Description

Technical Field

[0001] This utility model belongs to the technical field of positioning clamp processing tooling, specifically relating to a tooling for processing a fixed base for a positioning clamp mounting bracket angle adjustment device. Background Technology

[0002] Chinese patent CN202411154199.3 discloses an angle adjustment device for a positioning clamp mounting bracket, including an adjustment base, an insulator pin, an insulator, and a positioning clamp mounting bracket. The adjustment base includes a fixed base and a fixed pin seat. The fixed base includes a fixed base plate and various machining holes are provided on the fixed base. The fixed base is machined from a fixed base profile, which can greatly improve production efficiency and reduce production costs.

[0003] However, the fixed base profile will undergo bending deformation during processing. Due to the large area of ​​the fixed base plate, the amount of deformation will be even greater, causing the fixed base plate to bend. To ensure the accuracy of the relative positions between the various machined holes of the fixed base, the bottom surface of the fixed base plate is usually machined first to achieve a certain degree of flatness. Then, using the flat bottom surface of the fixed base plate as a reference, the various holes on the fixed base are machined. However, this increases the workload and production cost of the fixed base plate, and also reduces the overall strength of the fixed base plate. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0005] First aspect: A tooling for processing the fixed base of a positioning clamp mounting bracket angle adjustment device, comprising a T-shaped positioning post, a locking pressure plate, a locking screw, a T-shaped positioning post fastening screw, and a base plate.

[0006] The T-shaped positioning post has a T-shaped structure, including a T-shaped head and a T-shaped body. The side of the T-shaped head near the T-shaped body forms the front and rear positioning surfaces of the T-shaped head. The left and right sides of the T-shaped body form the left mating surface and the right mating surface of the T-shaped body fixing base. Several T-shaped positioning post mounting threaded holes are opened at the bottom of the T-shaped positioning post. A clearance hole is opened at the T-shaped body near the T-shaped head. A locking pressure plate insertion hole is opened in the middle of the T-shaped body (1.2). The locking pressure plate insertion hole passes through the T-shaped body. Several locking pressure plate screw holes are opened on the left side of the middle part of the T-shaped body. All locking pressure plate screw holes are through holes leading to the locking pressure plate insertion hole.

[0007] The base plate has a fastening screw hole in the middle that corresponds to the threaded hole of the T-shaped positioning post. The bottom of the T-shaped positioning post abuts against the upper surface of the base plate, and the T-shaped positioning post and the base plate are tightly and reliably connected by the T-shaped positioning post fastening screw.

[0008] The fixed base is made by processing the fixed base profile. The fixed base profile is fitted onto the T-shaped positioning post. The horizontal left and right machining reference surfaces of the fixed base are respectively mated with the left mating surface and the right mating surface of the T-shaped fixed base. The horizontal front and rear machining reference surfaces of the fixed base are close to the front and rear positioning surfaces of the T-shaped head. The bottom surface of the fixed base is close to the upper surface of the base plate.

[0009] The locking plate is inserted through the locking plate insertion hole, and the locking screw is screwed into the locking plate screw hole. The locking screw extends out of the locking plate screw hole until it enters the locking plate insertion hole and abuts against the locking plate. By adjusting the locking screw, the right side of the locking plate is made to abut tightly against the left surface of the fixed base to be processed.

[0010] Furthermore, the upper end of the T-shaped body is provided with a left guide slope for fixing the base and a right guide slope for fixing the base. The guide slope is designed to make it easier to install the fixing base profile.

[0011] Furthermore, the base plate has fastening screw holes, including T-shaped positioning post fastening screw through holes and corresponding T-shaped positioning post fastening screw head countersunk holes.

[0012] Furthermore, the clearance holes include a first T-shaped clearance hole and a second T-shaped clearance hole, which correspond to the left and right side locking holes on the fixing pin seat on the fixed base, respectively, and their diameters are all larger than the diameters of the left and right side locking holes on the fixing pin seat on the fixed base.

[0013] Furthermore, the clearance hole is an oblong or rectangular hole, and its area can cover all the corresponding locking holes on the fixed base. This design requires only one clearance hole to be machined, making the operation convenient. The clearance hole is also relatively large, facilitating the feed and retraction of the drill bit when drilling the fixed base.

