[0004] The following defects were found in the above-mentioned issues: In the existing technology for connecting rod alignment, it is usually necessary to fix the connecting rod during the alignment process, and further fix the large end and small end of the connecting rod. However, due to the different specifications and types of connecting rods, the diameters of the large end and small end of the connecting rod are also different. Existing connecting rod alignment devices cannot fix and clamp all connecting rods with different diameter large and small end holes, and different connecting rod alignment devices need to be replaced for fixation. This leads to an increase in the manpower input of operators and a reduction in work efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing link alignment devices, which cannot securely clamp all links when faced with large and small diameter holes, requiring the replacement of different link alignment devices. This increases the manpower required by operators and reduces work efficiency. Therefore, this invention proposes a link alignment and positioning auxiliary device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a linkage correction and positioning auxiliary device, comprising a base plate and a base, wherein a positioning device is provided on one side of the base plate, the positioning device comprising a disc, the disc being fixedly connected to the base plate, four rectangular slots being provided on one side of the disc, and cylinders being slidably connected to the inner walls of the four rectangular slots, a support column being rotatably connected to one side of the disc, a frustum being fixedly connected to one side of the cylinder, a turntable being fixedly connected to one side of the support column, four elliptical holes being provided on one side of the turntable, the inner walls of the elliptical holes being slidably connected to the arc surfaces of the cylinders, a support plate being fixedly connected to the upper surface of the frustum, a rectangular block being fixedly connected to the upper surface of the disc, a first screw being rotatably connected to the interior of the rectangular block, a slider being slidably connected to the upper surface of the disc, the first screw being threadedly connected to the slider, two connecting rods being fixedly connected to one side of the base plate, a rectangular plate being rotatably connected to one end of each of the two connecting rods, a second screw being threadedly connected to one side of the rectangular plate, and a convex platform being fixedly connected to one side of the base plate.

[0007] The effect achieved by the above components is as follows: when the connecting rod needs to be aligned, the large hole end of the connecting rod is fitted onto the four support plates, the first screw is rotated to drive the slider to slide on the disc and drive the turntable to rotate. The rotation of the turntable causes the four support plates to spread outward and abut against the inner wall of the large hole of the connecting rod from the inside to play a fixing role. The small hole end of the connecting rod is fitted onto the convex platform, the rectangular plate is rotated and the two second screws are rotated to press the connecting rod tight.

[0008] Preferably, two handles are fixedly connected to the side of the first screw nut, and the ends of the two handles away from the screw are semi-circular.

[0009] The effect achieved by the above components is that it is more convenient and less strenuous to rotate the first screw by using the grip, and the semi-circular shape of one end of the grip increases the comfort of holding the grip.

[0010] Preferably, two anti-wear pads are fixedly connected to the ends of the two second screws away from the rectangular plate, and the two anti-wear pads can completely cover one end of the screw.

[0011] The effect achieved by the above components is that when the connecting rod is pressed by the second screw, the anti-wear pad can reduce the degree of wear between the second screw and the connecting rod.

[0012] Preferably, both connecting rods are fitted with springs, and the springs are fixedly connected to the rectangular plate and the base plate, respectively.

[0013] The effect achieved by the above components is that when it is necessary to place the connecting rod on the convex platform, the rectangular plate can be rotated to place the connecting rod. After releasing the spring force of the rectangular plate, the rectangular plate can automatically return to its original position, reducing labor costs.

[0014] Preferably, the base has two fixing devices on one side, each of the fixing devices including a connecting plate, both of the connecting plates being fixedly connected to the base, and two limiting plates being fixedly connected to one side of the connecting plate, with a rotating rod rotatably connected to the side of the two limiting plates that are close to each other, and a buckle being fixedly connected to the rotating rod to the arc surface, the buckle being "L" shaped.

[0015] The effect achieved by the above components is that when the entire device needs to be placed on a table, the device can be secured to the table using the clips, thus fixing the entire device to the table.

[0016] Preferably, four rubber pads are fixedly connected to the lower surface of the base, and the four rubber pads are respectively distributed at the four corners of the base.

[0017] The effect achieved by the above components is that when the entire device is placed on a table, the rubber pad increases the friction between the base and the table, preventing the device from tipping over.

[0018] Preferably, a plurality of rubber strips are fixedly connected to the long arm ends of the two buckles, and the plurality of rubber strips are evenly distributed on the buckles.

