Description

Technical Field

[0001] This utility model relates to a fitter's measuring tool for artillery brackets, belonging to the field of mechanical technology. Background Technology

[0002] In machining, fitters are an indispensable part of the process. Generally speaking, machining problems that are unsuitable or unsolvable by mechanical methods are handled by fitters. The bracket is an important component of artillery, and the sealing body is welded to the inside of the left and right support arms of the bracket. After welding, local deformation occurs, causing dimensional deviations. Due to its location, it cannot be machined on a machine tool. Therefore, the fitter grinds the workpiece to complete the machining. However, general measuring tools cannot accurately measure the dimensions of the sealing body. A special measuring tool is needed to help the fitter measure the dimensional deviations and then carry out the subsequent grinding work. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a fitter's measuring tool for artillery brackets. This tool can solve the problem that fitters cannot accurately locate the grinding part during the grinding of the sealing body, and reduce a lot of work when grinding is performed again during subsequent assembly.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a fitter's measuring tool for artillery brackets, including a mandrel, measuring rod, cylindrical pin, column and sleeve. The mandrel is a separate workpiece, including a handle a, a rear baffle, a shaft, a front baffle and a bushing. The handle a is U-shaped, and the opening of the handle a is fixedly connected to one side of the rear baffle. The other side of the rear baffle is fixedly connected to one end of the shaft, and a front baffle is installed inside the other end of the shaft. There are two bushings, which can fit through the shaft. One bushing is located on the shaft near the rear baffle, and the other bushing is located on the shaft away from the rear baffle.

[0005] A column is fixedly connected to one side of the sleeve in the circumferential direction. One end of the measuring rod is installed in the column, and the other end of the measuring rod is connected to a cylindrical pin. The shaft of the mandrel can pass through the sleeve.

[0006] Furthermore, the measuring rod is made of W6Mo5Cr4V2 material, and a handle b is installed on the measuring rod between the column and the cylindrical pin.

[0007] Furthermore, the shaft is a long cylindrical workpiece.

[0008] Furthermore, the measuring rod and the cylindrical pin are arranged perpendicularly.

[0009] Furthermore, the column and the sleeve together form a positioning sleeve.

[0010] Furthermore, a central hole is provided on the front baffle.

[0011] The beneficial effects of this utility model are as follows: This utility model utilizes high-precision hole positioning after the workpiece itself is machined, cleverly employing workpiece positioning to measure the relative positional dimensions of various components, thus reducing the requirements for the flatness grade of the large-area platform for fitters; the use of a bushing design makes this measuring tool applicable to brackets with different shaft holes, requiring only the bushing to be changed when using different brackets; it can also achieve the measurement purpose by changing the measuring rod according to the different dimensions of the sealing body, improving the versatility of this measuring tool; both the measuring tool and the mandrel are equipped with handles for convenient use by fitters; this measuring tool solves the problem of inconvenient measurement of the internal sealing body of the bracket, and by using the measuring tool to simulate the fit and correct interference points, it moves the work that would otherwise need to be done during final assembly, adjustment, and grinding forward, reducing the workload of final assembly, lowering labor intensity, and improving production efficiency.

[0021] like Figure 1As shown in Figure 6, a fitter's measuring tool for an artillery bracket includes a mandrel 1, a measuring rod 2, a cylindrical pin 4, a column 5, and a sleeve 6. The mandrel 1 is a separate workpiece and includes a handle a101, a rear baffle 102, a shaft 103, a front baffle 104, and bushings 105. The handle a101 is U-shaped and its opening is fixedly connected to one side of the rear baffle 102. The other side of the rear baffle 102 is fixedly connected to one end of the shaft 103. The shaft 103 is a long cylindrical workpiece, and a front baffle 104 is installed inside the other end of the shaft 103. The front baffle 104 has a central hole. There are two bushings 105, which can fit through the shaft 103. One bushing 105 is located on the shaft 103 near the rear baffle 102, and the other bushing 105 is located on the shaft 103 away from the rear baffle 102.

[0022] A column 5 is fixedly connected to one side of the sleeve 6 in the circumferential direction. The column 5 and the sleeve 6 form a positioning sleeve. One end of the measuring rod 2 is installed in the column 5, and the other end of the measuring rod 2 is connected to a cylindrical pin 4. The measuring rod 2 and the cylindrical pin 4 are arranged perpendicularly. The measuring rod 2 is made of W6Mo5Cr4V2 material. A handle b3 is installed on the measuring rod 2 between the column 5 and the cylindrical pin 4. The shaft 103 of the mandrel 1 can pass through the sleeve 6.

[0023] The front baffle 104 has a central hole drilled in it to facilitate clamping and positioning when machining the outer diameter of the shaft. The handle a101 is welded to the outside of the rear baffle 102 to facilitate use by the operator. The bushing 105 is used to support the shaft 103. During use, it can reduce the friction between the shaft 103 and the workpiece. The bushing 105 can be replaced according to the shaft hole size of different products. By simply changing the outer diameter of the bushing 105, this mandrel 1 can be applied to different products, which greatly increases the applicability of the mandrel 1.

[0024] The positioning sleeve is welded from the sleeve 6 and the column 5. The sleeve 6 is made of 45 steel and is heat-treated to ensure a material hardness of HRC50-55. The inner hole of the sleeve 6 is clearance-fitted with the mandrel 1 to ensure that the positioning sleeve can move axially on the mandrel 1 to measure the sealing bodies 7 on the left and right sides. The measuring rod 2 is made of W6Mo5Cr4V2 and is heat-treated, preheated once and twice, heated, kept warm, and oil-cooled to ensure a material hardness of HRC60-62 and reduce wear during use. The cylindrical pin 4 adopts the standard part GB / T119.1-2000 and is connected to the measuring rod 2 with a clearance fit. During the use of the measuring instrument, the position and size of the sealing body 7 are judged by the sticking of the cylindrical pin 4. The handle b3 is threaded to the measuring rod 2 to facilitate the operation of the measuring instrument and the observation of the measurement during use.

[0025] The mandrel 1 is connected to the shaft hole of the bracket 8 through the bushing 105. The measuring tool rotates around the mandrel 1 through the positioning sleeve, and the measuring rod 2 is used to measure the dimensional deviation of the seal body 7. The mandrel 1 is used to align the center of the shaft hole, and the back baffle 102 is used for positioning. The handle a101 is welded to the back baffle 102 for easy use. The mandrel 1 can be used with bushings 105 of different outer diameters to fit shaft holes of different sizes. The sleeve 6 is welded to the column 5 and the measuring rod 2 is installed. The measuring rod 2 can be replaced to measure seal bodies 7 of different arc sizes. The measuring rod 2 is made of W6Mo5Cr4V2 material and is heat-treated to improve its wear resistance and reduce measurement deviation caused by wear during use.

[0026] In use, place the two bushings 105 into the left and right trunnion holes of the bracket 8 respectively. The mandrel 1 passes through the bushing 105 on one side, the sleeve 6 and the bushing 105 on the other side in sequence. When measuring, hold the handle b3 and rotate the sleeve 6 around the mandrel 1. The parts that the cylindrical pin 4 cannot pass through need to be ground. After checking one side of the seal 7, move the measuring tool along the mandrel 1 to the other side and measure the seal 7 in the same way. Grind the parts that do not meet the size.
