[0031] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0032] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0033] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0034] The embodiment of the present utility model provides an internal support type fixing fixture for a throttle valve, such as Figure 2-5 As shown, the clamp comprises a base plate 100, an inner support assembly 200 fixed to the base plate 100, a plurality of support bases 300, a position limiting assembly 400, and a transverse pushing assembly 500. The support base 300 can be arranged around the inner support assembly 200. When using the clamp of this embodiment, the throttle valve is placed on the support base 300, and the support base 300 is used to support the throttle valve. The position limiting assembly 400 and the transverse pushing assembly 500 are respectively located on either side of the throttle valve. The transverse pushing assembly 500 is used to push the throttle valve laterally, thereby clamping the throttle valve together with the position limiting assembly 400, limiting lateral movement of the throttle valve and improving the clamping effect of the throttle valve.

[0035] The inner support assembly 200 includes a fixed cylinder 210, an inner support ring 220 sleeved on the outer side of the fixed cylinder 210, and an inner support driving mechanism 230 connected to the inner support ring 220. When using the clamp of this embodiment, the throttle valve is placed on the support seat 300, and the fixed cylinder 210 and the inner support ring 220 are inserted into the valve channel of the throttle valve. After that, the transverse push assembly 500 and the inner support driving mechanism 230 begin to operate. The transverse push assembly 500 and the limit assembly 400 jointly clamp the throttle valve, and the inner support driving mechanism 230 drives the inner support ring 220 to deform radially, so that the inner support ring 220 abuts the inner wall of the valve channel, thereby clamping the throttle valve with internal support.

[0036] Therefore, this embodiment does not require the use of excessive clamping mechanisms, and the overall structure is simpler than existing clamps. Furthermore, the inner support assembly 200, the plurality of support seats 300, the position limiting assembly 400, and the horizontal thrust assembly 500 can work together to stably clamp the throttle valve, ensuring smooth subsequent processing of the throttle valve.

[0037] In some embodiments, the fixed cylinder 210 includes a guide portion 211 located at its upper end. In the downward extending direction, the outer diameter of the guide portion 211 gradually increases, so that the cross-sectional shape of the guide portion 211 is similar to a truncated cone. The inner support ring 220 is sleeved on the guide portion 211, and the inner support driving mechanism 230 is used to drive the inner support ring 220 to move axially along the fixed cylinder 210.

[0038] When the inner support driving mechanism 230 drives the inner support ring 220 to move axially downwardly relative to the fixed cylinder 210, the outer diameter of the guide portion 211 gradually increases, correspondingly expanding the inner support ring 220. This increases the outer diameter of the inner support ring 220, allowing it to abut against the inner wall of the throttle valve valve passage, thereby supporting and clamping the throttle valve. Conversely, when the inner support driving mechanism 230 drives the inner support ring 220 to move axially upward relative to the fixed cylinder 210, the outer diameter of the inner support ring 220 gradually decreases, thereby loosening its grip on the throttle valve.

[0039] A portion of the inner side surface of the inner support ring 220 may be provided with a truncated cone shape that matches the guide portion 211 , so that the inner support ring 220 can be closely attached to the surface of the guide portion 211 and can be more easily moved on the surface of the guide portion 211 .

[0040] Furthermore, the inner support drive mechanism 230 includes a connecting seat 231 and an inner support driver 232. The connecting seat 231 passes through the fixed cylinder 210 and is connected to the inner support driver 232. The upper end of the connecting seat 231 extends above the fixed cylinder 210. An annular groove is provided on the outer circumference of the upper end of the connecting seat 231, and the annular groove surrounds the outer circumference of the connecting seat 231. A retaining ring 223 is provided on the inner side of the inner support ring 220. The retaining ring 223 surrounds the inner wall of the inner support ring 220 and is adapted to the annular groove. The retaining ring 223 is inserted into the annular groove, so that the connecting seat 231 and the inner support ring 220 are fixed together. The inner support driver 232 is used to drive the connecting seat 231 to move axially along the fixed cylinder 210, which in turn drives the inner support ring 220 to move axially along the fixed cylinder 210.

[0041] In this embodiment, the connecting seat 231 can be integrally formed or a split structure composed of multiple components. The internal support driver 232 can be a cylinder.

[0042] In some embodiments, the inner support ring 220 is provided with a plurality of through-holes. The hole-avoiding grooves can weaken the structural strength of the inner support ring 220, making it easier to deform and expand, so as to internally support and clamp the throttle valve.

[0043] Furthermore, the air avoidance groove includes a first air avoidance groove 221 and a second air avoidance groove 222. The first air avoidance groove 221 extends downward from the top of the inner support ring 220, and the second air avoidance groove 222 extends upward from the bottom of the inner support ring 220. The first air avoidance groove 221 and the second air avoidance groove 222 are evenly spaced along the circumference of the inner support ring 220, so that the deformation characteristics of the inner support ring 220 remain relatively uniform, so that it can be evenly expanded, and the clamping effect on the throttle valve is better.

[0044] In some embodiments, as Figure 2 、 Figure 3 and Figure 6 As shown, a positioning assembly 600 is also fixed to the base plate 100. The positioning assembly 600 includes a positioning seat 610 and an elastic pin 620 disposed on the positioning seat 610. The elastic pin 620 can elastically expand and contract in the transverse direction to abut the throttle. When the throttle is placed on the fixture of this embodiment, the elastic pin 620 abuts the throttle under the action of elastic force, pre-positioning the throttle so that it is initially in a relatively ideal position. The internal support assembly 200 can more stably support and clamp the throttle, and the horizontal push assembly 500 can accurately push the throttle.

[0045] A positioning hole may be provided on the positioning seat 610 , and the elastic pin 620 is passed through the positioning hole. An elastic member is also provided in the positioning hole, and the elastic member abuts against the elastic pin 620 and the inner wall of the positioning hole, so that the elastic pin 620 can elastically expand and contract in the transverse direction.

[0046] In some embodiments, as Figure 2 、 Figure 3 and Figure 7 As shown, the limit assembly 400 includes a limit seat 410 and a limit rod 420 fixed on the limit seat 410. The limit seat 410 is arranged on the outside of the throttle valve, and the limit rod 420 can extend laterally. When the horizontal push assembly 500 pushes the throttle valve, the limit rod 420 abuts against the throttle valve, thereby clamping the throttle valve with the horizontal push assembly 500.

[0047] In some embodiments, as Figure 2 、 Figure 3 and Figure 8 As shown, the push assembly 500 includes a push rod 510 arranged in a transverse direction and a push driver 520 connected to the push rod 510. The push driver 520 is used to drive the push rod 510 to move in a transverse direction, so that the push rod 510 can push the throttle. The push driver 520 can be a cylinder.

[0048] In some embodiments, as Figure 2 、 Figure 3 and Figure 9 As shown, a groove may be provided on the support seat 300, and the groove may avoid the protruding structure on the surface of the throttle valve to stably place the throttle valve. At the same time, under the premise of ensuring the structural strength, the material used in the support seat 300 may be reduced, thereby reducing the manufacturing cost.

[0049] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