[0019] The effect achieved by the above components is to increase the friction between the buckle and the table by using rubber strips, thus improving the fixing effect.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, a positioning device is provided to simultaneously position the large-hole end and the small-hole section of the connecting rod when linkage alignment is required. The device performs this function. Specifically, before linkage alignment, the large-hole end of the connecting rod is slowly fitted onto the arc surfaces of the four support plates. Since the connecting rods have different specifications, the diameters of the large-hole end and the small-hole section will also differ. After fitting the large-hole end onto the support plates, the first screw is slowly rotated using a lever. Because the first screw is rotatably connected to the rectangular block, and the rectangular block is fixedly connected to the disc, and the first screw is threadedly connected to the slider, while the slider is slidably connected to the surface of the disc, rotating the first screw causes the slider to slide on the disc. Since the slider is fixedly connected to the turntable, the slider's sliding motion causes the turntable to rotate. At this point, because the turntable has four elliptical holes, and four cylinders are slidably connected in the four elliptical holes, and the four cylinders are slidably connected to the inner walls of the four rectangular slots on the turntable, when the turntable starts to rotate, the four cylinders will be restricted by the elliptical holes and slide outward along the rectangular slots at the same time. The four cylinders and four support plates are fixedly connected by the frustum, so the four support plates will also spread outward with the cylinders until they spread to the large hole end that can tighten the connecting rod from the inside. The first screw will then stop rotating. Then the rectangular plate can be rotated around the connecting rod to fit the small hole section of the connecting rod onto the convex platform. After placement, the rectangular plate is released, and the rectangular plate will rotate back to its original position due to the spring force. Then the two second screws are rotated downward until the connecting rod is pressed tightly. At this point, the entire connecting rod is successfully fixed. Then, the connecting rod is corrected with the help of tools.

[0022] In this invention, a fixing device is provided. In certain situations, the device needs to be aligned on a platform or table. However, during the alignment process, the connecting rod will be subjected to a large force, which can easily cause the device to tip over on the table. To prevent this, a fixing device is designed. The main operating steps are as follows: When the device is placed on the table, to prevent the entire device from tipping over during the alignment process, two fixing devices located on one side of the base can be used to fix the device to the table or other platform. Before fixing, the buckle needs to be rotated in a circle around the rotating rod to rotate it upwards. Then, the device is placed on the table. After placement, since the buckle is fixedly connected to the rotating rod, and the rotating rod is rotatably connected to the two limiting plates, the rotating rod will rotate with the buckle. Then, the buckle is rotated downwards in the same way, so that the long arm end of the buckle is parallel to the lower surface of the table. The rubber strip on the long arm end of the buckle increases the friction between it and the lower surface of the table, while the four rubber pads on the lower surface of the base increase the friction between it and the upper surface of the table. Both of these factors improve the fixing effect. Attached Figure Description

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a connecting rod correction and positioning auxiliary device, including a base plate 1 and a base 2. A positioning device 3 is provided on one side of the base plate 1, and two fixing devices 4 are provided on one side of the base 2.

[0030] The specific setup and function of its positioning device 3 and fixing device 4 will be explained in detail below.

[0031] Reference Figure 2As shown, in this embodiment: the positioning device 3 includes a disc 301, which is fixedly connected to the base plate 1. Four rectangular slots 302 are provided on one side of the disc 301. A cylinder 304 is slidably connected to the inner wall of each of the four rectangular slots 302. A support column 303 is rotatably connected to one side of the disc 301. A frustum 307 is fixedly connected to one side of the cylinder 304. A turntable 305 is fixedly connected to one side of the support column 303. Four elliptical holes 306 are provided on one side of the turntable 305. The inner wall of each elliptical hole 306 is slidably connected to the arc surface of the cylinder 304. A support plate 308 is fixedly connected to the upper surface of the platform 307. A rectangular block 309 is fixedly connected to the upper surface of the disc 301. A first screw 310 is rotatably connected inside the rectangular block 309. A slider 311 is slidably connected to the upper surface of the disc 301. The first screw 310 is threadedly connected to the slider 311. Two connecting rods 313 are fixedly connected to one side of the base plate 1. A rectangular plate 315 is rotatably connected to one end of each connecting rod 313. A second screw 316 is threadedly connected to one side of the rectangular plate 315. A convex platform 317 is fixedly connected to one side of the base plate 1. When connecting rod alignment is required, the large-hole end of the connecting rod is fitted onto the four support plates 308. Rotating the first screw 310 causes the slider 311 to slide on the disc 301, which in turn rotates the turntable 305. The rotation of the turntable 305 causes the four support plates 308 to spread outwards, abutting against the inner wall of the large-hole of the connecting rod from the inside, thus fixing it in place. The small-hole end of the connecting rod is fitted onto the convex platform 317. Rotating the rectangular plate 315 and the two second screws 316 tightens the connecting rod. Two grips 312 are fixedly connected to the side of the nut of the first screw 310. The ends of the two grips 312 away from the screw are semi-circular. Using the grips 312 to rotate the first screw 310 is more convenient and less strenuous. The semi-circular shape of one end of the grip increases the comfort of holding the grip. Two anti-wear pads 318 are fixedly connected to the ends of the two second screws 316 away from the rectangular plate 315, completely covering one end of the screw. When the connecting rod is clamped using the second screw 316, the anti-wear pad 318 reduces the wear between the second screw 316 and the connecting rod. Both connecting rods 313 are fitted with springs 314, which are fixedly connected to the rectangular plate 315 and the base plate 1, respectively. When the connecting rod needs to be placed on the convex platform 317, the rectangular plate 315 can be rotated. After placing the connecting rod, releasing the spring force of the rectangular plate 315 allows the rectangular plate 315 to automatically return to its original position, reducing labor costs.

