Detailed implementation manners

[0033] The core of the present utility model is to provide a drilling positioning tooling for the buckle seat of an open car locking device, which can clamp multiple buckle seats at one time without inclination.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "middle", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0036] In a specific implementation manner of the present utility model, as Figures 1 to 12 shown, it includes:

[0037] Seat body 1, the seat body 1 is fixedly connected to the working platform 9 of the machine tool. A plurality of mounting grooves 101 are evenly arranged at intervals along the length direction of the top surface of the seat body 1. The mounting grooves 101 are matched with the buckle seats 2. The buckle seats 2 are installed in the mounting grooves 101, and the hinge grooves 201 of the buckle seats 2 are arranged upwards, and the length direction of the mounting grooves 101 is perpendicular to the length direction of the seat body 1;

[0038] Pressing strip 3, the pressing strip 3 is located above the hinge groove 201, and the bottom surface of the pressing strip 3 presses on the bottom walls of the hinge grooves 201 of all the buckle seats 2;

[0039] Vertical driving assembly, the vertical driving assembly is arranged on the seat body 1, and the working end of the vertical driving assembly presses on the top surface of the pressing strip 3. The number of the vertical driving assemblies is less than the number of the mounting grooves 101.

[0040] Specifically, by restricting the six degrees of freedom of the buckle seat 2 through the installation groove 101 and the pressing strip 3, the buckle seat 2 is tightly pressed and positioned, without tilting or skewing, ensuring the drilling accuracy, and the positioning process is convenient and fast; the number of vertical driving components can be 0.3 to 0.5 times that of the installation groove 101. When the result is not an integer, it is rounded up. Since the number of vertical driving components is less than that of the installation groove 101, in essence, it is less than the number of buckle seats 2 installed on the seat body 1. Then the number of times the staff operates the vertical driving components is less than the number of buckle seats 2, thus correspondingly reducing the labor intensity of the staff and improving the production efficiency; through the arrangement of multiple installation grooves 101 and pressing strips 3, multiple buckle seats 2 can be clamped at the same time, without the need for the staff to repeatedly clamp and disassemble, reducing the labor intensity of the staff and improving the production efficiency.

[0041] In some embodiments, a through groove 102 is formed in the top surface of the seat body 1, the through groove 102 penetrates through both ends of the seat body 1, the depth of the through groove 102 is greater than or equal to the depth of the installation groove 101, the through groove 102 is correspondingly formed with the hinge groove 201, and the pressing strip 3 is located in the through groove 102; the vertical driving component includes a stud 4 and a pressing block 5. There are multiple studs 4, the studs 4 are vertically arranged, the bottom end of the stud 4 is fixedly connected to the bottom wall of the through groove 102, the top end of the stud 4 protrudes out of the pressing strip 3, and the pressing block 5 is threadedly connected to the top end of the stud 4. The bottom surface of the pressing block 5 is the working end of the vertical driving component.

[0042] Specifically, press the pressing strip 3 forcefully, then the pressing strip 3 presses the buckle seat 2, and then turn the pressing block 5, the pressing block 5 presses the pressing strip 3, and then the buckle seat 2 is tightly pressed.

[0043] In some embodiments, one end of the pressing strip 3 protrudes out of the through groove 102, a pair of support ears 103 are fixed at one end of the seat body 1, a strip-shaped through hole 104 is formed in the support ears 103, the length direction of the strip-shaped through hole 104 is the vertical direction, a limiting rod 6 is movably mounted on the two strip-shaped through holes 104, and the end of the pressing strip 3 protruding out of the through groove 102 is located between the two support ears 103 and the limiting rod 6 penetrates through the pressing strip 3; the pressing block 5 is strip-shaped, and an avoidance opening 301 for the pressing block 5 to pass through is formed in the pressing strip 3, and the width dimension of the avoidance opening 301 is greater than or equal to the width dimension of the pressing block 5.

[0044] Specifically, the limiting rod 6 can prevent the pressing strip 3 from being accidentally lost. Turn the pressing block 5 so that its length direction is consistent with the length direction of the seat body 1, then the pressing block 5 can pass through the avoidance opening 301 when the pressing strip 3 swings; the setting of the strip-shaped through hole 104 enables the limiting rod 6 to move up and down. Then when the pressing strip 3 is pressed forcefully, the pressing strip 3 can move downward, thus not affecting the pressing strip 3 to press the buckle seat 2; press the pressing strip 3 forcefully, then the pressing strip 3 presses the buckle seat 2, and then turn the pressing block 5, and both ends of the pressing block 5 press the pressing strip 3, then the buckle seat 2 is tightly pressed.

