Description

Technical Field

[0001] The utility model relates to the technical field of detection auxiliary equipment for silicone seals, and more particularly to a silicone piece measuring jig. Background Art

[0002] Sleeve-type silicone parts are a commonly used sealing component, such as Cable Grommet (cable protection rubber ring). Since this type of product is made of silicone material, which is a special material and has a low hardness, the product cannot be shaped during measurement, and conventional measurement methods cannot accurately obtain the size.

[0003] Furthermore, inspecting the product's appearance is notoriously difficult. For example, due to the product's low hardness, it may collapse or become soft, making it difficult to detect defects. Some products lack distinguishing features, so some parts may be inspected repeatedly, and some parts may be missed.

[0004] In order to meet users' needs for accurate measurement and appearance inspection, a special auxiliary fixture needs to be set up for this type of product. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a silicone part measuring jig, which can keep the product to be tested stable, accurately measure the product size, and more comprehensively inspect the product appearance, thereby improving detection efficiency and accuracy.

[0006] According to one aspect of the present invention, a silicone part measuring jig is provided, which is an auxiliary jig for measuring sleeve-type silicone parts. The silicone part measuring jig includes a base and a rotating shaft. The base has a bottom plate and vertically upward side plates on both sides of the bottom plate. The top of the side plate is provided with an open accommodating groove, and the bottom of the accommodating groove is semicircular arc-shaped. Both ends of the rotating shaft have cylindrical shaft ends, and the outer walls of the shaft ends are adapted to the bottom of the accommodating groove. The rotating shaft is used to put the sleeve-type silicone part to be measured. The shaft ends at both ends of the rotating shaft can be rotatably placed in the accommodating groove. The rotating silicone part rotates with the shaft end as the center, and the silicone part rotates synchronously with the rotating shaft. Therefore, the silicone product to be tested is inserted from one end of the rotating shaft, the product is put on the rotating shaft, the rotating shaft supports the inner wall of the product, the product can be firmly attached to the surface of the rotating shaft, and the end of the shaft is placed in the receiving groove of the base for positioning. At this time, the product can be measured, such as length measurement; during the measurement process, the fixture can ensure that the silicone product remains stable to avoid affecting the accuracy of the measurement due to movement or deformation; when it is necessary to inspect the appearance of the silicone product, the silicone product can be rotated, and the rotating shaft rotates with the silicone product. The inspector can carefully inspect the appearance of the entire product. If there is any defect, it can be discovered quickly.

[0007] In some embodiments, the outer diameter of the rotating shaft gradually increases from left to right, and an insertion direction indicator is engraved on the outer circumference of the rotating shaft, pointing from the left end to the right end. Therefore, the silicone product targeted by this application has a tapered inner wall. When the product is inserted into the rotating shaft along the insertion direction indicator, the outer wall of the rotating shaft fits against the inner wall of the product, ensuring that the product remains stable and does not move or deform, thereby ensuring accurate and reliable measurement.

[0008] In some embodiments, the left end of the shaft is uniformly marked with four angle markings of 0 degrees, 90 degrees, 180 degrees, and 270 degrees along its circumference, with the 0 degree marking aligned with the insertion direction marking. Thus, the product is a sleeve-like structure, i.e., a structure that wraps around a circle. Some products have a smooth, unmarked appearance. During the appearance inspection, it is impossible to determine whether a full circle has been inspected, which may lead to missed inspections or duplicate inspections. When placing the shaft, we can place it horizontally at 0 and 180 degrees or 90 and 270 degrees. Inspectors can use the angle markings to determine whether the inspection is complete, thus avoiding missed inspections or duplicate inspections.

[0009] In some embodiments, the base is equipped with a plurality of rotating shafts of different sizes. The outer diameter of the shaft ends of each rotating shaft is the same and can be adapted to fit within the receiving groove. Therefore, due to the different sizes of products, a single base can be equipped with multiple rotating shafts, and the dimensions of the mounting points of the rotating shafts are consistent. This allows the base to be universally used, saving the cost of fixtures.

[0010] In some embodiments, the rotating shaft includes a rotating shaft body and at least one sleeve sleeved outside the rotating shaft body, with the shaft ends being located at both ends of the rotating shaft body. The outer diameter of the rotating shaft body gradually increases from left to right, and both the outer diameter and inner diameter of the sleeve gradually increase from left to right. The inner diameter of the sleeve matches the outer diameter of the rotating shaft body. Pin grooves are provided on the outer wall of the right end of the rotating shaft body and the inner wall of the right end of the sleeve. When the sleeve is sleeved on the rotating shaft body, the two pin grooves are positioned using pins. Therefore, to improve the versatility of the fixture and save costs, the rotating shaft is designed as a split body. If the outer diameter of the rotating shaft body meets the product size requirements, the product can be directly sleeved on the rotating shaft body for testing. If the outer diameter of the rotating shaft body is not sufficient to support the product, the sleeve can be sleeved on the rotating shaft body. After the pin grooves of the rotating shaft body and the sleeve are aligned and fixed with pins, the product can be sleeved on the sleeve.

