[0016] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.
[0017] like Figures 1 to 3 As shown in FIG, it is a schematic diagram of the structure of the rapid positioning jig for injection molded products provided by the present invention. The rapid positioning jig for injection molded products includes a horizontal positioning component 10 and a crimping component 20 arranged on top of the horizontal positioning component 10. The rapid positioning jig for injection molded products also includes some other functional modules, such as a mounting structure arranged on the horizontal positioning component 10 and used to fix the horizontal positioning component 10 on the surface of the mounting table, etc., which should be technologies well known to those skilled in the art and will not be described in detail here.
[0018] It should be noted that this positioning fixture is used for products with specific shapes, such as Figure 2 As shown, the product 30 comprises an L-shaped body 31, two legs 32 positioned at the corners of the body 31, and curved portions 33 located on the body 31. The legs 32 are provided with protrusions 321 for easy engagement and position retention. The curved portions 33 protrude inwardly from the L-shaped body 31. The product 30 also includes all other structures, which are not relevant to clamping and are therefore not described here, but are simply labeled in the figure.
[0019] The horizontal positioning assembly 10 includes a base 11, two receiving grooves 12 opened on the top of the base 11, two limiting seats 13 respectively arranged on the bottom of each of the receiving grooves 12, two receiving grooves 14 respectively arranged on one side of the limiting seats 13, a pad 15 arranged on the top of the base 11, and a limiting rod 16 arranged on the top of the base 11.
[0020] The base 11 is used to hold products. In this embodiment, two bases 11 are spaced apart and arranged on top of a base plate 111. The operator can place two products on the corresponding bases 11 in sequence, thereby reducing the number of times to pick up the products and saving time. The bottom of the base plate 111 is symmetrically provided with a handle groove 112, making it easy for the operator to reach into the handle groove 112 and lift the base plate 111.
[0021] The receiving groove 12 is used to accommodate the two legs 32 of the product 30. When the product 30 is placed on the horizontal positioning assembly 10, one side of the L-shaped main body 31 is horizontal or approximately horizontal, while the other side is vertical or approximately vertical, thereby facilitating subsequent surface processing of the product 30. The width of the receiving groove 12 is greater than the width of the legs 32, thereby ensuring that the receiving groove 12 can fully accommodate the product 30.
[0022] The limit seat 13 is installed at the bottom of the receiving groove 12 by bolts and detachable threads, and is used to limit the movement of the product 30 on the horizontal plane. The cross section of the limit seat 13 is a rounded rectangular shape. One end of the limit seat 13 abuts against the support foot of the product 30.
[0023] The receiving groove 14 is provided on a side of the receiving groove 12 close to the workpiece 30 for receiving the protrusion 321 on the support leg 32 of the workpiece 30. The side wall of the support leg 32 abuts against one side of the limiting seat 13, and the bottom of the support leg 32 contacts the bottom of the limiting seat 13.
[0024] The pad 15 corresponds to the curved portion 33 of the product 30 and is used to support the curved portion 33. The top of the pad 15 is a horizontal surface. The pad 15 can be made of rubber to increase friction with the product 30, preventing the product 30 from moving on the horizontal surface. The rubber material can also be used with curved portions 33 of varying degrees of curvature, providing a better fit to the product 30 and preventing concentrated force on the product 30, which could cause deformation or damage.
[0025] The limiting rod 16 is vertically arranged on the top of the base 11, and is used to limit the position of the product 30 on the horizontal plane when the product 30 is placed on the top of the base 11. The corresponding side of the product 30 is abutted against the limiting rod 16, so that the position of the product 30 on the base 11 can be unique, thereby facilitating the crimping and subsequent processing of the crimping assembly 20. In this embodiment, the limiting rod 16 is located at the top of the accommodating groove 12, so that the top of the limiting rod 16 does not exceed the top surface of the base 11 too much, making it difficult for external debris to directly hit the limiting rod 16, and making it difficult for the limiting rod 16 to be damaged by the impact of foreign objects. The material of the limiting rod 16 can be rubber, so that it is not easy to smash the product 30 when the product 30 comes into contact.
[0026] The crimping assembly 20 includes a rotating rod 21 vertically arranged on the top of the base, a limiting portion 22 sleeved on the top of the rotating rod 21, a pressure rod 23 rotatably sleeved on the rotating rod 21, a spring 24 sleeved on the outside of the rotating rod 21 and with both ends respectively abutting against the limiting portion 22 and the pressure rod 23, a clamping head 25 arranged at the end of the pressure rod 23, and a pressure rod limiting rod 26 arranged on the top of the base 11.
