Description

Technical Field

[0001] The utility model relates to the field of clamping, in particular to a multifunctional rapid clamping drilling and milling device. Background Art

[0002] The high-voltage cabinet grounding knife is a safety protection device; when the high-voltage cabinet needs to be repaired or other operations, closing the grounding knife can reliably connect the busbar and other live parts of the high-voltage cabinet to the ground. This can ensure that during the maintenance process, even if there is an unexpected call, the current will be introduced into the ground through the grounding knife, thereby ensuring the personal safety of the maintenance personnel; the grounding knife is mainly connected to the electrical part of the high-voltage cabinet through a mechanical operating mechanism. When the grounding knife is closed, the blade of the grounding knife is in close contact with the grounding busbar, forming a good electrical path. Its grounding resistance is very small, which can make the fault current or induced current flow into the ground quickly; traditionally, the processing of grounding knives is to install, position and fix them one by one with a single fixture, and drilling and milling the grounding knives one by one will result in low efficiency and cannot be carried out in large-scale, batch and high-efficiency drilling and milling.

[0003] Chinese utility model patent CN 220260734 U discloses a self-centering fixture comprising a base plate fixedly connected to a housing; a clamping assembly comprising two opposing movable plates and a motor, the motor fixedly connected to the housing; a movable plate positioned on the base plate, the movable plates slidingly connected to the base plate, two slide holes formed in the base plate extending into the housing, the two movable plates being respectively connected to the motor in a transmission manner; two first guide rails fixedly connected to the base plate, a first groove formed in the movable plate, the first guide rail positioned within the first groove, and a first curved clamping plate fixedly connected to the movable plate, the two first curved clamping plates being arranged in opposing directions. This utility model can only clamp workpieces individually, resulting in low processing efficiency and high production costs. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the above-mentioned existing technologies and provide a multifunctional quick clamping drilling and milling device that can clamp and fix grounding knives quickly, in large quantities, efficiently and accurately, meeting the needs of fast positioning, fast fixation and batch fixation of clamped workpieces.

[0005] The utility model adopts a technical solution to solve its technical problems: this multifunctional quick-clamping drilling and milling device comprises a base plate, a support plate is provided above the base plate, support columns are fastened to the four corners of the base plate and the support plate, and a group of quick-clamping mechanisms are fixed on the support plate; the quick-clamping mechanism comprises a pair of symmetrically arranged leaning seats, the leaning seats comprise a left leaning block, a right leaning block and an outer leaning block, a slide groove opening opened on the support plate is provided between the two leaning seats, a top pressure block is inserted at the slide groove opening, the opposite side surfaces of the two top pressure blocks are first inclined surfaces, the two first inclined surfaces are "V"-shaped, a clamping block is provided between the two top pressure blocks, the two side surfaces of the clamping block are second inclined surfaces with the same inclination angle as the two first inclined surfaces and matched together, and a cylinder that drives the clamping block to move up and down is fixed on the base plate. The function of the base plate, support plate and support column here is to form an installation space between the base plate and the support plate for installing the cylinder; the function of the quick clamping mechanism here is to be used for large-scale, rapid, efficient and precise clamping and positioning of the grounding knife; the function of the positioning seat here is to be able to quickly position the three sides of the grounding knife; the function of the slide groove, top pressure block, first inclined surface, clamping block, second inclined surface and cylinder here is to enable a quick clamping mechanism to clamp two grounding knives at the same time, so that the utility model can clamp the grounding knives in large quantities, quickly and efficiently and then process them.

[0006] Further improvements are made by providing slots on both first inclined surfaces, and securing blocks that fit into the slots, respectively, on both second inclined surfaces. The slots have an angle consistent with the angle of the first inclined surfaces. The slots and securing blocks function to ensure that when the pressing block moves up and down, the pressing blocks on both sides can follow suit, allowing the pressing blocks to quickly tighten and loosen the grounding blade, making it easier to remove the grounding blade after processing.

[0007] As a further improvement, a first self-lubricating layer is provided on the engaging surfaces of the two card slots. The function of the first self-lubricating layer is to reduce friction and make the card block move smoothly in the card slot, thereby driving the top pressure block to move more smoothly and avoiding jamming. The first self-lubricating layer is made of tin bronze.

[0008] As a further improvement, exhaust holes are provided at the four corners of the chute opening. The function of the exhaust holes is that when the top pressure block moves at the chute opening, it is attached to the side wall of the chute opening. If there were no exhaust holes, the air in the chute opening would not be able to be quickly discharged when the top pressure block moves quickly, thus hindering the movement speed of the top pressure block and preventing it from moving quickly. Therefore, the exhaust holes can quickly discharge the air in the chute opening when the top pressure block moves, so that the top pressure block can move quickly.

[0009] Further improvements include a second self-lubricating layer on the chute surface at the chute opening, and a third self-lubricating layer on the first inclined surface. The second self-lubricating layer minimizes frictional resistance when the push block moves at the chute opening, preventing it from getting stuck and allowing it to move more smoothly. The second self-lubricating layer is made of tin bronze.

[0010] As a further improvement, the side ends of the two top pressure blocks are equipped with compression springs installed on the support plate and driving the two top pressure blocks to move closer to each other. The function of the compression springs here is to assist in the reset action. When the pressing block moves upward and the second inclined surface no longer presses the first inclined surface, the compression springs can be used to reset the top pressure blocks on both sides closer to each other, thereby facilitating the removal of the processed workpiece from the support seat.

[0011] The beneficial effects of the utility model are:

[0012] 1) Through the base plate, support plate and support column, an installation space can be formed between the base plate and the support plate for the placement and installation of the cylinder;

[0013] 2) Through various quick clamping mechanisms, it can be used for large-scale, fast, efficient and accurate clamping and positioning of grounding knives;

[0014] 3) The three sides of the grounding knife can be quickly positioned through the positioning seat; through the sliding groove, the top pressure block, the first inclined surface, the pressing block, the second inclined surface, and the cylinder, a quick clamping mechanism can clamp two grounding knives at the same time, so that the utility model can clamp the grounding knives in large quantities, quickly and efficiently before processing.
