Description
Technical Field
[0001] The invention relates to the technical field of textile machinery, in particular to an upper pin adjusting platform. Background Art
[0002] In the textile industry, the upper pin (referred to as the upper pin) of the spinning machine drafting is in the shape of a double-linked blade. The upper and lower pins can support the rubber ring jaws through the spring self-adjusting jaw pressure on the upper pin, and have a certain relationship with the speed distribution of the key fibers in the roller drafting area and the yarn evenness. Its elastic jaw part supports the upper rubber ring in a certain working position, and swings up and down within a certain range with the middle iron roller shaft core. Through the elastic action of the leaf spring, a certain starting pressure is applied to the rubber ring curved surface at the jaws to avoid plastic deformation during repeated up and down swings. During the drafting process, the upper pin of the jaws can absorb the vibration of the rubber ring during rotation, stabilize the rotation speed of the rubber ring, and ensure the stable movement of the fiber.
[0003] The quality of the upper pin is the premise to ensure the quality of the yarn. In production, the upper pin is required to maintain balance and symmetry on both sides, the working surface of the rubber ring is smooth without burrs and scars; the rubber ring baffle is not skewed or damaged, and has a certain hardness and toughness; the front edge of the upper pin and the core of the middle iron roller swing within a certain range and always remain parallel; after assembly with the rubber ring and the middle iron rod, the rubber ring must be flexible and the tension is stable; the leaf spring must have sufficient elasticity and maintain the minimum elastic difference. In this way, it can be ensured that the upper pin and the fixed curved lower pin form a pair of elastic rubber ring jaws with the upper and lower rubber rings, so that the fiber forms a uniform motion between the upper and lower rubber rings, and basically can change speed uniformly after reaching the speed change point, which is conducive to improving the uniformity of the yarn.
[0004] The current problem is that most of the existing upper pins are made of metal iron plates, which are made of steel plate stamping parts through spot welding, are non-sticky, and have excellent anti-static properties. However, after long-term use, the upper pins made of iron plates are prone to deformation, and the bottom edge is unbalanced, which can easily cause the rubber ring working section to be too loose, too tight, or concave.
[0005] When the working surface of the rubber ring is too loose, undesirable phenomena such as rubber ring arching and slipping will occur; when it is too tight, the rubber ring linear speed will be different, and the rubber ring will be damaged and the upper pin will fluctuate, which will seriously affect the effective grip of the elastic jaws on the fiber, and the effect of the middle part of the rubber ring on controlling the whisker fiber will drop sharply, the elastic gripping force will be uneven, resulting in unstable distribution of friction force in the drafting zone, loss of control over the movement of floating fibers, thereby deteriorating the yarn dryness and significantly increasing the number of yarn defects.
[0006] To address this drawback, it is necessary to regularly inspect the accuracy of the upper pins and adjust the accuracy of the upper pins with deformation defects. However, there is currently no dedicated device or equipment available in this field. Summary of the invention
[0007] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an upper pin adjustment platform, which can realize the detection and correction of various angles, directions and deformation points of the upper pin.
[0008] Its specific structure is described as follows: an upper pin adjustment platform, which includes a base plate; the base plate includes at least one or more of an upper pin bottom edge pass-stop combination, an upper pin bottom edge deformation detection platform, an overall horizontal detection platform, an adjustment positioning axis, a deformation adjustment positioning groove, and an upper pin bottom edge accuracy inspection platform.
[0009] The upper pin bottom edge pass-stop combination comprises two correspondingly arranged upper pin passing platforms and an upper pin stopping platform, the upper pin passing platform comprises a pass-stop base, a support base is arranged on the pass-stop base, a support shaft is fixed through the support base, and the upper pin clamping ring is fixed on the support shaft; a positioning baffle plate which can be adjusted to a distance from the upper pin bottom edge is arranged near the upper pin bottom edge; the upper pin stopping platform has the same structure as the upper pin passing platform, and whether it passes or not is achieved by adjusting the relative position of the positioning baffle plate and the upper pin bottom edge.
[0010] The upper pin bottom edge deformation detection platform includes a bottom platform, and an upper pin clamp ring positioning seat is arranged on the front side of the bottom platform. After the upper pin clamp ring is positioned and fixed, the upper pin bottom edge is overlapped on the base platform, and the gap detection ruler is inserted under the upper pin bottom edge to realize gap detection.
[0011] The overall level detection platform is a level detection platform, which confirms whether the bottom surface of the upper pin is level by placing the upper pin upright.
[0012] The adjustment and positioning shaft is fixed horizontally on the bottom plate. The adjustment and positioning shaft is a stepped shaft with thick ends and thin middle part. The height from the middle outer diameter to the bottom plate is smaller than the radius of the upper pin clamp ring. The bottom plate in the fixing area of the adjustment and positioning shaft is set horizontally.
[0013] The width of the deformation adjustment positioning groove matches the thickness of the upper pin, and the upper pin can be adjusted by turning after being inserted.
[0014] The upper pin bottom edge accuracy inspection table includes a bottom track groove, a fixing part that can slide laterally is arranged in the bottom track groove, a transverse axis is arranged on the fixing part, a vertical support column is arranged on the rear side of the transverse axis, after the upper pin clamping ring is fixed to the transverse axis, the bottom edge of the upper pin is overlapped on the vertical support column to realize the fixation of the upper pin; a micrometer fixing frame is arranged near the bottom track groove to realize the fixation of the micrometer.
