TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical processing, in particular to a drilling positioning device. BACKGROUND

[0002] In the production process of motor train units and ordinary passenger cars, drilling problems often occur. In actual operation, the method of measuring the size and marking the hole position with a marking line is often used to find the positioning size of the hole. However, this method is very time-consuming, and the positioning accuracy cannot be guaranteed, which may cause hole position deviation during part installation, causing great trouble to production operation and wasting company resources.

[0003] Currently, two methods are used for drilling positioning in the prior art. One is to use a box ruler to measure according to the size on the drawing, and then mark the drilling position with a line. The other method is to use a template for drilling positioning.

[0004] For the first drilling positioning method, line marking errors often occur, which causes irreparable problems and affects the overall appearance of the car body. In addition, this method is low in efficiency and wastes a lot of working hours.

[0005] For the second drilling positioning method, the main problem is that this template is only suitable for this batch of vehicles, and when the production vehicle is changed, it is no longer applicable, which wastes a lot of materials.

[0006] Therefore, a drilling positioning device with simple structure, light weight, and adjustable is needed to overcome the problems in the prior art. SUMMARY

[0007] The technical problem to be solved by the present application is to provide a drilling positioning device with the advantages of more accurate positioning, rapid positioning of the drilling positioning size according to different positioning size requirements, reduction of waste of raw materials due to the inability to change the type, and flexibility.

[0008] To solve the above technical problems, the technical scheme adopted by the present application is:

[0009] A drilling positioning device, comprising a plurality of corner connecting pieces, a plurality of hole positioning pieces, a plurality of frame assemblies, and a plurality of connecting pieces.

[0010] The frame assembly comprises two groups of mirror image profiles with a gap therebetween, and a plurality of fixed holes are formed in the profiles in a spaced-apart manner and distributed along the length direction of the profiles; a plurality of locking holes are formed in the side edges of the profiles in a spaced-apart manner and distributed along the length direction of the profiles.

[0011] The corner connector includes a body and two connecting ears corresponding to the number of profiles. The body is a rectangular hollow structure. The connecting ears are arranged in pairs on one side of the body. The connecting ears are fixed by connecting parts through locking holes.

[0012] The hole positioning component has a locking hole and a first positioning hole corresponding to the two sets of profile fixing holes. The positioning hole is located in the middle of the locking hole and corresponds to the interval between the profiles. The locking hole and the fixing hole are fixed by a connecting component.

[0013] Preferably, it further includes two cover plates, which are connected to both ends of the body.

[0014] Preferably, the cover plate is a rectangle corresponding to the body, and a second positioning hole is provided at the four corners of the cover plate. The body is provided with mounting holes corresponding to the second positioning holes, and the mounting holes and the second positioning holes are fixed by connecting parts.

[0015] Preferably, the profile has a cavity for accommodating the connecting ear.

[0016] Preferably, it also includes an intermediate connector. The frame assembly consists of multiple sets, and the profiles of two adjacent sets of the frame assembly are connected by the intermediate connector. The intermediate connector has multiple connection holes, and the connection holes and locking holes are fixed by a connecting sub-part.

[0017] Preferably, the intermediate connector and connecting component are made of low-carbon steel;

[0018] The corner connectors, hole positioning parts, and frame components are made of aluminum alloy.

[0019] Preferably, the connecting component is a bolt.

[0020] The beneficial effects of this invention are as follows: the main function of the hole positioning component is to connect the inner and outer frame profiles with bolts. At the same time, the hole positioning component has a positioning hole in the center, which can be used to accurately position the installation component by electric drill. The hole positioning component can slide on the frame profile according to the actual position of the positioning hole and can be fixed by connecting parts. In this way, the correct positioning size can be adjusted to complete the hole positioning and drilling operation. In addition, this device can be arbitrarily combined, can achieve the characteristics of quick changeover, and can avoid material waste. Attached Figure Description

[0025] Please refer to Figure 1 as well as Figure 2 A drilling positioning device includes several corner connectors 1, several hole positioning components 2, several frame assemblies, and several connecting parts 4.

[0026] The frame assembly includes two sets of mirror-arranged profiles 3 with a gap 5 between them. The top and bottom of the profiles 3 are respectively provided with a plurality of fixing holes 6 spaced 5 apart and distributed along the length of the profiles 3. The side of the profiles 3 is provided with a plurality of locking holes 7 spaced 5 apart and distributed along the length of the profiles 3.

[0027] The corner connector 1 includes a body 8 and two connecting ears 9 corresponding to the number of profiles 3. The body 8 is a rectangular hollow structure. The connecting ears 9 are arranged in pairs on one side of the body 8. The connecting ears 9 are fixed by connecting parts 4 in cooperation with the locking holes 7.

[0028] The hole positioning component 2 is provided with a lock hole 10 and a first positioning hole 11 corresponding to the two sets of profile 3 fixing holes 6. The positioning hole is located in the middle of the lock hole 10 and corresponds to the interval 5 between the profiles 3. The lock hole 10 and the fixing hole 6 are fixed by the connecting component 4.

[0029] As described above, the main function of the hole positioning component 2 is to connect the inner and outer frame profiles 3 with bolts. The hole positioning component 2 has a positioning hole in the center, which can be used to accurately position the installation component by electric drill. The hole positioning component 2 can slide on the frame profile 3 according to the actual position of the positioning hole and can be fixed by the connecting part 4. In this way, the correct positioning size can be adjusted to complete the hole positioning drilling operation. At the same time, this device can be arbitrarily combined, can achieve the characteristics of quick changeover, and can avoid material waste.

[0030] Furthermore, it also includes two cover plates 12, which are connected to both ends of the body 8.

According to the specific size of the hole, the hole positioning part 2 can be installed on the closely spaced threaded holes on the upper surface of the profile 3. This can accurately complete the hole positioning.

[0040] Second, connect the frame profile 3 of the assembly number to the corner connector 1. The corner connector 1 is hollow in the middle, and holes can be drilled in the matching cover plate 12 according to the actual position of the corner hole.

[0041] Third, according to the actual drilling position, install the hole positioning part 2 to the designated position, which is the drilling position.
