Description

Technical Field

[0001] The present application relates to the technical field of positioning tooling, and in particular to a drilling positioning device. Background Art

[0002] There are many holes on the white body of a car, which are used as process holes, vias, mounting holes, etc. In the small-batch trial production and design verification stage of the white body, it is sometimes inevitable to add holes or change the position of holes on the parts. In the related technology, it is generally solved by marking or making a simple punching die. Marking requires manual marking of the hole position, and then drilling with a drill bit aligned with the marked position, which has the disadvantages of large workload and difficulty in ensuring consistency.

[0003] A method for making a simple punching die, for example, a design method for a new hole positioning tool disclosed in a Chinese patent with publication number CN102528785A, includes a hole positioning tool and two clamps. The hole positioning tool is an "L-shaped" plate structure. The two surfaces of the "L-shaped" plate are a hole surface and a non-hole surface. Clamps are respectively installed at the left and right ends of the hole surface. The hole surface is marked and drilled according to the size on the drawing; the hole positioning tool is fixed to the frame beam by the clamp. When in use, the non-hole surface of the hole positioning tool is used to be pressed against the upper (or lower) wing surface of the frame beam to complete the hole positioning in the height direction of the frame beam. According to the requirements of the drawing, the positioning point of the key hole along the length direction of the frame is found on the hole surface of the hole positioning tool. The hole positioning tool is fixed to the frame beam by two clamps according to the design positioning reference, and then the sample punch and hammer are used to complete the nailing of the sample punch on the frame beam according to the small hole on the hole positioning tool.

[0004] However, the method of making a simple punching die sometimes requires the use of a punching machine to achieve punching. The punching machine is expensive and occupies a large area. Some OEMs do not have a small punching machine, so the implementation cycle is long and the cost is high. Utility Model Content

The drill sleeve 32 corresponds to the drill hole 24 one by one, and the corresponding drill sleeve 32 coincides with the axis center line of the drill hole 24.

[0050] The jig pressing plate 31 and the positioning plate 23 are respectively disposed on two sides of the workpiece 100 .

[0051] During the small-batch trial production and design verification phase of automobile body-in-white, it is sometimes inevitable to add holes to parts or change the positions of holes.

[0052] The drilling positioning device provided in the embodiment of the present application is provided with a positioning mechanism 2, and at least one drill hole 24 is provided on the positioning plate 23 of the positioning mechanism 2; and the drilling jig 3 is detachably connected to the positioning mechanism 2, so that at least one drill sleeve 32 is provided on the drilling jig pressing plate 31 of the drilling jig 3, and the drill sleeve 32 corresponds to the drill hole 24 one by one, so that when it is necessary to drill a part, as long as the plane structure of the added hole or the hole whose position is changed is the same, the drilling position can be positioned with the help of the drilling positioning device of this embodiment, and then it is convenient for the operator to align the drill bit of the bench drill equipment or hand drill tool with the drill sleeve 32, so that the drill sleeve 32 plays a guiding role, and after drilling the workpiece 100, the drill bit can be passed through the drill hole 24, which is convenient for rapid drilling, fast positioning, low cost, high efficiency and high precision. There is no need for manual marking, easy operation, and no need to make a simple punching die and then use a punching machine to achieve punching. The implementation cycle of adding or changing the hole position is short, which greatly reduces the cost.

[0053] It should be noted that the workpiece 100 in this embodiment can be a structural member of the same type or a structural member having certain identical features. By placing the workpiece 100 on the positioning plate 23, the workpiece 100 can be quickly positioned. The positioning mechanism 2 of this embodiment can position a variety of different workpieces 100 of the same type or having certain identical features, thereby improving versatility.

[0054] In some embodiments, in combination Figure 3 As shown, the positioning plate 23 is further formed with a clearance portion 25, which corresponds to the protruding structure formed on the workpiece 100 to make way for the protruding structure of the workpiece 100. The protruding structure formed on the workpiece 100 and capable of being accommodated in the clearance portion 25 is a certain common feature of a plurality of different workpieces 100.

[0055] By making the giving way portion 25 correspond to the raised structure formed on the workpiece 100, a giving way is formed for the raised structure of the workpiece 100, so that the workpiece 100 and the positioning plate 23 can be quickly assembled. The giving way portion 25 can not only play a giving way role, but also play a role in quickly aligning the giving way portion 25 and the workpiece 100, which facilitates rapid positioning and has high assembly efficiency.

[0056] In some embodiments, in combination Figure 3 , Figure 4 As shown, the positioning mechanism 2 further includes a jig fixing portion 26, and the jig fixing portion 26 is provided with a jig positioning hole 27;

[0057] The drilling jig 3 is fixedly connected with a positioning pin 33 , which penetrates into the drilling jig positioning hole 27 so that the axis of the drill sleeve 32 coincides with the axis of the drill through hole 24 .

[0058] In order to facilitate the rapid fixation of the drill jig 3 to the positioning mechanism 2, a drill jig fixing portion 26 is provided on the positioning mechanism 2, and a drill jig positioning hole 27 is opened in the drill jig fixing portion 26; and a positioning pin 33 is correspondingly provided on the drill jig 3, and the positioning pin 33 is inserted into the drill jig positioning hole 27, so that the drill jig 3 and the positioning mechanism 2 can be quickly assembled, and after the positioning pin 33 is inserted into the drill jig positioning hole 27, it can ensure that the drill sleeve 32 coincides with the axial center line of the drill bit through hole 24, thereby facilitating subsequent drilling operations, which is convenient and quick.

