A plurality of small folding plates are also formed in the middle of the bottom plate 6. A plurality of punching holes 61 are formed on the small folding plates, the bottom surface of the bottom plate and each side plate. At the same time, there are a plurality of card blocks 62 formed by stamping on each side plate.

This type of inspection is difficult to meet the requirements of shortening the construction time of large inspection fixtures. In addition, these tools also have accuracy problems. Some measuring tools may be difficult to achieve the required high-precision requirements, especially in the dimensional measurement of large parts. Finally, for the measurement of some large base plate parts, it may be necessary to transport the base plate from the production site to the measuring equipment, which is not only time-consuming but also may affect the measurement efficiency.

[0014] A positioning pin and a positioning block, wherein the positioning pin is adapted to cooperate with the first positioning hole, and the positioning block is adapted to cooperate with the second positioning hole;

[0015] When the positioning pin passes through the circular punching hole on the bottom plate and is inserted into the first positioning hole, and the positioning block passes through the rectangular punching hole on the bottom plate and is inserted into the second positioning hole, the bottom plate is at the reference position of the base.

[0016] Furthermore, a positioning sleeve is provided in the first positioning hole;

[0046] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] The present application provides a base plate size detection fixture, which is described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0048] In order to solve the technical problem of low detection efficiency in the prior art of base plate size detection relying on manual detection with measuring tools, an embodiment of the present application provides a base plate size detection fixture, which is described in detail below.

[0049] like Figure 1 The bottom plate 6 shown in the figure has a plurality of punching holes 61 formed on the bottom plate 6. The punching holes 61 are in the shape of circular holes and rectangular holes. The punching holes 61 are distributed on the bottom surface of the bottom plate 6 and each side plate. At the same time, a card block 62 is formed on the side plate. The card block 62 is circular or rectangular. The circular card block 62 is formed by stamping to form a protruding card block 62. The circular card block 62 is perpendicular to the side plate. The rectangular card block 62 is directly cut on the side plate, and the rectangular card block is located above the side plate.

[0050] like Figures 2 to 9 As shown, a base plate size detection fixture includes

[0051] A base 1, wherein four equal-height cushion columns 11 are arranged on the base 1, and the bottom plate 6 to be tested is suitable for being placed on the equal-height cushion columns 11;

[0052] A positioning mechanism, which is arranged on the base 1, and is suitable for cooperating with the circular punching hole 61 and the rectangular punching hole 61 on the bottom plate 6, so as to position the bottom plate 6 to be tested to a reference position;

[0053] Four quick clamps 12 are arranged on the base 1, and the quick clamps 12 are suitable for vertically clamping the bottom plate 6 to be tested on each of the equal-height cushion columns 11;

[0054] In this embodiment, the position where the quick clamp 12 clamps the base plate 6 is just above the equal-height cushion columns 11 , that is, the base plate 6 has four clamping positions and is clamped between the equal-height cushion columns 11 and the clamping blocks of the quick clamp 12 .

[0055] A plurality of measuring tool seats 2 are fixedly arranged on the base 1, and a first measuring tool 31 and / or a second measuring tool 32 and / or a third measuring tool 33 and / or a fourth measuring tool 34 are arranged on the measuring tool seat 2. The first measuring tool 31 is suitable for detecting the size of the punching hole 61, the second measuring tool 32 is suitable for detecting the position of the block 62, the third measuring tool 33 is suitable for detecting the verticality of the side plate, and the fourth measuring tool 34 is suitable for detecting the position of the side plate.

[0056] Specifically, a single measuring tool seat 2 can only be equipped with one measuring tool, or multiple measuring tools can be installed at the same time. The specific number of measuring tools to be installed is determined by technical personnel in this field based on the actual installation space on the base 1, the cost, and the size of the measuring tool seat 2.

[0057] In this embodiment, four supporting legs 13 are arranged below the base 1. The supporting legs 13 can be freely adjusted in height.

[0058] To facilitate carrying the clamp, handles may be provided on both sides of the base 1 .

[0059] In this embodiment, the first measuring tool 31 includes

[0060] A slide column, the slide column passes through the measuring tool seat 2;

[0061] A gauge member 311, which is arranged at the front end of the sliding column;

[0062] The slide column drives the gauge member 311 to cooperate with the punching hole 61 on the side plate to detect whether the size, position and size of the punching hole 61 are qualified.

[0063] When the slide column moves horizontally on the base 1, each punching hole 61 on the side plate can be detected. The slide seat can also be directly installed on the base 1, such as Figure 6 As shown, the slide column moves vertically up and down on the base 1, and at this time the slide column detects each punching hole 61 on the bottom surface of the bottom plate 6.

[0064] like Fig. 9As shown, in order to facilitate the reset of the slide post, the slide post is sleeved with a reset spring 312, the front end of the reset spring 312 abuts against the gauge seat 2, and the rear end abuts against the slide post, so that the slide post is in a rear position when static. The operator presses the slide post to drive the slide post and the gauge 311 to move forward, and automatically resets backward after releasing.

