[0037] like Figures 1 to 5 As shown, this embodiment provides a clamping carrier, including a base 10, a cover plate 20 and a ballast assembly 30, wherein the base 10 is used to carry the product to be measured, the cover plate 20 is detachably stacked on the base 10, a ballast port 21 is penetrated through the cover plate 20, and the ballast assembly 30 includes a ballast block 31 movably arranged above the ballast port 21, the ballast block 31 has a locking position for pressing the cover plate 20 against the base 10 and an unlocking position for releasing the cover plate 20, and the projection of the ballast block 31 at the unlocking position on the cover plate 20 falls within the ballast port 21. Specifically, when the ballast block 31 is moved to the unlocked position, since the projection of the ballast block 31 on the cover plate 20 falls within the ballast port 21 at this time, the cover plate 20 can be removed from the base 10, the product to be measured is placed in, and the cover plate 20 is stacked and installed on the base 1, and then the ballast block 31 is moved to the locked position, so that the ballast block 31 presses the cover plate 20 against the base 10 to clamp and fix the product to be measured between the base 10 and the cover plate 20, and at the same time, pressure is applied to the product to be measured clamped between the cover plate 20 and the base 10 to correct slight deformation of the product to be measured produced during the production process, so that the measuring equipment can measure real and accurate dimensional data, and the product to be measured is clamped and fixed by the cover plate 20 and the base 10, so that when the contact measuring equipment is used to measure the size of the product, the product to be measured will not move due to contact force, thereby facilitating the measurement of effective data.

[0038] Specifically, the ballast assembly 30 also includes a guide sleeve 32 and a pull rod 33. One end of the guide sleeve 32 is fixedly arranged on the base 10, and the other end of the guide sleeve 32 extends into the ballast port 21. One end of the pull rod 33 is movably inserted into the guide sleeve 32, and the other end of the pull rod 33 passes through the guide sleeve 32 and is connected to the ballast block 31. When the ballast block 31 is in the locked position, the driving pull rod 33 moves axially toward the base 10 to apply pressure to the cover plate 20. The driving pull rod 33 rotates in the guide sleeve 32 to drive the guide block to switch between the locked position and the unlocked position. In this embodiment, the pull rod 33 is connected to the ballast block 31 by a latch 35, and its connection method is simple and easy to disassemble. Optionally, the connection method of the pull rod 33 and the ballast block 31 includes but is not limited to screws, bolts, welding or gluing, etc., which are not specifically limited here.

[0039] In this embodiment, the ballast assembly 30 also includes an elastic member 34, which is sleeved on the pull rod 33. A limiting portion is provided at one end of the pull rod 33 away from the ballast block 31. One end of the elastic member 34 abuts against the limiting portion, and the other end abuts against the inner top wall of the guide sleeve 32. When the clamping carrier provided by this embodiment is used to clamp the product to be measured, the initial state of the ballast block 31 is in the unlocked position, the cover plate 20 can be stacked on the base 10, and the projection of the ballast block 31 on the cover plate 20 falls within the ballast port 21. The operator first lifts the ballast block 31 connected to the pull rod 33 in a direction away from the cover plate 20. At this time, the limit portion of the pull rod 33 approaches the inner top wall of the guide sleeve 32, and the elastic member 34 is in a compressed state. Then the operator rotates the ballast block 31 so that part of the projection of the ballast block 31 on the cover plate 20 falls outside the ballast port 21, and then releases the ballast block 31. Under the elastic force of the elastic member 34, the pull rod 33 drives the ballast block 31 to press the cover plate 20. In order to apply uniform ballast force to the product to be measured, this embodiment uses four ballast assemblies 30 to apply pressure to the product to be measured, and the four ballast assemblies 30 are evenly distributed on the base 10, so as to avoid pressure concentration and damage to the product to be measured. In other embodiments, the number of ballast assemblies 30 may also be selected according to the shape and deformation of the product to be measured, which is not specifically limited here. Preferably, in the locked state, the pressure of each elastic member 34 driving the corresponding ballast assembly 30 to press the cover plate 20 is 10N, which can correct the deformation of the product to be measured without damaging the product to be measured. In other embodiments, the pressure of the elastic member 34 in the locked state can be adaptively selected according to the deformation and compressive performance of the product to be measured, which is not specifically limited here.

