In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0064] The following is a detailed description of the caliper cylinder processing fixture provided in the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0065] Embodiment 1:

[0066] like Figures 1 to 6As shown, the embodiment of the present application provides a clamp for machining a caliper cylinder body, including a workbench 1 and a clamping device 2, wherein the clamping device 2 includes a lifting platform 21, which can be lifted and installed on the workbench 1, with a groove 22 on the top and notches 23 on both sides; a pair of standing frames 24, symmetrically fixed on the top of the workbench 1, and movably matched with the corresponding notches 23; a pair of clamping plates 25, which can be slidably installed in a pair of standing frames 24, respectively, and the top ends of the opposite side walls are each provided with a pressing plate 26, and the bottom ends of the opposite side walls are connected to the lifting platform 21 through a transmission member 3. Transmission connection; a rotating drum 27, which is rotatably mounted outside the lifting platform 21 and a pair of vertical frames 24, and is transmission-connected to a pair of clamps 25 through a transmission mechanism 4, and is used to control the closing and separation of the pair of clamps 25; a horizontal handle 28, which is fixed on the peripheral wall of the rotating drum 27; a locking mechanism 5, which includes a locking member 51 for engaging with the rotating drum 27 and an unlocking member 52 for releasing the engagement state of the locking member 51 and the rotating drum 27. When the pair of clamps 25 are closed / separated, the lifting platform 21 is controlled to rise / descend through the transmission member 3.

[0067] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the shape of the groove 22 is adapted to the bottom of the caliper cylinder 100. When fixing the caliper cylinder 100, the bottom of the caliper cylinder 100 is first placed in the groove 22, and then the rotary drum 27 is rotated by the horizontal handle 28, and the transmission mechanism 4 controls a pair of clamping plates 25 to slide in the corresponding vertical frame 24 toward the caliper cylinder 100. At the same time, the transmission member 3 drives the lifting platform 21 to rise, and finally the bottom of the caliper cylinder 100 is tightly pressed against the groove 22, the left and right sides are tightly pressed against the clamping plates 25 on both sides, and the top is tightly pressed against a pair of The bottom surface of the pressure plate 26 is pressed tightly, and at this time, the engaging member 51 is engaged with the rotating drum 27, and the rotating drum 27 cannot rotate, so that the caliper cylinder 100 is kept in a fixed state. When the fixed state of the caliper cylinder 100 needs to be released, the unlocking member 52 is operated to release the engagement between the engaging member 51 and the rotating drum 27, and then the rotating drum 27 is reversed by rotating the horizontal handle 28. Under the action of the transmission mechanism 4 and the transmission member 3, a pair of clamping plates 25 are separated, and a pair of pressure plates 26 are retracted into the corresponding inner cavities of the vertical frames 24. The lifting platform 21 is lowered, and the caliper cylinder 100 can be taken out.

[0068] Embodiment 2:

[0069] like Figures 2 to 6 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the transmission member 3 includes a top block 31, which is fixed on the bottom surface of the lifting platform 21, and the left and right end surfaces are both inclined downward and correspond to the two side clamps 25; a pair of push blocks 32, which are respectively fixed on the lower ends of the opposite side walls of each clamp 25, and the outer end surfaces are inclined upward; a separation elastic member 33, which is used to apply a separation thrust to the opposite side walls of a pair of clamps 25; and a downward pressing elastic member 34, which is used to apply a downward pulling force to the lifting platform 21.

[0070] Furthermore, the separation elastic member 33 includes a support block 331 , which is fixed on the top surface of the workbench 1 and located below the top block 31 ; and a plurality of separation springs 332 , which are respectively arranged between the bottom of the opposite side wall of each clamping plate 25 and the end surface of the support block 331 .

