For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0025] The utility model provides the following technical solutions: Example 1
[0026] Combine Figures 1 to 4 , an anti-deflection fixture for processing a valve core of an injection pump, comprising a mounting plate 1, a support box 2 fixedly connected to the inner side of the mounting plate 1, a clamping mechanism 4 provided inside the support box 2, and a reinforcement mechanism 3 provided on the right side of the support box 2;
[0027] The reinforcement mechanism 3 includes a long box 31, which is fixedly connected to the right side of the support box 2. A spring 32 is fixedly connected to the right side of the inner wall of the long box 31, and the left end of the spring 32 is fixedly connected to a rectangular plate 33. A pull shaft 34 is fixedly connected to the right side of the rectangular plate 33, and a stopper 35 is rotatably connected to the right end of the pull shaft 34. A fixed block 39 is fixedly connected to one side of the rectangular plate 33, and an internal spline 37 is fixedly connected to the side of the fixed block 39 away from the rectangular plate 33. An external spline 38 is provided on the outside of the clamping mechanism 4, and a support block 36 is fixedly connected to the right side of the long box 31.
[0028] Furthermore, a through hole is provided on a side of the long box 31 away from the mounting plate 1 , and the pull shaft 34 passes through the through hole and moves, so that the pull shaft 34 can move through the through hole.
[0029] Furthermore, the spring 32 is sleeved on the outer wall of the pull shaft 34 , and the rectangular plate 33 is slidably connected to the inner wall of the long box 31 , so that the rectangular plate 33 moves stably to compress the spring 32 .
[0030] Furthermore, a moving opening is opened on one side of the long box 31, and the fixing block 39 passes through the moving opening and moves, so that the fixing block 39 can move through the moving opening.
[0031] Furthermore, the pull shaft 34 passes through the stopper 35 , and the left side of the stopper 35 contacts the right side of the support block 36 , so that the support block 36 can block and limit the stopper 35 . Example 2
[0032] See Figures 1 to 4 On the basis of Example 1, the clamping mechanism 4 is further obtained to include a long screw 41, which is rotatably connected to the left side of the inner wall of the support box 2, and the outer wall of the long screw 41 is threadedly connected to a threaded plate 42, the top of the threaded plate 42 is fixedly connected to a long shaft 43, and the outer wall of the long shaft 43 is fixedly connected to a clamp 44, further ensuring the stability of the injection pump valve core during processing.
[0033] Furthermore, the threaded plate 42 is slidably connected to the inner wall of the support box 2. A long opening is opened on the top of the support box 2. The long shaft 43 passes through the long opening and moves, so that the long shaft 43 can move through the long opening.
[0034] Furthermore, the long screw rod 41 passes through the right side of the support box 2 and rotates, and the right end of the long screw rod 41 is fixedly connected to a hand wheel, so that the long screw rod 41 can be rotated by shaking the hand wheel.
[0035] During actual operation, when this device is used, the injection pump valve core to be processed is first placed on the top of the support box 2, and then the handwheel is turned to drive the long screw 41 to rotate. Since the long screw 41 and the threaded plate 42 are threadedly connected, and the threaded plate 42 can be slid and limited on the inner wall of the support box 2, the rotational motion of the long screw 41 will be converted into the linear motion of the threaded plate 42, so that the threaded plate 42 can drive the clamp 44 to move toward the direction close to the injection pump valve core through the long axis 43, so that the clamp 44 can stably clamp the injection pump valve core, thereby ensuring the stability of the injection pump valve core during the processing, so that it will not easily deviate and shake, achieving good stability, and further improving the quality of processing and production.
[0036] When the clamp 44 has completed the position limiting of the injection pump valve core, the stop block 35 can be rotated so that the stop block 35 can make a circular motion along the axis point of the pull shaft 34, so that the stop block 35 is no longer on the right side of the support block 36. At this time, the spring 32 in the compressed state will push the rectangular plate 33 to move to the left, so that the rectangular plate 33 can drive the inner spline 37 to be clamped to the outer side of the outer spline 38 through the fixed block 39, so that the inner spline 37 is engaged with the outer spline 38. At this time, under the mutual cooperation of the inner spline 37 and the outer spline 38, the long screw 41 cannot rotate, which plays a role in reinforcing the position limiting of the clamp 44, thereby ensuring the stability of the clamp 44 during use, and will not cause loosening or deviation when affected by external factors, thereby enhancing the stability of the injection pump valve core processing.
[0037] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