[0011] In some embodiments, multiple sleeves are provided, and the right ends of the multiple sleeves are each provided with a pin groove. The pin grooves of each sleeve are provided on the inner wall or outer wall of the adjacent sleeve to achieve positioning between adjacent sleeves using pins. Thus, a rotating shaft body can be configured with multiple sleeves. For example, if a sleeve is already installed on the rotating shaft body and still cannot meet the usage requirements, another sleeve can be installed on the sleeve. The pin groove is provided on the outer wall of the first sleeve, and the pin groove is provided on the inner wall of the adjacent sleeve. The pin groove on the outer wall of the first sleeve is staggered with the pin groove on the inner wall of the sleeve. After the rotating shaft body and the first sleeve are positioned, the adjacent sleeve and the first sleeve are also positioned using the pin groove and pin.

[0012] In some embodiments, the shaft includes a shaft body and a sleeve sleeved around the shaft body, with shaft ends disposed at opposite ends of the shaft body. The shaft body has a cylindrical outer wall, the sleeve has an inner wall that mates with the outer wall of the shaft body, and the outer diameter of the sleeve gradually increases from left to right. The sleeves are available in multiple sizes, each with a different outer diameter. Thus, the shaft is designed as a split body, with the cylindrical outer wall of the shaft body and sleeves of varying outer diameters, to meet the testing requirements of products of varying specifications.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the silicone parts measuring jig provided by the present invention has a simple structure and strong practicality. The silicone parts product to be measured is put on the rotating shaft, and the rotating shaft fits the product perfectly, which can stably fix the silicone seal with lower hardness. During the measurement process, the jig can keep the product stable, avoid affecting the measurement accuracy due to movement or deformation, and can accurately measure the product size. The supported product is placed on the base, and the product can be rotated to conveniently check whether the product appearance is qualified. According to the angle mark, it can be known whether the inspection is complete, avoiding missed inspections or repeated inspections. Using this jig, the product appearance can be inspected more comprehensively, the size can be measured more accurately, and the inspection efficiency can be greatly improved.

[0021] The present invention will be further described below in conjunction with specific implementation methods.

[0022] like Figure 1 As shown, one embodiment of the present invention is a silicone measuring jig for assisting in measuring silicone sleeves. This application is primarily directed to a jig for Cable Grommet products, which are silicone products with a tapered inner wall.

[0023] Example 1

[0024] like Figures 1 to 3 As shown, the silicone part measuring jig includes a base 1 and a rotating shaft 2. The base 1 has a bottom plate 11 and vertically upward side plates 12 located on both sides of the bottom plate 11. The top of the side plates 12 is machined into an open-shaped receiving groove 121, and the bottom of the receiving groove 121 is semicircular. The rotating shaft 2 has cylindrical shaft ends 21 at both ends, and the outer wall of the shaft end 21 is adapted to fit the bottom of the receiving groove 121, so that the shaft end 21 can rotate within the receiving groove 121. The rotating shaft 2 is used to hold the sleeve-like silicone part to be measured. The shaft ends 21 at both ends of the rotating shaft 2 are placed in the receiving groove 121. The inspector rotates the silicone part, and the rotating shaft 2 rotates around the shaft end 21 as the center, and the silicone part and the rotating shaft 2 rotate synchronously. To match the inner wall of the product, in this embodiment, the outer diameter of the rotating shaft 2 gradually increases from left to right. If the inner wall of the product is a cylindrical structure, the outer periphery of the rotating shaft 2 adopts a corresponding cylindrical structure.

[0025] Insert the silicone product to be tested from one end of the rotating shaft 2. The product is placed on the rotating shaft 2. The rotating shaft 2 supports the inner wall of the product. The product can be firmly attached to the surface of the rotating shaft 2. Place the end 21 of the shaft into the receiving groove 121 of the base 1 for positioning. At this time, the product can be measured, such as length measurement. During the measurement process, the jig can ensure that the silicone product remains stable to avoid affecting the accuracy of the measurement due to movement or deformation. When it is necessary to inspect the appearance of the silicone product, the silicone product can be rotated. The rotating shaft 2 rotates with the silicone product. The inspector can carefully inspect the appearance of the entire product. If there are any defects, they can be discovered quickly.

[0026] like Figure 4As shown, an insertion direction mark 22 is engraved on the outer periphery of the rotating shaft 2, and the insertion direction mark 22 points from the left end to the right end. The product is inserted into the rotating shaft 2 along the insertion direction mark 22. The insertion direction mark 22 does not protrude from the surface of the rotating shaft 2 and will not affect the insertion of the product.

[0027] like Figure 4 As shown, the left shaft end 21 is evenly marked with four angle marks 23 of 0 degrees, 90 degrees, 180 degrees and 270 degrees along its circumference. The 0 degree mark is aligned with the insertion direction mark 22. The mark can be formed by laser engraving.

