Description

Technical Field

[0001] This application relates to the field of process fixture technology, and specifically discloses a process fixture. Background Technology

[0002] Process gauges are specialized tools used for real-time inspection of parts during the production process. They are designed to ensure that the dimensional accuracy, shape, and position of products meet design requirements during processing and assembly. Our company offers one such product: a testing pin, as shown in the instruction manual. Figure 1 As shown, the rounded corners at both ends of the detection pin are inconsistent. One end has a rounded corner of R3, and the other end has a distance of 3.5mm from the reference surface. This product is quite special, so a special tool is needed to inspect this component. In view of this, the inventor proposes a process inspection fixture.

[0003] This invention provides a process inspection tool to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem of whether the chamfer position data of the detection pin is accurate.

[0005] To achieve the above objectives, this utility model provides the following basic solution:

[0006] A process gauge includes a base plate, a first connecting hole symmetrically arranged on the upper side of the base plate, a second connecting hole symmetrically arranged on the lower side of the base plate, a pin seat detachably connected to the first connecting hole, a positioning plate detachably connected to the second connecting hole, and a first distance sensor and a second distance sensor disposed inside the pin seat.

[0007] The first connecting hole and the second connecting hole are symmetrical about the central axis of the base plate, and the bisectors of the pin seat and the positioning plate coincide with the central axis of the base plate.

[0008] Furthermore, a slot is opened in the center of the pin holder, and a cover plate is fixed to the top of the slot. The detection end of the product is inserted into the slot, and after passing through the other end of the slot, it contacts one end of the positioning plate.

[0009] Furthermore, the first connecting hole includes a first through hole and a first pin hole arranged symmetrically, and the second connecting hole includes a second through hole and a second pin hole. The first through hole and the first pin hole are in two sets. The first through hole and the first pin hole located on the left side of the central axis of the base plate are arranged vertically, and the first through hole and the first pin hole located on the right side of the central axis of the plate are arranged vertically. The second through hole is symmetrical about the central axis of the base plate, and the second pin hole is symmetrical about the connecting line between the second through holes.

[0010] Furthermore, both the first pin hole and the second pin hole are connected to a first pin and a second pin, and the pin seat and the positioning plate are respectively connected to the base plate through the first pin and the second pin.

[0011] Furthermore, the inner diameter of the slot is equal to the outer diameter of the product before the corner is opened. When the other end of the product passes through and contacts one end of the positioning plate, the first distance sensor and the second distance sensor act on the outer diameter of the product after the corner is opened.

[0012] Furthermore, the second distance sensor is used to measure the accuracy of the right end face of the product, and the first distance sensor is used to measure the accuracy of the left end face of the product. The initial reference surfaces of both the first and second distance sensors are flush with the slot wall.

[0013] The principle and effect of this solution are as follows:

[0014] 1. Compared with existing technologies, this device has a simple structure and ingenious design. This device is a process inspection tool for a specific product, which can realize the insertion inspection of the product's appearance dimensions and opening angle dimensions. The insertion inspection is used to determine whether the product meets the qualified standards. This device solves the problem of detecting the chamfer position data of the pin and whether the appearance dimensions are accurate. Attached Figure Description

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] The reference numerals in the accompanying drawings include: detection pin 1, left detection point 2, right detection point 3, base plate 4, positioning plate 5, contact surface 6, second pin 7, second connecting hole 8, pin seat 9, first pin hole 10, second distance sensor 11, first distance sensor 12, first connecting hole 13, first pin hole 14, and second pin hole 15.

[0022] Implementation, for example Figure 1 As shown: Figure 1 The product to be tested in this application is a type of pin, specifically one type of pin 1. This pin is characterized by having different opening angle requirements at its end fillet positions, such as... Figure 1 As shown, the left end of the detection pin 1 is R3, i.e., the left detection point 2, and the right end of the detection pin 1 is 3.5mm, i.e., the right detection point 3. Based on this product, this application provides a process inspection fixture specifically for this product, as follows:

[0023] A process inspection fixture includes a base plate 4, a first connecting hole 13 symmetrically arranged on the upper side of the base plate 4, a second connecting hole 8 symmetrically arranged on the lower side of the base plate 4, a pin seat 9 detachably connected to the first connecting hole 13, a positioning plate 5 detachably connected to the second connecting hole 8, and a first distance sensor 12 and a second distance sensor 11 disposed inside the pin seat 9.

[0024] The first connecting hole 13 and the second connecting hole 8 are symmetrical about the central axis of the base plate 4, and the bisectors of the pin seat 9 and the positioning plate 5 coincide with the central axis of the base plate 4.

[0025] Specifically: A slot is formed in the center of the pin holder 9, and a cover plate is fixed to the top of the slot. The detection end of the product is inserted into the slot, and after passing through the other end of the slot, it contacts one end of the positioning plate 5. The positioning plate 5 has a contact surface 6, which contacts the detection pin 1. Figure 3As shown: the first connecting hole 13 includes a first through hole and a first pin hole 10 symmetrically arranged, and the second connecting hole 8 includes a second through hole and a second pin hole 15. The first through hole and the first pin hole 10 are both in two sets. The first through hole and the first pin hole 10 located on the left side of the central axis of the base plate 4 are arranged vertically, and the first through hole and the first pin hole 10 located on the right side of the central axis of the plate are arranged vertically. The second through hole is symmetrical about the central axis of the base plate 4, and the second pin hole 15 is symmetrical about the connecting line between the second through holes. The first pin hole 10 and the second pin hole 15 are each connected to a first pin and a second pin 7. The pin seat 9 and the positioning plate 5 are respectively connected to the base plate 4 through the first pin and the second pin 7.

[0026] The pin seat 9 and the positioning plate 5 are installed through the first connecting hole 13 and the second through hole, so that the center line of the pin seat 9 and the positioning plate 5 coincides with the center line of the base plate 4.

[0027] Regarding the arrangement of the slots: the inner diameter of the slot is equal to the outer diameter of the product before the corners are opened. After the other end of the product passes through and contacts one end of the positioning plate 5, the first distance sensor 12 and the second distance sensor 11 act on the outer diameter of the product after the corners are opened. The second distance sensor 11 is used to measure the right end face of the product accurately, and the first distance sensor 12 is used to measure the left end face of the product accurately. The initial reference surfaces of the first distance sensor 12 and the second distance sensor 11 are both flush with the slot wall.

[0028] The reason why the other end of the product needs to protrude and contact one end of the positioning plate 5 is to fix the product as a whole, fixing the relative distance between the product and the slot after insertion. The overall external dimensions of the product are determined by the inner diameter of the slot. The left detection point 2, R3 on the left side of the detection pin 1, is determined by the first distance sensor 12. The right detection point 3, 3.5mm on the right side of the detection pin, is determined by the second distance sensor 11. The first distance sensor 12 and the second distance sensor 11 are connected to a power supply through wires to enable the normal operation of the first distance sensor 12 and the second distance sensor 11. The wires should run through the base plate 4 without affecting the insertion of the detection pin 1. The first distance sensor 12 and the second distance sensor 11 are electrically connected to a computer, which is used for data analysis to determine whether the left and right sides of the detection pin 1 are qualified.

[0029] This device solves the problem of whether the chamfer position data of the pin 1 is accurate. The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Although this utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the utility model's technical solution. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model without departing from the scope of the utility model's technical solution shall still fall within the scope of the utility model's technical solution.
