Description

Technical Field

[0001] This utility model belongs to the field of auxiliary measurement tooling technology, specifically a movable tooling for assisting in the measurement of large products. Background Technology

[0002] When inspecting automotive hoods and door panels, the dimensional tolerances of large products such as automotive hoods and door panels are required to be high. Therefore, CMM is used for measurement. However, because automotive hoods and door panels occupy a large area, the manual operation mode of CMM will occupy a large measurement area when measuring them. In addition, they need to be moved to the worktable one by one. However, each time they are placed on the worktable, they need to be re-tested, which seriously increases the measurement intensity, reduces the measurement efficiency, and also reduces the measurement accuracy.

[0003] Meanwhile, the surfaces of large products such as automotive door panels or covers are uneven, making it difficult to fix them on a manual CMM workbench for measurement. Existing fixtures can only fix large products in place, but cannot fine-tune their position. This means that tilted products need to be repositioned. Furthermore, existing fixtures can only measure one product at a time, increasing measurement time, reducing efficiency, and potentially affecting delivery deadlines. Therefore, there is an urgent need to design a movable fixture to assist in the measurement of large products and solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a movable fixture for assisting in the measurement of large products, which solves the problems mentioned above, such as the inability to fix products with large areas, the inability to adjust their position when fixed, which seriously increases measurement time and intensity, reduces measurement efficiency, and reduces measurement accuracy due to the lack of re-measurement.

[0005] To solve the above-mentioned technical problems, this utility model provides a movable tooling for assisting in the measurement of large products, including a base frame and two sets of adjustment and positioning devices disposed on both sides of the base frame. Each set of adjustment and positioning devices includes several first positioning components and two sets of limiting components disposed on the same side of the base frame. The several first positioning components are respectively disposed on the periphery and inner side of the large product. Each set of limiting components includes a first mounting base, a first fixing base, and a first support. One side of the first mounting base is connected to the base frame, and the other side is connected to one side of the first fixing base. The other side of the first fixing base is connected to one side of the first support, and a first limiting plate and a second limiting plate are disposed thereon. A first pad is placed between the first support and the first limiting plate, and a second pad is placed between the first support and the second limiting plate. A first adjusting top support is inserted through the other side of the first support. The first adjusting top support is used to insert into the positioning hole on the large product to adjust the thickness of the first pad and the second pad, so as to adjust the lateral and longitudinal positions of the first support.

[0006] Furthermore, the number of the plurality of first positioning components is at least four, each first positioning component including a second fixing seat and a second support. One side of the second fixing seat is connected to the side of the first mounting seat, and the other side is connected to one side of the second support. A third limiting plate and a fourth limiting plate are also provided on the other side of the second fixing seat. A third pad is provided between the third limiting plate and the second support, and a fourth pad is provided between the fourth limiting plate and the second support. A second adjusting top support is provided inside the other side of the second support to adjust the thickness of the third pad and the fourth pad, so as to adjust the lateral and longitudinal positions of the second support.

[0007] Furthermore, a clamping assembly is provided on one side of the second fixed seat. The clamping assembly includes a second mounting seat and clamps. One side of the second mounting seat is connected to the base frame and is located on one side of the first mounting seat. The clamps are fixedly mounted on the other side of the second mounting seat. The clamps are used to cooperate with the second adjusting top support to clamp large products.

[0008] Furthermore, the base frame consists of a lower base frame and an upper base frame disposed on the lower base frame, wherein the width of the upper base frame is smaller than the width of the lower base frame.

[0009] Furthermore, the two sets of limiting components are arranged opposite to each other on the same side of the upper base frame, and are located at both ends of the large product.

[0010] Furthermore, the two sets of adjustment and positioning devices are arranged opposite to each other on both sides of the upper base frame.

[0011] Furthermore, several second positioning components are symmetrically arranged at both ends of the lower base frame.

[0012] Furthermore, each of the second positioning components includes a fixing plate, an L-shaped connecting plate, and a positioning pin. One side of the fixing plate is fixed to the end sidewall of the lower base frame, and the other side is fixed to the vertical connecting plate of the L-shaped connecting plate. The positioning pin is vertically inserted through the horizontal connecting plate of the L-shaped connecting plate, and its bottom extends out of the horizontal connecting plate.