[0014] The second aspect: The method for processing the fixed base using the above-mentioned tooling specifically includes the following steps:

[0015] S1 Tooling Assembly:

[0016] S1-1. Place the T-shaped positioning post on the base plate and tighten the screws of the T-shaped positioning post to make the T-shaped positioning post and the base plate form a tight and reliable connection.

[0017] S1-2. Insert the locking plate through the locking plate insertion hole, screw the locking screw into the locking plate screw hole, and pre-adjust.

[0018] S2 material cutting:

[0019] Cut the base profile according to the predetermined dimensions.

[0020] S3 Set:

[0021] S3-1. Mount the fixed base profile onto the T-shaped positioning post. The horizontal left and right machining reference surfaces of the fixed base are respectively mated with the left mating surface and the right mating surface of the T-shaped fixed base. The horizontal front and rear machining reference surfaces of the fixed base are close to the front and rear positioning surfaces of the T-shaped head. The bottom surface of the fixed base is close to the upper surface of the base plate.

[0022] S3-2. Adjust the locking screw, and its right side will push the locking plate to the right, so that the right side of the locking plate can reliably press against the left surface of the fixed base, thus forming a reliable positioning and fixation of the fixed base before processing.

[0023] S4 processing:

[0024] S4-1. Machining the mounting holes for the fixed base and the fastening holes for the fixed pins on the bottom surface of the fixed base;

[0025] S4-2. Through the clearance hole, process the locking holes on the left and right sides of the fixing pin seat on the side of the fixed base.

[0026] S5 Unloading:

[0027] Loosen the locking screws so that the right side of the locking plate is away from the left surface of the fixed base, and remove the finished fixed base from the tooling.

[0028] Furthermore, in the steps of the above method of use, S4-1 precedes S4-2; or S4-2 precedes S4-1.

[0029] The beneficial effects of this utility model are:

[0030] The tooling for processing the fixed base of the positioning clamp mounting bracket angle adjustment device described in this utility model uses the upper edge of the "fixed base left vertical plate slide groove and fixed base right vertical plate slide groove" with relatively stable dimensions in the fixed base profile as a reference to process each hole system. The fixed base profile undergoes slight bending deformation within the allowable range, thereby ensuring the relative position accuracy between each processed hole system of the fixed base and facilitating operation.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] The tooling for processing in this utility model is applied to the processing of the fixed base in the positioning clamp mounting bracket angle adjustment device disclosed in Chinese Patent CN202411154199.3.

[0044] Please see Figure 1-3 As described in the patent document, the fixed base is manufactured by processing a fixed base profile. Various hole systems need to be processed on the fixed base profile, including the left and right side locking holes of the fixed pin seat on the side of the fixed base, the fixed base mounting holes on the bottom surface of the fixed base, and the fixed pin seat fastening holes. Example 1:

[0045] Please see Figure 4 and 10 The tooling for machining the fixed base of the positioning clamp mounting bracket angle adjustment device includes a T-shaped positioning post 1, a locking pressure plate 2, a locking screw 3, a T-shaped positioning post fastening screw 4, and a base plate 5.

[0046] Please see Figure 5-7 The T-shaped positioning post 1 has a T-shaped structure, including a T-shaped head 1.1 and a T-shaped body 1.2. The cross-sectional shape and size of the T-shaped positioning post 1 are adapted to the cross-sectional shape and size of the fixed base profile. The T-shaped head 1.1 forms a front and rear positioning surface 1.3 on the side near the T-shaped body 1.2. The left and right sides of the T-shaped body 1.2 form a left mating surface 1.4 and a right mating surface 1.5 of the T-shaped body fixed base. The bottom of the T-shaped positioning post 1 has several T-shaped positioning post mounting threaded holes 1.6.

[0047] Please see Figure 2 and 6 In this embodiment, two clearance holes are provided. The T-shaped body 1.2 is provided with a first T-shaped body machining clearance hole 1.7 and a second T-shaped body machining clearance hole 1.8 near the T-shaped head 1.1. The first T-shaped body machining clearance hole 1.7 and the second T-shaped body machining clearance hole 1.8 correspond to the left and right side locking holes on the fixing pin seat on the fixed base, respectively, including corresponding positions and the same shape. The diameters of the first T-shaped body machining clearance hole 1.7 and the second T-shaped body machining clearance hole 1.8 are both larger than the diameters of the left and right side locking holes on the fixing pin seat on the fixed base.