[0071] Furthermore, the downward pressure elastic member 34 includes a pair of sliding holes, which are arranged on the bottom surface of the workbench 1; a pair of downward pressure rods 341, whose top ends are symmetrically fixed on the bottom surface of the lifting platform 21, and whose lower ends pass through the top surface of the workbench 1 and extend into the corresponding sliding holes and are fixed with a bottom plate 342; a pair of downward pressure springs 343, which are respectively sleeved on the circumference of each downward pressure rod 341, and whose top ends and bottom ends are respectively pressed against the top ends of the corresponding sliding holes and the top surfaces of the corresponding bottom plates 342.

[0072] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the rotating drum 27 cooperates with the transmission mechanism 4 to control the pair of clamping plates 25 to approach each other, each separation spring 332 is compressed and shortened, and the pair of push blocks 32 approach each other and cooperate with the inclined end surface of the top block 31 to push the top block 31, the lifting platform 21, the pair of downward pressure rods 341 and the pair of bottom plates 342 to rise, and each downward pressure spring 343 is also compressed and shortened. When the rotating drum 27 is reversed, each separation spring 332 releases elastic potential energy to push the pair of clamping plates 25 to separate, and accordingly, the pair of push blocks 32 also separate from each other and gradually break away from contact with the end surface of the top block 31. Each downward pressure spring 343 simultaneously releases elastic potential energy to push the pair of bottom plates 342, the pair of downward pressure rods 341, the lifting platform 21 and the top block 31 to descend until the bottom surface of the top block 31 contacts the top surface of the support block 331, and the lifting platform 21 descends to the lowest position.

[0073] Embodiment 3:

[0074] like Figures 5 and 6 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the transmission mechanism 4 includes: a pair of transmission grooves 41, respectively arranged on the opposite side walls of each clamping plate 25, and the inner sides of the upper and lower ends are both provided with inclined guide surfaces 42; an internal thread, which is arranged on the inner circumferential wall of the rotating cylinder 27, and the thread directions of the upper and lower parts are opposite; a pair of lower separation blocks 43, respectively mounted on the lower part of the inner cavity of each vertical frame 24 for lifting and sliding; a pair of upper separation blocks 44, respectively mounted on the upper part of the inner cavity of each vertical frame 24 for lifting and sliding, and the outer side walls of the pair of lower separation blocks 43 and the pair of upper separation blocks 44 are both provided with threads that are transmission-connected to the internal threads.

[0075] Furthermore, it also includes a pair of cover shells 61, which are fixed on the top of the outer side of each vertical frame 24, and the bottom surface is in sliding contact with the top surface of the rotating drum 27; a pair of notches 62, which are respectively arranged on each upper separation block 44; a pair of slide groove openings 63, which are symmetrically arranged on each clamping plate 25; a pair of fixed columns 64, one end of which is respectively fixed on the inner wall of each cover shell 61, and the outer end slides through the corresponding notches 62 and the slide groove openings 63; a pair of rollers 65, which are rotatably installed on the outer ends of each fixed column 64.

[0076] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the rotating drum 27 rotates, the internal thread on its inner wall rotates at the same time. Since the upper part of the internal thread is in opposite directions to the lower part, the upper separation block 44 that is threadedly matched with the upper part of the internal thread and the lower separation block 43 that is threadedly matched with the lower part of the internal thread will move relatively. When the upper separation block 44 rises, the lower separation block 43 falls. At this time, the upper separation block 44 and the lower separation block 43 respectively cooperate with the inclined guide surfaces 42 on the inner sides of the upper and lower ends of the transmission groove 41 to push the clamping plate 25 to move toward the caliper cylinder 100. Conversely, when the rotating drum 27 is reversed, the upper separation block 44 and the lower separation block 43 approach each other and gradually break away from the contact with the corresponding inclined guide surfaces 42. Each separation spring 332 can release its elastic potential energy to push the clamping plate 25 to move away from the caliper cylinder 100.

