Description

Technical Field

[0001] The utility model relates to the technical field of brake processing, in particular to a positioning structure for drilling equipment. Background Art

[0002] Commercial vehicles are vehicles designed and technically used to transport people and goods. They are categorized into five types: buses, trucks, semi-trailer tractors, incomplete buses, and incomplete trucks. These vehicles are characterized by their large size and weight. Consequently, they experience greater inertia during driving, placing higher demands on their braking systems.

[0003] The braking system of a commercial vehicle is different from that of a family car. Among them, the brake base plate is an important component in the braking system of a commercial vehicle. The brake base plate is an irregular pie-shaped structure. Due to the assembly requirements with other parts, the brake base plate is provided with multiple different hole positions. Among them, the center hole is opened in the central area of the brake base plate, and the cam center hole is opened on one side of the center hole. The other holes are arranged in a circular manner around the center hole. Influenced by the processing requirements and processing procedures, the center hole and the cam center hole are processed first, and then the other holes are processed. Because the number of other holes is large and the processing depth and processing angle are different, and the shape of the brake base plate is irregular, multiple different positioning tools are required to position the brake base plate in sequence, which is relatively inconvenient in actual operation.

[0007] In actual application, the center hole of the brake base plate and the center hole of the cam are used as reference holes. After aligning the reference hole with the positioning column, push the brake base plate so that the brake base plate is fully fitted with the positioning main plate. At this time, the positioning column is embedded in the reference hole of the brake base plate. At the same time, the processing hole is aligned with the hole position to be processed of the brake base plate. During the processing, the positioning main plate is driven to rotate or translate by the displacement device, and then the brake base plate is driven to move synchronously, so as to match the drilling equipment to process the holes of different processing depths and processing angles.

DETAILED DESCRIPTION

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] A positioning structure for drilling equipment includes: a positioning mainboard 1, a displacement device 2, and a clamping structure 3. The positioning mainboard 1 is an approximately rectangular structure. A positioning column 11 and a processing hole 12 are provided on the positioning mainboard 1. When it is necessary to process the hole to be processed on the brake base plate, the center hole of the brake base plate and the center hole of the cam have been processed based on the previous processing steps. Therefore, the center hole and the center hole of the cam are used as reference holes. The positioning column 11 is fixedly connected to the positioning mainboard 1 and protrudes from the surface of the positioning mainboard 1. There are two positioning columns 11, one of which corresponds to the center hole and the other corresponds to the center hole of the cam. For the convenience of expression, the positioning column 11 corresponding to the center hole is defined as positioning column A, and the positioning column 11 corresponding to the center hole of the cam is defined as positioning column B. The processing hole 12 corresponds to the hole to be processed on the brake base plate. At the same time, the width of the positioning mainboard 1 is smaller than the diameter of the brake base plate, so as not to block the brake base plate in a specific area and avoid affecting the processing of the brake base plate.

[0020] The clamping structure 3 includes a clamping plate 31 and a fastening stud 32. One end of the fastening stud 32 is fixedly connected to the positioning column A. The axes of the fastening stud 32 and the positioning column A coincide with each other. A nut 321 is provided at the other end of the fastening stud 32. The fastening stud 32 is provided with a thread matching the nut 321. The diameter of the nut 321 is larger than the diameter of the fastening stud 32. The clamping plate 31 is an approximately rectangular plate, and a through hole 311 is provided on the clamping plate 31. The through hole 311 is located in the center of the clamping plate 31 and passes through the clamping plate 31. The through hole 311 includes a mounting through hole 3111 and a fastening through hole 3112. The diameter of the mounting through hole 3111 corresponds to that of the nut 321. The diameter of the fastening through hole 3112 corresponds to that of the fastening stud 32. The mounting through hole 3111 is connected to the fastening through hole 3112. The clamping plate 31 is further provided with a limiting boss 312 , which is respectively provided at both ends of the clamping plate 31 and protrudes from the surface of the clamping plate 31 . The limiting boss 312 corresponds to the brake base plate so as to fit with the brake base plate.

[0021] The displacement device 2 includes a flipping device 21 and a translation device 22. The flipping device 21 includes a flipping motor 211 and a base 212. The end of the positioning mainboard 1 is rotatably connected to the base 212. Specifically, a rotating shaft can be installed at the end of the positioning mainboard 1 and connected to the base 212 to meet the rotation requirements of the positioning mainboard 1. The flipping motor 211 is connected to one side of the base 212. The output end of the flipping motor 211 is connected to the positioning mainboard 1 to drive the positioning mainboard 1 to rotate. The translation device 22 includes slider rails 221. There are two slider rails 221. The slider rails 221 are connected to each other, that is, the track of one slider rail 221 is mounted on the slider of the other slider rail 221. At the same time, the two slider rails 221 are arranged crosswise. Preferably, the angle between the two slider rails 221 is 90°. On the other hand, the slider of one slider rail is connected to the base 212 of the flipping device 21.

[0022] In actual use, the nut 321 is pre-assembled on the fastening stud 32. Hold the brake base plate and align the center hole on the brake base plate and the center hole of the cam with the positioning column A and positioning column B respectively. Push the brake base plate. At this time, because the diameter of the center hole is large enough, the nut 321 and the fastening stud 32 can pass through the center hole and penetrate the brake base plate. Continue to push the brake base plate so that the positioning column A is embedded in the center hole and the positioning column B is embedded in the center hole of the cam. In this way, the pre-connection of the brake base plate and the positioning main plate 1 is completed, so that the processed hole 12 on the positioning main plate 1 corresponds to the hole position to be processed on the brake base plate.

[0023] After the pre-connection is completed, hold the clamping plate 31. Align the mounting through-hole 3111 on the clamping plate 31 with the nut 321, and push the clamping plate 31. Because the diameter of the mounting through-hole 3111 matches that of the nut 321, and the diameter of the nut 321 is larger than that of the fastening stud 32, the nut 321 and the fastening stud 32 can pass through the mounting through-hole 3111 and pass through the clamping plate 31. When the clamping plate 31 is in contact with the brake base plate, the nut 321 and the positioning main plate 1 are respectively located on both sides of the clamping plate 31. At this time, translate the clamping plate 31 so that the fastening stud 32 can pass through the connection between the mounting through-hole 3111 and the fastening through-hole 3112 and enter the fastening through-hole 3112. Because the diameter of the fastening through-hole 3112 matches the diameter of the fastening stud 32 and is smaller than the diameter of the nut 321, the nut 321 can be rotated so that the nut 321 contacts the clamping plate 31. The nut 321 is continuously rotated until the nut 321 is tightened on the clamping plate 31. At this point, the nut 321 and the positioning main plate 1 clamp the brake base plate.

[0024] On the other hand, because the limiting boss 312 protrudes from the surface of the clamping plate 31, during the tightening of the nut 321, the limiting boss 312 fully engages the brake base plate, while the clamping plate 31 does not engage the positioning column A. This effectively reduces the relative position error between the brake base plate and the positioning base plate 1 by cooperating with the positioning base plate 1. The brake base plate is thus positioned.

[0025] Once the brake base plate is positioned, the positioning main plate 1 can be rotated by the flip motor 211 as needed, thereby rotating the brake base plate. Alternatively, the flip device 21 can be translated by the two slider rails 221 as needed, thereby driving the brake base plate to translate via the positioning main plate 1. Thus, the relative position between the brake base plate and the drilling equipment can be adjusted via the displacement device 2 to meet the requirements of different hole positions, different processing depths, and different processing angles. In summary, the present invention eliminates the need to replace other positioning tooling during the brake base plate machining process, greatly facilitating actual operation.

[0026] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