[0028] Since the product is a sleeve-like structure, that is, a structure that wraps around the product, some products have a smooth, unmarked appearance. Therefore, during the appearance inspection, it is impossible to know whether a full inspection has been completed, which may lead to missed inspections or repeated inspections. Using the jig provided in this application, when we place the shaft 2, we can place it horizontally at 0 degrees and 180 degrees or 90 degrees and 270 degrees. The inspector can know whether the inspection is complete based on the angle mark, avoiding missed inspections or repeated inspections.

[0029] Example 2

[0030] The main difference between this embodiment and Example 1 is that the base 1 is equipped with a plurality of rotating shafts 2 of different sizes. The outer diameter of the shaft end 21 of each rotating shaft 2 is the same, so that each rotating shaft 2 can be adapted to fit within the receiving groove 121 of the base 1. Due to the different sizes of products, a single base 1 can be equipped with multiple rotating shafts 2, and the dimensions of the mounting points of the rotating shafts 2 are consistent, making the base 1 universal and saving fixture costs.

[0031] Example 3

[0032] The main difference between this embodiment and embodiment 1 is that the structure of the rotating shaft 2 is different. Specifically, Figure 5 As shown, the rotating shaft 2 includes a rotating shaft body 201 and at least one sleeve shaft 202 sleeved outside the rotating shaft body 201 .

[0033] Shaft ends 21 are located at both ends of the shaft body 201. The outer diameter of the shaft body 201 gradually increases from left to right. Both the outer and inner diameters of the sleeve 202 gradually increase from left to right, with the inner diameter of the sleeve 202 matching the outer diameter of the shaft body 201. Pin slots 203 are defined on the outer wall of the right end of the shaft body 201 and the inner wall of the right end of the sleeve 202. When the sleeve 202 is fitted onto the shaft body 201, the pin slots 203 of the two pin slots 203 are aligned, and the two pin slots 203 are positioned using a pin 204.

[0034] If the outer diameter of the shaft body 201 meets the product's dimensional requirements, the product can be directly placed on the shaft body 201 for testing. If the outer diameter of the shaft body 201 is insufficient to support the product, the sleeve 202 can be placed on the shaft body 201. After the pin slots 203 of the shaft body 201 and sleeve 202 are aligned and secured with pins 204, the product can be placed on the sleeve 202. This improves the versatility of the jig and saves costs.

[0035] like Figure 6 As shown, in a specific application, multiple sleeve shafts 202 can be provided. The sleeve shafts 202 can be designed to be stacked according to their size specifications. A pin slot 203 is formed at the right end of each of the multiple sleeve shafts 202. The pin slots 203 of each sleeve shaft 202 are provided on the inner wall or outer wall of adjacent locations to achieve positioning between adjacent sleeve shafts 202 using pins 204. In this way, a rotating shaft body 201 can be configured with multiple sleeves 202. For example, if a sleeve 202 has been put on the rotating shaft body 201 and it still cannot meet the usage requirements, another sleeve 202 can be put on the sleeve 202. A pin groove 203 is set on the outer wall of the first sleeve 202, and a pin groove 203 is set on the inner wall of the adjacent sleeve 202. The pin groove 203 on the outer wall of the first sleeve 202 is staggered with the pin groove 203 on the inner wall of the sleeve 202. After the rotating shaft body 201 and the first sleeve 202 are positioned, the adjacent sleeve 202 and the first sleeve 202 are also positioned through the pin groove 203 and the pin 204.

[0036] Example 4

[0037] The main difference between this embodiment and embodiment 1 is that the structure of the rotating shaft 2 is different. Figure 7 As shown, the rotating shaft 2 includes a rotating shaft body 201 and a sleeve shaft 202 that is sleeved outside the rotating shaft body 201. The shaft ends 21 are provided at both ends of the rotating shaft body 201, and the outer wall of the rotating shaft body 201 is cylindrical. The inner wall of the sleeve shaft 202 is adapted to the outer wall of the rotating shaft body 201, and the outer diameter of the sleeve shaft 202 gradually increases from left to right. The sleeve shaft 202 is provided in multiple specifications, and the outer diameter of each sleeve shaft 202 is different. The rotating shaft 2 is designed as a split body, with the outer wall of the rotating shaft body 201 being cylindrical and equipped with sleeve shafts 202 of different outer diameters to meet the testing requirements of products of different specifications.

[0038] The silicone parts measuring jig provided by the utility model has a simple structure but strong practicality. The silicone parts product with lower hardness to be tested is put on the rotating shaft 2. The rotating shaft 2 fits perfectly with the product and can stably fix the silicone seal with lower hardness. During the measurement process, the jig can keep the product stable, avoid affecting the accuracy of the measurement due to movement or deformation, and can accurately measure the product size. The supported product is placed on the base 1, and the product can be rotated to conveniently check whether the product appearance is qualified. According to the angle mark, it can be known whether the inspection is complete, avoiding missed inspections or repeated inspections. Using this jig, the appearance of the product can be inspected more comprehensively, the size can be measured more accurately, and the inspection efficiency can be greatly improved.

[0039] The above are only some embodiments of the present invention. It should be pointed out that for ordinary technicians in this field, other variations and improvements can be made without departing from the creative concept of the present invention, and these all fall within the scope of protection of the present invention.
