Abstract
Description
Technical Field
[0001] Embodiments of this disclosure relate to the field of machine tool technology, and more specifically, to a machine tool for processing ratchet wrenches. Background Technology
[0002] A ratchet wrench is a manual screw tightening and loosening tool. It comes in single-headed and double-headed versions with various sizes and adjustable handles (for fixed holes). It consists of main and secondary ratchet sleeves of different sizes connected by a hinge key. Sometimes, ratchet wrenches require printing or marking on the back, which necessitates the use of a machining tool.
[0003] Traditional machine tools for processing ratchet wrenches have the following shortcomings: In traditional use, the ratchet wrench is typically placed directly on a push plate, which is then pushed under the printing plate. A cylinder or hydraulic cylinder then drives the printing plate to press the ratchet wrench against the printing plate. However, when positioning the ratchet wrench, the groove is usually placed directly on top of a positioning block. Since the size of the groove in each ratchet wrench may vary slightly, manual placement during positioning can cause slight displacement or rotation of the ratchet wrench, resulting in misaligned printing and affecting the appearance. Therefore, improvements are needed. Utility Model Content

Therefore, they should not be construed as limitations on this disclosure.
[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0032] like Figures 1-7 The diagram illustrates a machine tool for processing a ratchet wrench according to an embodiment of this disclosure. It includes a base 1, a displacement mechanism 2 disposed above the base 1, a positioning mechanism 3 disposed inside the displacement mechanism 2, a ratchet wrench 5 placed above the positioning mechanism 3, and a printing mechanism 4 disposed above the base 1. The printing mechanism 4 includes a rectangular plate 41 welded to the base 1, round rods 42 welded to the top of both ends of the rectangular plate 41, a top plate 43 welded above the round rods 42, and a hydraulic cylinder 44 fixedly mounted above the top plate 43. The outer side of 42 is movably sleeved with a long plate 45 located below the top plate 43. The output end of the hydraulic cylinder 44 is fixedly connected to the top of the long plate 45. A calibration component 8 is provided below the long plate 45. The calibration component 8 includes a protruding plate 81 welded below the long plate 45. Movable grooves 82 are opened inside both ends of the protruding plate 81. A movable plate 83 is slidably installed inside the movable groove 82. A vertical plate 84 extending to the bottom of the protruding plate 81 is welded below the movable plate 83. A telescopic spring 85 is elastically installed between the inner side of the movable plate 83 and the inner side of the movable groove 82.
[0033] In some examples, firstly, the push rod 34 is pulled, moving the push plate 31 to the outermost end of the long groove 23. At this time, the ratchet wrench 5 is placed directly above the push plate 31, so that the groove 7 is inserted above the positioning block 32. Then, the tail end of the ratchet wrench 5 is placed inside the limit rod 33, and the push rod 34 is pushed, moving the push plate 31 to the front end of the long groove 23. The moving component 6 is attracted and fixed by the magnet 24 at the front end of the long groove 23. Then, the hydraulic cylinder 44 is activated, causing the hydraulic cylinder 44 to drive the long plate 45 downward, so that... The long plate 45 drives the calibration component 8 to move downwards. The vertical plate 84 will first contact the front end of the ratchet wrench 5, so that the arc surface of the vertical plate 84 presses the calibration component 8, thereby pushing the calibration component 8 to perform calibration. At this time, the convex plate 81 continues to move downwards, so that the vertical plate 84 retracts into the interior of the movable groove 82 and presses the telescopic spring 85, causing the telescopic spring 85 to deform. After the vertical plate 84 is completely retracted into the interior of the movable groove 82, the printing block 86 presses the back of the front end of the ratchet wrench 5, thereby completing the printing operation.
[0034] By inserting the groove 7 above the positioning block 32, and then placing the tail end of the ratchet wrench 5 between the inner sides of the limiting rod 33 for auxiliary positioning, the hydraulic cylinder 44 drives the convex plate 81 to move downward, so that the vertical plate 84 contacts the ratchet wrench 5 and pushes the position of the ratchet wrench 5 for calibration. Then the convex plate 81 continues to move downward and prints the back of the ratchet wrench 5 through the printing block 86. Compared with the traditional machine tool for processing ratchet wrenches, this machine tool for processing ratchet wrenches uses the limiting rod 33 to assist in positioning the tail end of the ratchet wrench 5, and at the same time uses the vertical plate 84 to calibrate the position of the ratchet wrench 5, which improves the printing effect of the printing block 86 on the ratchet wrench 5 and makes it easier to use.
[0035] like Figures 1-7 As shown, a machine tool for processing ratchet wrenches is illustrated in another embodiment of the present disclosure. The displacement mechanism 2 includes side plates 21 welded to both sides above the base 1. A long groove 23 is provided above the base 1 between the inner sides of the two side plates 21. The positioning mechanism 3 includes a push plate 31 slidably installed inside the long groove 23. A moving component 6 is provided below both ends of the push plate 31. The moving component 6 includes an iron plate 61 welded below the push plate 31. A circular groove 62 is provided below both ends of the iron plate 61. A circular block 63 is welded to both ends of the circular groove 62. A circular shaft 64 is welded to the inner side of the circular block 63. A roller 65 is rotatably installed on the outer side of the circular shaft 64.