[0013] Furthermore, the upper base frame is provided with lifting lugs on all four sides of the top and with several first moving wheels at the bottom.

[0014] Furthermore, the bottom of the lower base frame is provided with several second moving wheels, and each second moving wheel is provided with a brake plate.

[0015] The beneficial effects of this utility model are as follows: The design of two sets of adjustment and positioning devices on both sides of the base frame in this utility model enables the tooling of this application to inspect two large products at the same time, reducing the number of times to re-align and effectively improving the inspection efficiency.

[0016] The design of the two sets of limiting components allows the first adjusting top support to be inserted into the positioning hole of the large product, and the thickness of the first pad and the second pad to be adjusted to change the distance between the first support and the first limiting plate and the second limiting plate, thereby changing the lateral and longitudinal position of the first support, adjusting the position of the large product on the measuring equipment, reducing measurement time, and improving the detection efficiency of the large product.

[0017] The design of several first positioning components on the periphery and inner side of the large product allows it to be fixed on the periphery and inner side. At the same time, the distance between the bottom of the large product and the tooling base frame can be changed by adjusting the second adjusting top support. The thickness of the third and fourth pads can be used to change the distance between the second support and the third and fourth limiting plates, thereby changing the lateral and longitudinal position of the second support and adjusting the position of the large product on the measuring equipment. In addition, the design of the clamping assembly can clamp the large product to stabilize its position on the base frame, thereby improving the accuracy and testing efficiency of the large product.

[0018] The design of the lifting lugs on the top of the upper base frame allows it to be lifted onto or off the measuring equipment via a lifting mechanism, solving the problem that the combined weight of tooling and large products is too heavy to be easily lifted or lowered, and effectively reducing the labor intensity of workers.

[0019] The design of several first and second moving wheels and brake plates at the bottom of the upper and lower base frames allows the fixture to be fixed to large products using either a single upper base frame or by stacking two base frames together. This allows it to meet the usage requirements of different heights, improving the applicability of the fixture. It can also stop the fixture during measurement to avoid measurement errors caused by fixture movement or the risk of the probe being broken. Attached Figure Description

Detailed Implementation

[0027] The technical solutions in the embodiments 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, and 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.

[0028] In one specific embodiment of this utility model, such as Figures 1-5 As shown, a movable tooling for assisting in the measurement of large products is disclosed, including a base frame 1 and two sets of adjustment and positioning devices 2 arranged on both sides of the base frame 1. The design of the two sets of adjustment and positioning devices 2 arranged on both sides of the base frame 1 enables the tooling of this application to simultaneously inspect two large products, reducing the number of re-alignment points and effectively improving the inspection efficiency.

[0029] Each set of adjustment and positioning devices 2 includes several first positioning components 21 and two sets of limiting components 22 arranged on the same side of the base frame 1. Several first positioning components 21 are respectively arranged on the periphery and inner side of the large product. The design of several first positioning components 21 on the periphery and inner side of the large product enables it to fix the periphery and inner side of the large product.

[0030] Each set of limiting components 22 includes a first mounting base 221, a first fixing base 222, and a first support 223. One side of the first mounting base 221 is connected to the base frame 1, and the other side is connected to one side of the first fixing base 222. The other side of the first fixing base 222 is connected to one side of the first support 223, and a first limiting plate 2221 and a second limiting plate 2222 are provided on it. A first pad 224 is placed between the first support 223 and the first limiting plate 2221, and a second pad 225 is placed between the first support 223 and the second limiting plate 2222. A first adjusting top support 226 is inserted through the other side of the first support 223. The first adjusting top support 226 is used to insert into the positioning hole on the large product. The outer diameter of the first adjusting top support 226 is smaller than the inner diameter of the positioning hole. The thickness of the first pad 224 and the second pad 225 is adjusted to adjust the lateral and longitudinal positions of the first support 223, thereby adjusting the lateral and longitudinal positions of the large product.

[0031] The design of the two sets of limiting components 22 allows the first adjusting top support 226 to be inserted into the positioning hole of the large product, and the thickness of the first pad 224 and the second pad 225 to change the distance between the first support 223 and the first limiting plate 2221 and the second limiting plate 2222, thereby changing the lateral and longitudinal position of the first support 223, adjusting the position of the large product on the measuring equipment, reducing measurement time, and improving the detection efficiency of large products.

