[0002] When drilling holes in the brake base plate, the base plate and a plurality of pressure blocks are generally used for fixing. The Chinese utility model patent with publication number CN217343709U publicly authorized a brake base plate drilling fixture, which constructs a basic limiting structure by setting a stepper motor, a screw rod, a moving block, a fixed block and a limiting plate; further, the stepper motor is used to drive the screw rod and the moving block to move along the screw rod axial direction, and the fixed block and the limiting block are moved, thereby effectively adjusting the position of the brake base plate, so that the position of the brake base plate is adjusted in place, avoiding repeated clamping.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] In order to solve the technical problem of low feeding efficiency, the utility model provides a brake base plate drilling fixture, which can improve the feeding efficiency.

[0028] It should be noted that the brake base plate drilling fixture described in the utility model is used for but not limited to brake base plates, etc. For the convenience of explanation, in the utility model, only a brake base plate drilling fixture applied to a brake base plate drilling device is used as an example for explanation, and the principle of applying a brake base plate drilling fixture to other types of equipment is essentially the same as the principle applied to the brake base plate clamping equipment, which will not be elaborated here.

[0029] See also Figure 1 - Figure 6 ,in Figure 1 This is a structural schematic diagram of a brake base plate drilling fixture in an embodiment of the utility model, a brake base plate drilling fixture, including a base plate 100, a reducing ring 200 and a fastener 300; a limiting column 110 is provided in the top center of the base plate 100, and positioning holes 120 are provided on both sides of the limiting column 110, and the two positioning holes 120 are arranged diagonally; the reducing ring 200 is sleeved on the outside of the limiting column 110; the fastener 300 is adapted to the positioning hole 120, and the fastener 300 corresponds to the positioning hole 120 one by one.

[0030] In this embodiment, the brake base plate can be sleeved by setting the limit column 110 to complete the rough positioning of the brake base plate; then, the axial displacement of the brake base plate is limited by the fastener 300 and the two diagonally arranged positioning holes 120, thereby completing the complete limitation of the brake base plate. The above clamping is convenient and simple, and can effectively improve the feeding efficiency. In particular, the design of the reducer ring 200 can complete the limitation of brake base plates of different specifications, effectively avoiding the problem of repeated clamping caused by the need to limit brake base plates of different specifications.

[0031] In one embodiment, see Figure 1 The positioning holes 120 are arranged in groups, each group is evenly distributed along the diagonal of the bottom plate 100, and different groups are arranged on both sides of the limiting column 110. Each group of positioning holes 120 is adapted to at least one fastener 300.

[0032] In this embodiment, by providing the positioning holes 120 at diagonal angles, the number of fasteners 300 can be minimized to limit the position of the brake base plate, which saves costs and complies with the principle of process optimization.

[0033] In one embodiment, see Figure 1 , the fastener 300 is configured as a fastening bolt 310 .

[0034] In this embodiment, the fastening bolt 310 can be positioned through the positioning holes on the brake base plate.

[0035] In one embodiment, see Figure 1 , Figure 6 , the fastener 300 is configured as a pressing plate 320 .

[0036] In this embodiment, the pressure plate 320 can be threadedly connected to the positioning hole 120 and pressed on the top end surface of the brake base plate by continuous rotation, thereby fixing the brake base plate.

[0037] In one embodiment, see Figure 1 , Figure 3 The limiting column 110 is cylindrical, and a limiting groove 111 is formed around the outer wall of the limiting column 110 . A limiting block 210 is formed around the inner wall of the reducing ring 200 . The limiting blocks 210 are used to extend into each limiting groove 111 one by one and adapt to the limiting groove 111 .

[0038] In this embodiment, the reducing ring 200 is limited by the connection between the limiting block 210 and the limiting groove 111 .

[0039] In one embodiment, see Figure 1 The outer wall of the limiting column 110 is provided with chamfers 112 all around.

[0040] In this embodiment, the design of the chamfer 112 allows the placement of the brake base plate and the reducer ring 200 to be smoother.

[0041] In one embodiment, see Figure 1 , Figure 4 The bottom plate 100 is in an inverted T-shaped structure, and through holes 130 are respectively opened on both sides of the top of the bottom plate 100, and positioning bolts 140 are arranged in the through holes 130.

[0042] In this embodiment, the combination design of the through hole 130 and the positioning bolt 140 can enable the bottom plate 100 to be fixed on the work surface.

[0043] In one embodiment, see Figure 1 The outer wall of the bottom plate 100 is provided with a clearance groove 150 .

[0044] In this embodiment, the clearance groove 150 facilitates the discharge of iron chips after drilling.

[0045] In one embodiment, see Figure 1 The notch of the easing groove 150 is provided with an inclined surface 151 .

[0046] In this embodiment, the inclined surface 151 helps to discharge the iron filings and avoid accumulation.

[0047] In one embodiment, see Figure 3 A plurality of chip removal grooves 160 are formed on the top of the bottom plate 100 , and the chip removal grooves 160 are connected to the clearance grooves 150 .

[0048] In this embodiment, the iron chips after drilling can enter the clearance groove 150 through the chip discharge groove 160 and be discharged.

[0049] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the utility model is described in detail:

[0050] First, insert the positioning bolt 140 into the through hole 130 and fix it to the work surface; then, insert the inner hole of the brake base plate onto the limiting column 110 to complete the rough positioning of the brake base plate; then, select the corresponding positioning hole 120 according to the specifications of the brake base plate and insert the fastening bolt 310 into the positioning hole of the brake base plate to complete the complete definition of the brake base plate (here, the pressure plate 320 can also be used to define the brake base plate); then, start the equipment to drill holes in the brake base plate. Due to the combined design of the limiting column 110 and the reducing ring 200, the brake base plate can be conveniently and quickly roughly positioned, and can adapt to the clamping of brake base plates of different specifications. Then, the brake base plate can be clamped using two diagonally arranged fastening bolts 310, which effectively improves the overall feeding efficiency and has a simpler structure.

[0051] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model.