[0032] Reference Figure 3 , Figure 4 and Figure 5As shown in this embodiment: both fixing devices 4 include connecting plates 41, both connecting plates 41 are fixedly connected to the base 2, and two limiting plates 42 are fixedly connected to one side of the connecting plate 41. A rotating rod 43 is rotatably connected to the side of the two limiting plates 42 that are close to each other. A buckle 44 is fixedly connected to the arc surface of the rotating rod 43. The buckle 44 is L-shaped. When the entire device needs to be placed on a table, the buckle 44 can be used to lock the device to the table, thus fixing the entire device to the table. Four rubber pads 46 are fixedly connected to the lower surface of the base 2, and the four rubber pads 46 are distributed at the four corners of the base 2. When the entire device is placed on the table, the rubber pads 46 can increase the friction between the base 2 and the table, preventing the device from tipping over. Several rubber strips 45 are fixedly connected to the long arm ends of the two buckles 44, and the rubber strips 45 are evenly distributed on the buckles 44. The rubber strips 45 increase the friction between the buckles 44 and the table, making the fixing effect better.

[0033] Working principle: In this utility model, by setting a positioning device 3, when the connecting rod needs to be corrected, the large hole end and the small hole section of the connecting rod need to be positioned simultaneously. This device plays this role. The specific operation of the device is as follows: Before the connecting rod is corrected, the large hole end of the connecting rod can be slowly put onto the arc surface of the four support plates 308. Since the specifications and types of the connecting rod are different, the diameters of the large hole end and the small hole section will also be different. Put the large hole end on the support plate 308. At this time, use the gripping rod 312 to slowly rotate the first screw 310. Since the first screw 310 is rotatably connected to the rectangular block 309, the rectangular block 309 is fixedly connected to the disc 301, and the first screw 310 is threadedly connected to the slider 311, and the slider 311 is slidably connected to the surface of the disc 301, when the first screw 310 is rotated, the first screw 310 will drive the slider 311 to slide on the disc 301. Since the slider 311 and the turntable 305 are fixedly connected, the slider 311 will drive the turntable 305 to rotate during the sliding process. At this time, because the turntable 305 has four elliptical holes 306, and four cylinders 304 are slidably connected in the four elliptical holes 306, and the four cylinders 304 are slidably connected to the inner walls of the four rectangular grooves 302 on the disc 301, when the turntable 305 starts to rotate, the four cylinders 304 will be restricted by the elliptical holes 306 and slide outward along the rectangular grooves 302 simultaneously. The four cylinders 304 and the four support plates 308 are fixedly connected by the frustum 307, so the four support plates 308 will also slide outward along with the cylinders 304. 04. Spread outwards until it reaches the large hole end that can support the connecting rod from the inside. The first screw 310 will then stop rotating. Then, the rectangular plate 315 can be rotated around the connecting rod 313 to fit the small hole section of the connecting rod onto the convex platform 317. After placement, the rectangular plate 315 is released. Due to the elastic force of the spring 314, the rectangular plate 315 will rotate back to its original position. Then, the two second screws 316 are rotated downwards until the connecting rod is pressed. At this point, the entire connecting rod is successfully fixed. Then, the connecting rod is corrected with the help of tools.

[0034] In this utility model, by setting the fixing device 4, in some cases, the device needs to perform the linkage correction work on a platform or table. However, during the correction process, the linkage will be subjected to a large force, which will cause the device to easily tip over on the table. In order to prevent this from happening, the fixing device 4 is designed. Its main operating steps are as follows: when the device is placed on the table, in order to prevent the entire device from tipping over during the correction process, two fixing devices 4 set on one side of the base 2 can be used to fix the device together with the table or other platform. Before fixing, first, the buckle 44 needs to be rotated in a circle around the rotating rod 43 to rotate the buckle 44 upwards. Then, place the device on the table. After it is placed, since the buckle 44 is fixedly connected to the rotating rod 43, and the rotating rod 43 is rotatably connected to the two limiting plates 42, the rotating rod 43 will rotate as the buckle 44 rotates. Then, rotate the buckle 44 downwards in the same way, so that the long arm end of the buckle 44 is parallel to the lower surface of the table. The rubber strip 45 on the long arm end of the buckle 44 increases the friction between it and the lower surface of the table, while the four rubber pads 46 on the lower surface of the base 2 increase the friction between it and the upper surface of the table. Both of these factors make the fixing effect better.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection within a component, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