[0027] The rotating rod 21 is used to provide an installation position for the pressing rod 23. It should be noted that, since the product 30 is designed to be axisymmetric, when the product 30 is installed on the base 11, the rotating rod 21 is located on the symmetry plane of the product 30. Moreover, when the pressing rod 23 is rotated to a preset position, the extension direction of the pressing rod 23 is parallel to the symmetry plane of the product 30, and the pressing position of the clamping head 25 is also symmetrical along the symmetry plane of the product 30, thereby ensuring uniform pressure on the product 30.
[0028] The limiting portion 22 is used to cooperate with the spring 24 described below, thereby pushing the pressing rod 23 toward the product 30 , so that the pressing rod 23 presses the product 30 onto the top of the base 11 .
[0029] The pressing rod 23 is used to fix and press the product 30 onto the base 11. The end of the pressing rod 23 is tilted downward to cooperate with the clamping head 25 to apply pressure on the middle of the product 30.
[0030] The spring 24 is used to provide pressure for the pressure rod 23 . When the spring 24 is in a naturally extended state, the pressing point of the pressure rod 23 is lower than the height of the pressing point of the product 30 .
[0031] The clamping head 25 is made of rubber and directly contacts the product 30 , thereby press-fitting the product 30 onto the base 11 .
[0032] The pressure rod limiting rod 26 is used to limit the rotational position of the pressure rod 23. When the pressure rod limiting rod 26 is rotated to release the pressure rod limiting rod 26 and is blocked by the pressure rod limiting rod 26 and cannot continue to rotate, the extension direction of the pressure rod 23 is exactly parallel to the symmetry plane of the product 30, thereby applying uniform pressure to the product 30. The top of the base 11 is provided with two sockets 261, which are symmetrically arranged on both sides of the rotation rod. The pressure rod limiting rod 26 can be selectively inserted into one of the sockets 261, thereby selectively limiting the rotational direction of the pressure rod 23. Alternatively, after the pressure rod 23 clamps the product 30, a pressure rod limiting rod 26 can be inserted into each of the two sockets 261 to prevent the pressure rod 23 from rotating loose and causing unstable clamping of the product 30.
[0033] During use, the pressure rod 23 is first rotated away from the base 11. The product 30 is then placed on top of the base 11 in the correct orientation. The two legs 32 of the product 30 abut against one side of the stopper 13, the protrusion 321 is located within the receiving groove 14, and the arcuate portion 33 contacts the pad 15, pushing the product 30 horizontally until it abuts against the stopper 16, thereby positioning the product 30 horizontally. The pressure rod 23 is then lifted, causing the spring 24 to compress, rotating the pressure rod 23 until it abuts against the pressure rod stopper 26. The extension direction of the pressure rod 23 is now parallel to the symmetry plane of the product 30. The operator then simply releases the pressure rod 23, which, under the action of the spring 24, presses against the surface of the product 30, thereby positioning the product 30 vertically.
[0034] Compared with the prior art, the quick positioning jig for injection molded products provided by the present invention is capable of accommodating and fixing the legs 32 of the product 30 by providing the accommodating groove 12, so that the L-shaped inner side of the product 30 can be unfolded upward, which is convenient for subsequent processing. A limiting seat 13 is respectively provided in each of the accommodating grooves 12, and at the same time, a limiting rod 16 provided in the accommodating groove 11 is cooperated to limit the horizontal movement of the legs 32 of the product 30. A accommodating groove 14 is provided in the accommodating groove 12, so as to accommodate the protrusion 321 on the product 30, thereby preventing the protrusion 321 from directly contacting the protrusion 321. The base 11 is contacted and deformed by pressure, and the crimping assembly 20 can press the product 30 onto the base 11, so that the product 30 is stably placed on the base 11. Specifically, the crimping assembly 20 includes a rotating rod 21 arranged on the top of the base, a limiting portion 22 mounted on the top of the rotating rod 21, and a pressure rod 23 rotatably mounted on the rotating rod 21. A spring 24 is provided between the pressure rod 23 and the limiting portion 22. The operator rotates the pressure rod 23 to the top of the product 30, and the pressure rod 23 will be pressed onto the surface of the product 30 under the action of the rebound force of the spring 24.
[0035] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