[0040] Preferably, the end face of the guide sleeve 32 extending into the ballast port 21 is provided with two limit grooves. When the ballast block 31 is in the locked position, the ballast block 31 is engaged with one of the limit grooves. When the ballast block 31 is in the unlocked position, the ballast block 31 is engaged with the other limit groove. The above arrangement enables the ballast block 31 to be stably in the locked position or the unlocked position without sliding at will.

[0041] like Figures 3-4 As shown, the base 10 is provided with a first reference hole 11, the cover plate 20 is provided with a second reference hole 22, and the product to be measured has a third reference hole. When the product to be measured is correctly loaded between the base 10 and the cover plate 20, the first reference hole 11, the third reference hole and the second reference hole 22 are coaxially connected in sequence. The operator can realize fast placement and rough positioning of the product to be measured and the cover plate 20 by aligning the first reference hole 11, the third reference hole and the second reference hole 22 in sequence. The measuring equipment can also determine the measurement reference through the first reference hole 11, the third reference hole and the second reference hole 22 that are coaxially connected in sequence.

[0042] Furthermore, the base 10 and the cover plate 20 are also provided with contoured holes adapted to the structure of the product to be measured, so that the product to be measured can fit tightly against the base 10 and the cover plate 20, making it convenient for the base 10 and the cover plate 20 to apply pressure to the product to be measured to correct its deformation.

[0043] Preferably, in order to facilitate the taking and placing of the cover plate 20, a handle 26 is further provided on the cover plate 20. The connection method between the handle 26 and the cover plate 20 includes but is not limited to screws, bolts or clamping, etc., which is not specifically limited here.

[0044] In this embodiment, the base 10 is provided with a stopper 12 that can be engaged with the groove on the product to be measured, and can limit the position of the product to be measured to prevent the product from sliding. In addition, the upper surface of the base 10 is provided with a contour groove 13 around its circumference, and the contour groove 13 is adapted to the outer edge of the product to be measured, which can further limit the position of the product, so that the product to be measured can fit the base 10 to avoid shaking.

[0045] In order to facilitate the measurement of the size data of the product to be measured, the base 10 is provided with a first avoidance structure 14 in the circumference, and the cover plate 20 is provided with a second avoidance structure 23 in the circumference, so that the product to be measured can be detected through the first avoidance structure 14 and the second avoidance structure 23. The first avoidance structure 14 and the second avoidance structure 23 can expose the points to be detected on the product, so that the measuring device can measure the points to be detected. In addition, the first avoidance structure 14 and the second avoidance structure 23 can also avoid the probe of the probe-type measuring device, so that it is convenient for it to measure.

[0046] Preferably, the base 10 is also provided with a positioning pin 15, one end of which is fixedly provided on the base 10; the cover plate 20 is provided with a positioning hole 24 which is plugged with the other end of the positioning pin 15, so that the cover plate 20 can be quickly and accurately docked with the base 10, avoiding the product to be measured from being crushed due to the misalignment of the cover plate 20. In this embodiment, one end of the positioning pin 15 is plugged into the base 10. Optionally, the connection method between the positioning pin 15 and the base 10 includes, but is not limited to, screws, bolts, or clamping, etc., which are not specifically limited here.

[0047] Furthermore, in order to prevent the positioning pin 15 from causing wear to the cover plate 20, the positioning hole 24 is also provided with a positioning sleeve 25, and the positioning pin 15 is plugged into the positioning sleeve 25. When the positioning pin 15 or the positioning sleeve 25 is worn, they can be replaced respectively, thereby extending the service life of the clamping carrier and reducing the production and maintenance costs.

[0048] When using some probe-type measuring equipment for measurement, due to the limited moving distance of the probe, it may sometimes be necessary to increase the height of the loading fixture so that the product to be measured is within the contact range of the probe. Therefore, the clamping carrier provided in this embodiment also includes a bottom plate 40, and the base 10 is detachably mounted on the bottom plate 40. The bottom plate 40 can increase the height of the clamping carrier, so that the clamping carrier provided in this embodiment is suitable for a variety of measuring equipment. Further, a plurality of support columns 50 are detachably supported and arranged below the bottom plate 40, which can further increase the height of the clamping carrier and improve the versatility of the clamping carrier.

[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