[0036] In some examples, when the push rod 34 is pushed or pulled, the roller 65 rotates inside the long groove 23, thereby assisting the push plate 31 to move back and forth inside the long groove 23, reducing the friction between the push plate 31 and the long groove 23, and making it easier for the operator to use.
[0037] like Figures 3-5 As shown, a machine tool for processing a ratchet wrench is shown in another embodiment of the present disclosure. A positioning block 32 is welded above the front end of the push plate 31, and a limit rod 33 is uniformly welded above the push plate 31. A groove 7 is provided on the inner side of the front end of the ratchet wrench 5, and the groove 7 is placed above the long groove 23.
[0038] In some examples, the front end of the ratchet wrench 5 is positioned by the positioning block 32, and the rear end of the ratchet wrench 5 is assisted in positioning by the limiting rod 33.
[0039] like Figures 1-4 As shown, a machine tool for processing ratchet wrenches is shown in another embodiment of the present disclosure. A push rod 34 is fixedly installed above the bottom end of the push plate 31, magnets 24 are fixedly installed at both ends of the long groove 23, and square plates 22 are welded between the inner front ends of the two side plates 21.
[0040] In some examples, pulling or pushing the push rod 34 causes the push plate 31 to be attracted to the iron plate 61 by the magnet 24 when it is pushed to the front or rear end.
[0041] like Figure 7 As shown, it illustrates a machine tool for processing ratchet wrenches in another embodiment of the present disclosure, wherein the inner side of the vertical plate 84 is designed with an arc surface, and the top width of the vertical plate 84 is smaller than the bottom width.
[0042] In some examples, when the vertical plate 84 moves downward and contacts the front end of the ratchet wrench 5, the inner side of the vertical plate 84 pushes the ratchet wrench 5 to calibrate, so that the ratchet wrench 5 is positioned just between the inner sides of the vertical plate 84.
[0043] like Figures 1-7 As shown, it illustrates a machine tool for processing a ratchet wrench in another embodiment of the present disclosure, wherein a printing block 86 protrudes below the convex plate 81, and the lower part of the printing block 86 corresponds vertically to the upper part of the front end of the ratchet wrench 5.
[0044] In some examples, after the ratchet wrench 5 moves below the convex plate 81 and is calibrated, the printing block 86 moves downward to print on the ratchet wrench 5.
[0045] like Figure 3 As shown, it illustrates a machine tool for processing ratchet wrenches in another embodiment of the present disclosure, wherein there are two sets of limit rods 33, which are symmetrically installed above the push plate 31.
[0046] In some examples, by setting two sets of limit rods 33, the rear end of the ratchet wrench 5 is prevented from deviating by a large range, and the rear end of the ratchet wrench 5 is assisted in positioning by the two sets of limit rods 33.
[0047] like Figure 3 As shown, it illustrates a machine tool for processing ratchet wrenches in another embodiment of the present disclosure, wherein there are two limit rods 33 in each group, and the two limit rods 33 are symmetrically installed above the push plate 31.
[0048] In some examples, the rear end of the ratchet wrench 5 is laterally limited by two limiting rods 33, which makes it easier for the operator to place the rear end of the ratchet wrench 5 between the inner sides of the limiting rods 33.
[0049] like Figure 4 As shown, it illustrates a machine tool for processing ratchet wrenches in another embodiment of the present disclosure, wherein there are two sets of moving components 6, which are welded to the lower ends of the push plate 31 and are installed symmetrically.
[0050] In some examples, the friction between the push plate 31 and the long groove 23 is reduced by the movable component 6, while the symmetrically installed movable component 6 facilitates the load-bearing of the push plate 31 and makes it easy to use.
[0051] like Figures 3-5 As shown, it illustrates a machine tool for processing a ratchet wrench in another embodiment of the present disclosure, wherein the distance between the two limit rods 33 is adapted to the width of the ratchet wrench 5, and the length of the push plate 31 is greater than the length of the ratchet wrench 5.
[0052] In some examples, the ratchet wrench 5 is placed directly between the inner sides of the limit rod 33, so that the ratchet wrench 5 is positioned above the push plate 31, thereby pushing the ratchet wrench 5 below the printing mechanism 4 for processing via the push plate 31.
[0053] Working principle and usage process of this utility model:
[0054] First, pull the push rod 34 to move the push plate 31 to the outermost end of the long groove 23. At this time, place the ratchet wrench 5 directly above the push plate 31 so that the groove 7 is inserted above the positioning block 32. Then, place the tail end of the ratchet wrench 5 inside the limit rod 33 and push the push rod 34 to push the push plate 31 to the front end of the long groove 23. The moving component 6 is attracted and fixed by the magnet 24 at the front end of the long groove 23. Then, start the hydraulic cylinder 44 to drive the long plate 45 downward, so that the long plate 45... The calibration component 8 moves downward, and the vertical plate 84 first contacts the front end of the ratchet wrench 5, causing the arc surface of the vertical plate 84 to press against the calibration component 8, thereby pushing the calibration component 8 to perform calibration. At this time, the convex plate 81 continues to move downward, causing the vertical plate 84 to retract into the interior of the movable groove 82 and press against the telescopic spring 85, causing the telescopic spring 85 to deform. After the vertical plate 84 is completely retracted into the interior of the movable groove 82, the printing block 86 presses against the back of the front end of the ratchet wrench 5, thereby completing the printing operation.