[0065] In this embodiment, the second measuring tool 32 includes a measuring block, which is slidably arranged in the measuring tool seat 2, and a measuring groove is provided at the front end of the measuring block.

[0066] The second measuring tool 32 is used to detect the position and size of the block 62. Therefore, the shape of the measuring groove is adjusted according to the shape of the block 62. When measuring the circular block 62, the measuring groove is a cylindrical slot hole, and when measuring the rectangular block 62, the measuring groove is a rectangular notch.

[0067] In order to facilitate the movement of the measuring block in the measuring tool seat 2, a hexagon socket screw is connected to the measuring block, and the measuring block can be conveniently driven to move by the hexagon socket screw.

[0068] The principle structure of the third gauge 33 and the fourth gauge 34 is the same as that of the second gauge 32, and the detection is also performed by moving a measuring block back and forth. The third gauge 33 is used to detect the verticality of the side plate, and the fourth gauge 34 detects the position of the side plate. The so-called verticality refers to the side plate relative to the bottom plane. Therefore, the measuring block in the third gauge 33 needs to refer to the bottom plane when it is installed in the gauge seat 2. The so-called position refers to the position of the side plate relative to the reference hole, that is, it mainly detects whether the position of the side plate bent on the bottom plate 6 is qualified. Therefore, the installation position of the measuring block in the fourth gauge 34 in the gauge seat 2 refers to the reference hole on the base 1.

[0069] In this embodiment, the fourth measuring tool 34 and the third measuring tool 33 share the same measuring tool base 2 .

[0070] In this embodiment, the verticality and position of the front side plate 6-1, the left side plate 6-3 and the right side plate 6-4 are mainly detected, and the rear side plate 6-2 is not detected. Figure 5 , no measuring tool is provided for testing the rear side plate 6-2.

[0071] like Figure 2 Figure 3 As shown, the positioning mechanism includes

[0072] The first pin hole and the second pin hole are both provided on the base;

[0073] A first positioning pin 51 and a second positioning pin 52, the two positioning pins are respectively matched with the two pin holes;

[0074] When the first positioning pin 51 and the second positioning pin 52 respectively pass through the first positioning hole 61 - 1 and the second positioning hole 61 - 2 on the bottom plate 6 and are respectively inserted into the first pin hole and the second pin hole on the base 1 , the bottom plate 6 is at the reference position of the base 1 .

[0075] In this embodiment, a positioning sleeve 5-1 is disposed in each of the first pin hole and the second pin hole;

[0076] The first pin hole and the second pin hole both include a cylindrical section and a conical section. The conical section cooperates with the punching hole 61 of the bottom plate 6, and the cylindrical section cooperates with the positioning sleeve 5-1.

[0077] The main function of the positioning mechanism is to install the base plate 6 to the measurement reference position of the base 1. The first positioning hole 61-1 and the second positioning hole 61-2 are reference holes. The installation position of the fourth measuring tool 34 can be installed based on the first positioning hole 61-1.

[0078] like Figure 4 As shown, a rectangular through hole is provided on the base, and the rectangular through hole cooperates with a rectangular block 53. The rectangular block 53 is used to detect the rectangular punching hole on the base plate. After the base plate is positioned at the reference position, the rectangular block 53 is inserted into the rectangular punching hole. If the rectangular block 53 can be inserted into the rectangular through hole of the base, it is qualified, otherwise it is unqualified.

[0079] In the base plate size detection fixture of the utility model, the left side, right side and front side of the base 1 are mainly distributed with the first measuring tool 31 and the second measuring tool 32. The first measuring tool 31 and the second measuring tool 32 are installed according to the punching holes 61 and the convex positions on the actual base plate 6. The first measuring tool 31 and the second measuring tool 32 can also share a measuring tool seat 2.

[0080] The third measuring tool 33 and the fourth measuring tool 34 are distributed at the four end corners of the base 1, and are mainly used to detect the position and verticality of the front side, the left side plate 6-3 and the right side plate 6-4.

[0081] like Figure 7 As shown, the third measuring tool 33 and the fourth measuring tool 34 share a measuring tool seat 2, and the fourth measuring tool 34 is located below the third measuring tool 33. The third measuring tool 33 and the fourth measuring tool 34 have the same moving direction, both of which move in the length direction of the opposite side and are respectively connected with the end of the side plate, so as to judge whether the verticality and position of the side plate are qualified.

[0082] The method of using the base plate size detection fixture is as follows:

[0083] like Figures 5 to 9 As shown, the bottom plate 6 is placed on four equal-height cushion columns 11 of the base 1, and then the positioning pins 51 and the positioning blocks 52 are inserted in sequence to ensure that the bottom plate 6 is in the reference position of the base 1;

[0084] After the bottom plate 6 is installed, the operator can sequentially operate each first measuring tool 31 to detect the position of each punching hole 61 on the bottom plate 6, operate each second measuring tool 32 to detect the position of the block 62 on the bottom plate 6, operate each third measuring tool 33 to detect the verticality of each side plate, and operate each fourth measuring tool 34 to detect the position of the side plate.
