[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION
[0021] See also Figure 1 The plastic product 1 includes two first protrusions 11 at one end thereof, two grooves 12 in the middle thereof, and a second protrusion 13 disposed in the groove 12. A hole 111 is formed in the first protrusion 11, and the two holes 111 are coaxially arranged; the first protrusion 11 and the second protrusion 13 are arranged in parallel.
[0022] Plastic product 1 is connected to another product (not shown) via hole 331 and second boss 13. The distance between second boss 13 and hole 111 is crucial. Furthermore, during the ejection or transfer process after injection molding, first boss 11 may undergo slight deformation. To ensure proper fit between plastic product 1 and other products, the distance from the center of hole 111 after correction to first boss 11 can be measured to verify that plastic product 1 meets requirements.
[0023] See also Figures 2 to 5 , this embodiment provides an auxiliary correction measurement fixture, including a base 2, a clamping assembly 3 and two sliders 4.
[0024] A positioning seat 5 is provided in the middle of the top wall of the base 2, and the plastic product 1 to be measured is placed on the positioning seat 5. Four supporting legs 21 are provided on the bottom wall of the base 2, and the four supporting legs 21 are respectively provided on the four corners of the base 2.
[0025] Two sliders 4 are positioned opposite each other on one side of a positioning seat 5. Correction rods 41 are protruding from these opposing sides of the sliders 4. These rods 41 are coaxially arranged near the positioning seat 5 and are designed to be inserted into corresponding holes 111 of the plastic product 1 to correct the problem. The rods 41 can move toward and away from each other, facilitating installation and replacement of the plastic product 1.
[0026] The clamping assembly 3 is arranged on the other side of the positioning seat 5. The clamping assembly 3 includes a clamping block 31. One end of the clamping block 31 extends above the positioning seat 5. The clamping block 31 can move towards and away from the positioning seat 5, and is used to stably fix the clamping block 31 on the positioning seat 5.
[0027] In order to achieve relative movement of the two sliders 4 , a guide rail 22 is provided on the base 2 . The guide rail 22 is arranged parallel to the correction rod 41 , and the two sliders 4 are both slidably arranged on the guide rail 22 .
[0028] The movement of the sliders 4 can be driven manually or by a power device such as a pneumatic cylinder, hydraulic cylinder, or motor. The former is preferred in this embodiment. Specifically, a first elastic member 6 is connected between the two sliders 4. The first elastic member 6 is preferably a tension spring. Under normal conditions, the two sliders 4 are close to each other. Under the action of an external force, the two sliders 4 can move away from each other. When the external force decreases or disappears, the two sliders 4 can move closer together, causing the two correction rods 41 to tend to move closer together, ensuring that they can be inserted into the hole 111.
[0029] The clamping block 31 of this embodiment can move from top to bottom to compress the plastic product 1 to prevent the plastic product 1 from moving.
[0030] In order to facilitate the installation and replacement of the plastic product 1, the clamping block 31 of this embodiment can also rotate horizontally. When the plastic product 1 needs to be replaced, the clamping block 31 can be rotated to the outside of the positioning seat 5, which makes it easy to take the plastic product 1 in and out. After the plastic product 1 is placed on the positioning seat 5, the clamping block 31 can be rotated to the top of the positioning seat 5, at which point the clamping block 31 can press the plastic product 1 tightly. Specifically:
[0031] The clamping assembly 3 also includes a connector 32, a mounting sleeve 33, and a second elastic member 34. The mounting sleeve 33 extends through the base 2 and is fixedly attached thereto. A through-hole 331 is provided at the upper end of the mounting sleeve 33. The diameter of the through-hole 331 is smaller than the inner diameter of the mounting sleeve 33, resulting in an annular stop surface 332 formed around the outer periphery of the through-hole 331. The first end of the connector 32 is inserted into the mounting sleeve 33. The second end of the connector 32 extends upward through the through-hole 331 and connects to one end of the clamping block 31. The first end of the connector 32 is provided with a head 321, the outer diameter of which is larger than the outer diameter of the first end of the connector 32. The second elastic member 34 is preferably a compression spring. The second elastic member 34 is arranged in the mounting sleeve 33. The second elastic member 34 elastically abuts between the end portion 321 and the annular stop surface 332, so that the connecting member 32 can elastically move along the axial direction of the mounting sleeve 33, ensuring that under normal conditions, the clamping block 31 is in a low position to press the plastic product 1 on the positioning seat 5.
[0032] In this embodiment, the connecting member 32 is loosely fitted with the through hole 331 , so that the connecting member 32 and the mounting sleeve 33 are rotatably connected, and the clamping block 31 can rotate around the connecting member 32 , making it easier to take the plastic product 1 in and out.
[0033] Combine Figure 2 and Figure 6 The position of the positioning seat 5 on the base 2 is adjustable in a direction perpendicular to the correction rod 41, so that when the plastic product 1 is placed on the positioning seat 5, the hole 111 in the plastic product 1 can be aligned with the correction rod 41. Specifically, the positioning seat 5 has four first mounting holes 51, each of which is an elongated hole with its length perpendicular to the axial direction of the correction rod 41. The base 2 has second mounting holes corresponding to the first mounting holes 51. The positioning seat 5 is connected to the base 2 via bolts passing through the first mounting holes 51. The relative position of the bolts within the first mounting holes 51 is adjustable.
[0034] The positioning base 5 is provided with a support portion 52, an escape groove 53, a raised portion 54, and two stoppers 55. The plastic product 1 is placed on the support portion 52. The escape groove 53 and the raised portion 54 are respectively provided on opposite sides of the support portion 52, and the two stoppers 55 are respectively provided on the other opposite sides of the support portion 52. The raised portion 54 and the stoppers 55 both protrude from the support portion 52, while the escape groove 53 is recessed into the upper surface of the support portion 52. The escape groove 53 and the raised portion 54 both position the plastic product 1 in a first direction, while the two stoppers 55 position the plastic product 1 in a second direction.
[0035] In summary, the present invention provides a clamping block for clamping the plastic product to be measured on the positioning seat, thereby preventing the plastic product to be measured from moving and facilitating the measurement of its size; and provides a correction rod for cooperating with the hole of the plastic product to be measured, which, on the one hand, plays a correction role, and on the other hand, facilitates and accurately measures the size from the second boss to the hole on the plastic product, thereby improving measurement accuracy.
[0036] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