[0032] The number of first positioning components 21 is at least four. Each first positioning component 21 includes a second fixing seat 211 and a second support 212. One side of the second fixing seat 211 is connected to the side of the first mounting seat 221, and the other side is connected to one side of the second support 212. A third limiting plate 215 and a fourth limiting plate 216 are also provided on the other side of the second fixing seat 211. A third pad 217 is provided between the third limiting plate 215 and the second support 212, and a fourth pad 218 is provided between the fourth limiting plate 216 and the second support 212. A second adjusting top support 219 is provided inside the other side of the second support 212. Twisting the second adjusting top support 219 causes its head, which is in contact with the large product, to move away from or closer to the base frame 1, thereby adjusting the distance between the large product and the side of the base frame 1. At the same time, the thickness of the third pad 217 and the fourth pad 218 can also be adjusted to adjust the lateral and longitudinal positions of the second support 212.

[0033] The design of the aforementioned first positioning components 21 allows for adjustment of the distance between the bottom of the large product and the tooling base frame 1 by adjusting the second adjusting top support 219. Furthermore, the thickness of the third pad 217 and the fourth pad 218 can be used to change the distance between the second support 212 and the third limiting plate 215 and the fourth limiting plate 216, thereby changing the lateral and longitudinal positions of the second support 212 and adjusting the position of the large product on the measuring equipment. This allows for adjustment of the large product in three directions, improving the accuracy of the large product's position and enhancing measurement accuracy and efficiency.

[0034] The first fixing seat 222, the first limiting plate 2221 and the second limiting plate 2222 are integrally formed structures. The second fixing seat 211, the third limiting plate 215 and the fourth limiting plate 216 are also integrally formed structures. Both of these fixing seats are made of hard aluminum, which can increase the wear resistance of the fixing seats.

[0035] Adjusting bolts are provided on the side walls of the first limiting plate 2221, the second limiting plate 2222, the third limiting plate 215, and the fourth limiting plate 216. The insertion end of each adjusting bolt is screwed into the corresponding first pad 224, second pad 225, third pad 217, and fourth pad 218, so that the position of the first pad 224, second pad 225, third pad 217, and fourth pad 218 can be finely adjusted to meet the bidirectional adjustment requirements of large products.

[0036] The top of the first fixed base 222 is provided with a first waist-shaped through groove for cooperating with the fastener used to fix the first support 223, and the width of the first waist-shaped through groove is greater than the diameter of the fastener rod, so as to facilitate the bidirectional movement of the first support 223.

[0037] The top of the second fixed base 211 is provided with a second waist-shaped through groove for cooperating with the fastener used to fix the second support 212, and the width of the second waist-shaped through groove is greater than the diameter of the fastener rod, so as to facilitate the bidirectional movement of the second support 212.

[0038] The thicknesses of the first pad 224, the second pad 225, the third pad 217, or the fourth pad 218 differ by 0.1 mm.

[0039] A clamping assembly 214 is provided on one side of the second fixed base 211. The clamping assembly 214 includes a second mounting base 2141 and a clamp 2142. One side of the second mounting base 2141 is connected to the base frame 1 and is located on one side of the first mounting base 221. The clamp 2142 is fixedly mounted on the other side of the second mounting base 2141. The clamp 2142 is used to cooperate with the second adjusting top support 219 to clamp large products. The clamping assembly 214 is designed to clamp large products to stabilize the position of large products on the base frame 1 and improve the accuracy and testing efficiency of large products.

[0040] The base frame 1 includes a lower base frame 11 and an upper base frame 12 set on the lower base frame 11. Two sets of adjustment and positioning devices 2 are set opposite to each other on both sides of the upper base frame 12. The width of the upper base frame 12 is smaller than the width of the lower base frame 11. When only the height of the upper base frame 12 is needed to fix large products, the upper base frame 12 can be removed and used separately. The top of the upper base frame 12 is provided with lifting lugs 4. The design of the lifting lugs 4 on the top of the upper base frame 12 allows it to be lifted up or down from the measuring equipment by a lifting mechanism, so as to solve the problem that the combined weight of the tooling and large products is too heavy to be easily lifted or lowered, and effectively reduce the labor intensity of workers.