[0059] In some embodiments, in combination Figure 3 As shown, the positioning mechanism 2 further includes: a support seat 21, the support seat 21 is arranged relatively below the positioning plate 23;

[0060] The elevated portion 22 is connected between the support base 21 and the positioning plate 23 .

[0061] By providing the elevated portion 22, the positioning plate 23 can have a certain height, so as to reserve space for the arrangement of the workpiece 100. Figure 1 As shown, the workpiece 100 sometimes has a relatively long flange, and the surface to be punched is not in the same plane as the flange. In this case, sufficient space needs to be reserved for the arrangement of the flange, so as to facilitate the placement of the punching surface on the positioning plate 23 to avoid interference.

[0062] In some embodiments, in combination Figure 4 As shown, the drill template pressing plate 31 is provided with a through hole, and the drill sleeve 32 is sleeved in the through hole.

[0065] In some embodiments, in combination Figure 4 As shown, the end of the locating pin 33 facing the jig locating hole 27 is configured to be tapered to provide guidance when the locating pin 33 penetrates into the jig locating hole 27 .

[0066] By configuring the end of the locating pin 33 facing the jig locating hole 27 to be tapered, the locating pin 33 can be guided by the tapered structure when it passes through the jig locating hole 27, thereby facilitating the alignment of the locating pin 33 with the jig locating hole 27 and improving assembly efficiency.

[0067] Specifically, the positioning pin 33 is screwed onto the drilling template plate 31 using standard parts.

[0068] In some embodiments, in combination Figure 3 As shown, there are two jig fixing parts 26 , and the two jig fixing parts 26 are respectively disposed on both sides of the positioning plate 23 .

[0069] Therefore, after the positioning pin 33 passes through the jig positioning hole 27, the two jig fixing parts 26 limit the jig 3 to prevent the jig 3 from twisting, thereby improving the positioning accuracy and ensuring the stability of subsequent drilling.

[0070] In some embodiments, in combination Figure 1 , Figure 2 As shown, the drilling positioning device also includes: a base 1, and a positioning mechanism 2 is fixedly installed on the base 1.

[0071] The base 1 can support and fix the positioning mechanism 2, increase the force-bearing area of ​​the positioning mechanism 2, improve the stability of the positioning mechanism 2, and avoid the positioning mechanism 2 from tilting or overturning due to shaking during the drilling process.

[0072] Additionally, the base 1 can be fixed on a bench drill, thereby facilitating cooperation with the bench drill.

[0073] In some embodiments, in combination Figure 2 As shown, the base 1 includes: a support platform 12, on which a positioning mechanism mounting hole 14 is opened;

[0074] The fixed bottom plate 11 is fixed at a relatively lower part of the support platform 12 . The fixed bottom plate 11 is provided with a plurality of fixed slots 13 . The base 1 is fixed to the external structure via the fixed slots 13 .

[0075] The support platform 12 is provided with a positioning mechanism mounting hole 14, and the support seat 21 of the positioning mechanism 2 is provided with a plurality of mounting holes. By aligning the positioning mechanism mounting hole 14 with the mounting holes, the support platform 12 and the positioning mechanism 2 can be screwed together with standard parts, thereby fixing the positioning mechanism 2 on the base 1.

[0076] The fixed bottom plate 11 of the base 1 is fixed relatively below the support platform 12, and the fixed bottom plate 11 is provided with a plurality of fixed slots 13, so that the base 1 can be fixed to the bench drill via the fixed slots 13, which is convenient and fast and improves the fixing efficiency.

[0077] The specific working mode of the drilling positioning device provided in the embodiment of the present application is described as follows:

[0078] Take the drilling tool as an electric hand drill as an example.

[0079] In the first step, the workpiece 100 is placed on the positioning plate 23 of the positioning mechanism 2 , and preliminary positioning is performed through the cooperation between the profile of the workpiece 100 and the clearance portion 25 .

[0080] The second step is to place the jig 3 and insert the positioning pin 33 into the jig positioning hole 27 so that the jig pressing plate 31 and the positioning plate 23 are respectively arranged on both sides of the workpiece 100, and at the same time, the drill sleeve 32 and the drill through hole 24 are quickly aligned.

[0081] The third step is to insert the drill bit of the drilling tool into the drill sleeve 32 to drill a hole.

[0082] Additionally, if the drilling tool is a bench drill, before starting the first step, the following steps may be performed: fixing the base 1 to the working surface of the bench drill via the fixing slot 13 on the base 1 to ensure that the relative position of the workpiece 100 and the drill bit of the bench drill remains unchanged.

[0083] The drilling positioning device provided in the embodiment of the present application is easy to install, simple to operate, has high positioning accuracy, low cost, and high efficiency. It can meet the requirements for adding or changing hole positions in small-batch trial production and design verification stages of body parts, and can also be used as a processing method for adding or changing holes in body parts in the mass production stage.
