal pressure seat 221, and a compression spring 223 is connected between the sliding plug 222 and the internal top end of the internal pressure seat 221, and a liquid guide tube 224 is interconnected at one end of the internal pressure seat 221; the oil pressure is transmitted to the internal pressure seat 221 through the oil filling block 213, pushing the sliding plug 222 to slide on the inner wall of the internal pressure seat 221, and since a compression spring 223 is connected between the sliding plug 222 and the internal top end of the internal pressure seat 221, when the oil pressure reaches a preset value, the height of the sliding plug 222 exceeds the channel of the liquid guide tube 224, thereby draining the oil from the liquid guide tube 224.

[0027] In this embodiment, the oil pump assembly 23 includes an oil storage tank 231 fixed to the upper end of the processing table 1, and an oil pumping pipe 233 is provided at the upper end of the oil storage tank 231, and a pump 232 is installed on the oil pumping pipe 233 to pump the oil inside the oil storage tank 231 into the inside of the pipeline; when the pump 232 is started, the oil in the oil storage tank 231 is pumped into the inner cavity of the oil filling block 213 through the oil pumping pipe 233. As the oil is injected, the oil pressure gradually increases and flows into the interior of the telescopic rod 212. As the oil pressure continues to act, the oil pressure in the telescopic rod 212 pushes the sealing plate 5 to move toward the outside of the sleeve 3, thereby driving the sliding rod 4 to extend.

[0028] In this embodiment, one end of the oil filling block 213 is connected to the oil storage tank 231 through a drain pipe 234 , and a valve body is installed on the drain pipe 234 ; the valve body controls the flow of oil in the drain pipe 234 .

[0029] In this embodiment, the telescopic rod 212 includes a sleeve 3 fixed on the mounting plate 211, and a sealing plate 5 is slidably installed on the inner side of the sleeve 3, and a sliding rod 4 is fixed to the end of the sealing plate 5 extending to the outside of the sleeve 3, and a limiting portion that conflicts with the sealing plate 5 is integrally formed at the pipe mouth end of the sleeve 3, and a drilling structure 6 is provided at the upper end of the processing table 1; the sealing plate 5 conflicts with the limiting portion at the pipe mouth end of the sleeve 3 to prevent the sliding rod 4 from being separated from the sleeve 3, and the drilling structure 6 is composed of a main frame rod, a hydraulic push rod, a drilling motor and a drilling head, wherein the hydraulic push rod drives the drilling motor and the drilling part formed by the drilling head to move up and down, and the drilling motor drives the drilling head to rotate and punch.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] During operation, in the initial state, the telescopic rod 212 is in an unextended state, and the end of the slide rod 4 does not contact the power electronic components. When the power electronic components need to be fixed on the processing table 1, the pump 232 is started, and the oil in the oil storage tank 231 is pumped into the inner cavity of the oil filling block 213 through the oil pump pipe 233. As the oil is injected, the oil pressure gradually increases and flows into the telescopic rod 212. As the oil pressure continues to act, the oil pressure in the telescopic rod 212 pushes the sealing plate 5 to move toward the outside of the sleeve 3, thereby driving the slide rod 4 to extend until the end of the slide rod 4 is in close contact with the power electronic components and exerts sufficient clamping force. Since the multi-point extrusion assembly 21 is symmetrically distributed, it can ensure that the power electronic components are subjected to uniform and stable clamping force in multiple directions; the oil pressure is transmitted to the internal pressure seat 221 through the oil filling block 213, pushing the sliding plug 222 to slide on the inner wall of the internal pressure seat 221. Since a compression spring 223 is connected between the sliding plug 222 and the top end of the internal pressure seat 221, when the oil pressure reaches a preset value, the height of the sliding plug 222 exceeds the channel of the liquid guide tube 224, thereby draining the oil from the liquid guide tube 224 to maintain the oil pressure at a preset pressure level.

[0032] After the power electronic components are stably clamped, the drilling mechanism 6 is activated to punch the components. Due to the stable clamping, the power electronic components do not shift during the punching process. After punching is complete, the control valve opens the drain pipe 234, releasing the oil in the oil filling block 213 back into the oil tank 231. As the oil pressure decreases, the oil pressure in the telescopic rod 212 decreases, releasing the clamping force on the power electronic components.