[0077] When the caliper cylinder 100 is lifted or lowered between a pair of vertical frames 24, its side walls facing the vertical plates on both sides respectively roll and rub against the rollers 65, so as to prevent the left and right side walls of the caliper cylinder 100 from being scratched against the inner surface of the vertical frames 24 when the caliper cylinder 100 is lifted or lowered between the pair of vertical plates, and to position the left and right sides of the caliper cylinder 100, so as to prevent it from tilting during the fixing process;

[0078] The opposite side walls of the vertical frame 24 are provided with longitudinal grooves and a plurality of transverse grooves. The upper separation block 44 and the lower separation block 43 are provided with longitudinal sliders on both sides for sliding cooperation with the corresponding longitudinal grooves. The left and right sides of the clamping plate 25 are provided with a plurality of transverse sliders for sliding cooperation with the transverse grooves to ensure that the upper separation block 44 and the lower separation block 43 are stably lifted and lowered in the inner cavity of the vertical frame 24. The threads on the outer wall are tightly matched with the internal threads of the inner circumferential wall of the rotating drum to ensure that the clamping plate 25 slides stably in the vertical frame 24.

[0079] Embodiment 4:

[0080] like Figures 3 to 5 As shown, in the present embodiment, in addition to the structural features of the aforementioned embodiments, the engaging member 51 includes an anti-slip ring groove 511, which is arranged on the top surface of the workbench 1 and slidingly cooperates with the bottom of the rotating drum 27; a locking slot 512, which is arranged on one side of the bottom of the rotating drum 27; a lifting slot 513, which is arranged in the workbench 1 and is connected to the anti-slip ring groove 511 at the top; a lifting block 514, which is movably installed in the lifting slot 513 and the locking slot 512 through a lifting spring 515; and a side groove 516, which is arranged on the side wall of the lifting block 514 away from the lifting platform 21, and the lower end surface is inclined outward, and is used to cooperate with the unlocking member 52 to control the descent of the lifting block 514.

[0081] Furthermore, the unlocking member 52 includes a lower rack 521, which is slidably installed in the workbench 1 through a lower slide groove, and one end of which can extend into the lifting groove 513 and the side groove 516; an upper rack 522, which is slidably installed in the workbench 1 through an upper slide groove, is located above the lower slide groove, and a return spring is provided between the end away from the lifting groove 513 and the end of the upper slide groove; a gear 523, which is rotatably installed in the workbench 1 through a connecting cavity, and meshes with the upper rack 522 and the lower rack 521; a connecting groove, which is arranged on the top surface of the workbench 1 and is connected with the upper slide groove; a mounting platform 524, which is fixed on the top of the upper rack 522, is slidably installed in the connecting groove, and a column 525 is fixed on the top.

[0082] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the rotating drum 27 rotates, its bottom rotates in the anti-slip ring groove 511, and the lifting spring 515 continuously applies an upward thrust to the lifting block 514, so that the top of the lifting block 514 slides and rubs with the bottom end of the rotating drum 27 until the locking groove 512 at the bottom of the rotating drum 27 rotates to correspond to the lifting groove 513. At this time, under the action of the lifting spring 515, the top of the lifting block 514 is inserted into the locking groove 512, and the end surface of the lower rack 521 extending into the lifting groove 513 contacts the lower end surface inclined outwardly of the side groove 516. At this time, the rotating drum 27 is fixed. When it is necessary to release the fixed state of the rotating drum 27, the column 525 is pulled away from the rotating drum 27, and the mounting platform 524 and the upper rack 522 are moved away from the rotating drum 2 7, the gear 523 rotates, driving the lower rack 521 to slide toward the rotating drum 27, and the end of the lower rack 521 extending into the lifting groove 513 cooperates with the lower end surface of the side groove 516 inclined outward, pushing the lifting block 514 down until the side wall of the mounting platform 524 contacts the end surface of the connecting groove away from the rotating drum 27. At this time, the upper end of the lifting block 514 is completely separated from the locking groove 512, and the return spring is compressed and shortened. Then, the rotating drum 27 is driven to rotate in the opposite direction through the horizontal handle 28 until the locking groove 512 is away from the lifting block 514, and the column 525 can be released. Under the action of the return spring, the upper rack 522 is pushed to slide toward the rotating drum 27, and the gear 523 drives the lower rack 521 to rotate in the direction away from the lifting groove 513 to achieve reset.