[0041] The bottom of the upper base frame 12 is provided with several first moving wheels 5, and each of the first moving wheels 5 is equipped with a brake to lock the first moving wheels 5.

[0042] Two sets of limiting components 22 are arranged opposite to each other on the same side of the upper base frame 12, and are located at both ends of the large product.

[0043] The bottom of the lower base frame 11 is provided with several second moving wheels 6, and each second moving wheel 6 is equipped with a brake plate 7. The design of several first moving wheels 5 and second moving wheels 6 and brake plates 7 at the bottom of the upper base frame 12 and the lower base frame 11 allows the tooling to be fixed to large products by using the upper base frame 12 alone, or by stacking two base frames together, so as to meet the usage requirements of different heights, improve the applicability of the tooling, and at the same time, it can also stop the tooling during measurement to avoid measurement errors caused by tooling movement or the risk of the probe being broken.

[0044] Several second positioning components 3 are symmetrically arranged at both ends of the lower base frame 11. Each second positioning component 3 includes a fixing plate 31, an L-shaped connecting plate and a positioning pin 33. One side of the fixing plate 31 is fixed to the end side wall of the lower base frame 11, and the other side is fixed to the vertical connecting plate 321 of the L-shaped connecting plate. The positioning pin 33 is vertically inserted into the horizontal connecting plate 322 of the L-shaped connecting plate, and its bottom extends out of the horizontal connecting plate 322.

[0045] Several second positioning components 3 can be installed on a fixed base on the test equipment to stabilize the base frame 1 and improve the stability of the tooling.

[0046] The working process of this utility model:

[0047] Based on the height of the large product to be measured, select the composition of the base frame 1. If a taller base frame 1 is required, install the upper base frame 12 onto the lower base frame 11. If a shorter base frame 1 is required, remove the lower base frame 11 and use only the upper base frame 12. After selection, lift the lifting lug 4 on the upper base frame 12 using the lifting mechanism and lift the selected base frame 1 onto the measuring equipment. A fixed platform can be placed on the workbench of the measuring equipment, and the positioning pin 33 of the second positioning component 3 can be inserted into the fixed platform. Alternatively, the first moving wheel 5 or the second moving wheel 6 can be braked directly. Either of the two fixing methods can be selected.

[0048] Simultaneously, the manual CMM is used to measure the positions of the first support 223 and the second support 212 on both sides of the base frame 1. When the measured values ​​deviate, the first support 223 and the second support 212 that deviate will be adjusted. The lateral or longitudinal position of the first support 223 and the second support 212 will be adjusted by adjusting the thickness of the corresponding first pad 224, second pad 225, third pad 217 or fourth pad 218. After the adjustment is completed, the positioning hole of the large product is fitted onto the first adjusting top support 226 of the limiting component 22 on one side of the upper base frame 12, and then... The clamp 2142 fixes the large product onto the second adjusting top support 219. If there is unevenness, the depth of the second adjusting top support 219 screwed into the second fixed seat 211 can be adjusted to adjust the fit between the large product and the second adjusting top support 219. The flatness of the large product can be tested by manually operating the CMM, thereby adjusting the screwing depth of the second adjusting top support 219 that is not on the same flatness, so that the large product can be on the same horizontal plane to meet the position requirements of the large product in three directions, thereby improving the accuracy and efficiency of the measurement of the large product.

[0049] Furthermore, two large products can be installed on both sides of the adjusted base frame 1, and the CMM can be manually operated at the same time to measure the two large products simultaneously, thereby improving the efficiency of product measurement.

[0050] Once the adjustment is complete, the fixture will not move. Therefore, it is only necessary to measure the position of the first support 223 to clearly know whether the fixture has shifted. If it has not shifted, it is only necessary to install two different large products onto the fixture and continuously measure the size of the large products, which effectively improves the measurement efficiency.

[0051] When there is a deviation between the first support 223 and the second support 212 on the tooling, the thickness of the corresponding first pad 224, second pad 225, third pad 217 or fourth pad 218 will be adjusted as needed to adjust the lateral or longitudinal position of the first support 223 and the second support 212 so that they can meet the measurement requirements.

[0052] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