[0015] The bottom track groove includes a bottom plate, a vertical fixed edge is arranged on the bottom plate, and a protrusion is arranged on the vertical fixed edge toward the middle of the bottom plate. When the vertical fixed edge is fixed to the bottom plate, a guide groove can be formed on the upper part of the bottom plate to realize vertical constraint on the fixed part.
[0016] The present invention has the following beneficial effects: Through the above design, the present invention combines multiple structures. The bottom plate includes a through-stop combination for the bottom edge of the upper pin. By the cooperation of the passing platform of the upper pin and the blocking platform of the upper pin, the inspection of the distance dimension between the bottom edge of the upper pin and the snap ring of the upper pin can be realized. The deformation detection platform for the bottom edge of the upper pin and a feeler gauge can be used to detect the deformation amount of the bottom edge of the upper pin, and whether it is horizontal when the snap ring of the upper pin and the bottom edge of the upper pin land simultaneously can be tested on the overall horizontal detection platform. Furthermore, after the top surface of the snap ring of the upper pin is clamped by adjusting the positioning shaft, the adjustment of the bottom edge of the upper pin can be realized by knocking the back of the upper pin with an external rubber hammer. After the position of the snap ring of the upper pin is inserted into the deformation adjustment positioning groove, the adjustment can be realized by pulling, so as to realize the adjustment of the area of the snap ring of the upper pin. After the accuracy inspection and adjustment of each point of the upper pin above are carried out, the bottom edge of the upper pin can be measured by dial indicator on the accuracy inspection table for the bottom edge of the upper pin, so as to inspect whether the bottom edge of the upper pin and the back of the upper pin reach the overall adjustment accuracy.
[0017] Through the above structural settings, this device is easy to manufacture and form, convenient to use, low in cost, and can be formed by ordinary machining methods, and is suitable for popularization in the textile field. BRIEF DESCRIPTION OF THE DRAWINGS

The front end of the upper pin is the upper pin snap ring 83, and the front end of the upper pin snap ring 83 is provided with a connecting part 84 of the upper pin snap ring. The most easily deformed parts of such an upper pin are: the upper pin snap ring 83, the connecting part between the upper pin snap ring 83 and the connecting part 84 of the upper pin snap ring; the connecting part between the upper pin snap ring 83 and the back 82 of the upper pin and the bottom edge 81 of the upper pin.
[0028] An upper pin adjustment table includes a bottom plate 1; on the bottom plate 1, there are a through-stop combination 2 of the bottom edge of the upper pin, a deformation detection platform 3 for the bottom edge of the upper pin, an overall horizontal detection platform 4, an adjustment positioning shaft 5, a deformation adjustment positioning groove 6, and an accuracy inspection table 7 for the bottom edge of the upper pin. Through the above structural settings, the accuracy inspection and processing of the upper pin can be realized locally and as a whole.
[0029] As Figure 1 shown, the through-stop combination 2 of the bottom edge of the upper pin includes two correspondingly arranged upper pin passing platforms 22 and upper pin blocking platforms 21. The structures of the upper pin passing platform 22 and the upper pin blocking platform 21 are the same. The following takes the upper pin passing platform 22 as an example for explanation:
[0030] The upper pin passing platform 22 includes a stop base 210 with a semicircular ring structure, the stop base 210 is fixed on the bottom plate, and two front and rear support seats 211 are provided on the stop base 210, and a support shaft 23 is fixed through the two support seats 211, and the lower part of the support shaft is an avoidance groove 212, and the upper pin clamping ring 83 is fixed on the support shaft 23; a positioning baffle 214 that can be adjusted to a distance from the upper pin bottom edge 81 is provided near the upper pin bottom edge 81, and the positioning baffle 214 is fixed on the positioning base 213, and the positioning base 213 and the stop base 210 are integrated; through this structural setting, when in use, the upper pin blocking platform 21 has the same structure as the upper pin passing platform 22, and the relative position of the positioning baffle 214 on the positioning base 213 is adjusted to realize the relative position of the bottom edge of the upper pin of the positioning baffle 214 to realize whether it passes or not, such as Figure 4 As shown, whether the bottom edge of the upper pin is deformed is verified by testing whether the upper pin can pass smoothly when swinging.
[0031] The upper pin bottom edge deformation detection platform 3 comprises a bottom platform 31 of a step structure, two upper pin snap ring positioning seats 32 are arranged on the front side of the bottom platform 31, and a positioning shaft 34 is mounted on the two upper pin snap ring positioning seats 32, and the lower part of the positioning shaft 34 is an avoidance gap 35, and a pressing plate I 33 is arranged on the top of each upper pin snap ring positioning seat 32 to press and fix the positioning shaft 34; through the above structural setting, as Figure 5 As shown, after the upper pin clamping ring 83 is positioned and fixed, the upper pin bottom edge 81 overlaps the higher position of the base platform 31, and a feeler gauge 9 is inserted under the upper pin bottom edge 81 to realize gap detection, and correction and knocking can also be performed with a rubber hammer.
[0032] An overall horizontal detection platform 4 is arranged on the front side of the upper pin bottom edge deformation detection platform 3. The top of the overall horizontal detection platform 4 includes a horizontal detection platform 41. The height of the horizontal detection platform 41 is set to be higher than the upper pin bottom edge pass-stop combination 2. After placing the upper pin on the overall horizontal detection platform 4, the operator can see straight ahead to observe whether the upper pin clamping ring connecting part 84 and the upper pin bottom edge 81 are level when they fall to the ground at the same time.