[0045] In some embodiments, a rubber pad 7 is fixed on the bead 3, and the rubber pad 7 is located between the bottom surface of the bead 3 and the hinge groove 201.

[0046] Specifically, the thickness of the rubber pad 7 is 3 to 10 millimeters. The rubber pad 7 is used to prevent the bead 3 from directly pressing on the buckle seat 2, resulting in indentations on the buckle seat 2. And because the rubber pad 7 has elasticity, it can ensure that both ends of the pressing block 5 can press on the bead 3. That is, if the bottom surface of the pressing block 5 is flush with the top surface of the bead 3 and its length direction is the same as the length direction of the avoidance opening 301, then the pressing block 5 cannot press on the bead 3. At this time, the force pressing on the bead 3 can be increased, and then the pressing block 5 is rotated continuously so that the length direction of the pressing block 5 forms an angle of 30° to 90° with the length direction of the avoidance opening 301.

[0047] In some embodiments, an avoidance hole 105 for avoiding the drill bit is provided on the bottom wall of the installation groove 101, and / or a chip discharge hole 106 is provided on the bottom wall of the through groove 102. Both the avoidance hole 105 and the chip discharge hole 106 penetrate the bottom wall of the seat body 1.

[0048] Support feet 107 are fixed at the four corner positions of the seat body 1, and there is a gap between the bottom surface of the support feet 107 and the bottom surface of the seat body 1.

[0049] Specifically, the avoidance hole 105 is used to avoid the bottom end of the drill bit to ensure that the drill bit can penetrate the buckle seat 2. When the staff cleans the debris in the installation groove 101 and the through groove 102, the debris can be discharged from the chip discharge hole 106 and fall on the workbench 9. Since there is a gap between the bottom surface of the support feet 107 and the bottom surface of the seat body 1, there is a gap between the bottom surface of the seat body 1 and the workbench 9, so the staff can push out the debris that has fallen on the workbench 9.

[0050] In some embodiments, sliders 8 are slidably connected in two sliding grooves of the workbench 9. The sliders 8 are arranged in one-to-one correspondence with the support feet 107. A pull rod 10 is vertically fixed on the top surface of the slider 8. The top end of the pull rod 10 penetrates through the support feet 107 and is threadedly connected with a lock nut 11. The top surface of the slider 8 is lower than the top surface of the workbench 9, and the support feet 107 support on the top surface of the workbench 9.

[0051] Specifically, the workbench 9 belongs to the prior art, and multiple sliding grooves are provided on its top surface. The method of fixing the seat body 1 is similar to the method of fixing a bench vice in the prior art, that is, the seat body 1 is fixed on the workbench 9 by tightening the lock nut 11.

[0052] Working principle of a drilling positioning tooling for the buckle seat of an open wagon locking device of the present utility model: Open the pressing strip 3, sequentially place a plurality of buckle seats 2 into the installation groove 101, turn the pressing block 5 so that its length direction is consistent with the length direction of the seat body 1, rotate the pressing strip 3, then when the pressing strip 3 swings, the pressing block 5 can pass through the avoidance opening 301, and then the pressing strip 3 will rest on the hinge groove 201. When pressing the pressing strip 3 forcefully, the arrangement of the strip-shaped through hole 104 enables the limiting rod 6 to move up and down, and the pressing strip 3 can move downward, thus not affecting the pressing strip 3 to press the buckle seat 2. Then turn the pressing block 5, and both ends of the pressing block 5 press the pressing strip 3, then the buckle seat 2 is pressed and positioned; by restricting the six degrees of freedom of the buckle seat 2 through the installation groove 101 and the pressing strip 3, the buckle seat 2 is pressed and positioned without tilting or skewing, ensuring the drilling accuracy, and the positioning process is convenient and fast. After drilling, loosen the pressing block 5 so that its length direction is consistent with the length direction of the seat body 1, then rotate the pressing strip 3, then open the pressing strip 3, and then the buckle seat 2 in the installation groove 101 can be taken out.

[0053] The number of vertical driving components is less than the number of installation grooves 101, and thus it is essentially less than the number of buckle seats 2 installed on the seat body 1. Then the number of times the staff turns the pressing block 5 is less than the number of buckle seats 2, correspondingly reducing the labor intensity of the staff and improving the production efficiency; through the arrangement of a plurality of installation grooves 101 and pressing strips 3, a plurality of buckle seats 2 can be installed and clamped simultaneously, without the need for the staff to repeatedly install and disassemble, reducing the labor intensity of the staff and improving the production efficiency.

[0054] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other, and the embodiments can be combined with each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0055] The above embodiments are only descriptions of the preferred modes of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