[0048] In other embodiments, the first T-shaped body is machined to avoid the hole 1.7 and the second T-shaped body is machined to avoid the hole 1.8 and they are connected to form an integral waist-shaped hole or rectangular hole. The avoidance hole is designed as a waist-shaped hole or a rectangular hole to facilitate the entry and exit of the tool during drilling.

[0049] Please see Figure 6 A locking plate insertion hole 1.9 is provided in the middle of the T-shaped body 1.2. The locking plate insertion hole 1.9 passes through the T-shaped body 1.2. Several locking plate screw holes 1.10 are provided on the left side of the middle part of the T-shaped body 1.2. All locking plate screw holes 1.10 are through holes leading to the locking plate insertion hole 1.9.

[0050] Please see Figure 7 The upper end of the T-shaped body 1.2 is provided with a left guide slope 1.11 for fixing the base and a right guide slope 1.12 for fixing the base. The guide slope is designed to facilitate the installation of the fixing base profile.

[0051] Please see Figure 4 and 8-10, the middle part of the base plate 5 is provided with several T-shaped positioning post fastening screw through holes 5.1 and corresponding T-shaped positioning post fastening screw head countersunk holes 5.2, and the T-shaped positioning post fastening screw through holes 5.1 and T-shaped positioning post fastening screw head countersunk holes 5.2 are arranged coaxially.

[0052] The bottom of the T-shaped positioning post 1, that is, the side with several T-shaped positioning post mounting threaded holes 1.6, abuts against the upper surface of the base plate 5, and the T-shaped positioning post 1 and the base plate 5 are tightly and reliably connected by the threaded connection between the T-shaped positioning post fastening screw 4 and the T-shaped positioning post fastening screw through hole 5.1.

[0053] The fixed base 6 is manufactured by processing a fixed base profile. The fixed base profile is fitted onto the T-shaped positioning post 1. The horizontal left and right processing reference surfaces of the fixed base 6 are respectively fitted with the left mating surface 1.4 and the right mating surface 1.5 of the T-shaped fixed base. The horizontal front and rear processing reference surfaces of the fixed base 6 are close to the front and rear positioning surfaces 1.3 of the T-shaped head. The bottom surface of the fixed base 6 is close to the upper surface of the base plate 5.

[0054] Please see Figure 4 , 6 10. The locking plate 2 is inserted through the locking plate insertion hole 1.9, and the locking screw 3 is screwed into the locking plate screw hole 1.10. The locking screw 3 extends out of the locking plate screw hole 1.10 until it enters the locking plate insertion hole 1.9 and abuts against the locking plate 2. The locking screw 3 is adjusted with a screwdriver so that the right side of the locking plate 2 is in close contact with the left surface of the fixed base 6 to be processed.

[0055] In other embodiments, a screw with a handle is used instead of the locking screw 3. The handle of the screw is located outside the screw hole 1.10 of the locking plate, so there is no need to use a screwdriver to adjust it. It is more convenient to adjust the locking screw by hand. The screw with the handle is not shown in the figure.

[0056] The aforementioned tooling uses the upper edges of the relatively stable dimensions of the "left vertical plate slide groove and right vertical plate slide groove of the fixed base" in the fixed base profile as a reference to process each hole system. The bending deformation of the fixed base profile is within the allowable range, thereby ensuring the relative position accuracy between the various machined hole systems of the fixed base. Example 2:

[0057] The specific operating steps for using the tooling described in Embodiment 1 are as follows:

[0058] S1 Tooling Assembly:

The horizontal front and rear machining reference surfaces of the fixed base 6 are close to the front and rear positioning surfaces 1.3 of the T-shaped head. The bottom surface of the fixed base 6 is close to the upper surface of the base plate 5.

[0065] S3-2 Adjust the locking screw 3, and its right side pushes the locking plate 2 to the right, so that the right side of the locking plate 2 reliably presses against the left surface of the fixed base 6, forming a reliable positioning and fixation of the fixed base 6 before processing.

The bending deformation of the fixed base profile is within the allowable range, thereby ensuring the relative position accuracy between each processed hole system of the fixed base.

[0073] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
