Description

Technical Field

[0001] This utility model relates to the field of heddle shaft machining technology, and in particular to an auxiliary positioning mechanism for heddle shaft machining. Background Technology

[0002] The heddle beam is an important component of a water jet loom. Heddle beams are generally long and heavy, but most existing auxiliary positioning devices for heddle beam processing only support the two ends of the heddle beam, which makes the middle part prone to deformation and bending.

[0003] To address the aforementioned problems, those skilled in the art have made improvements to existing technologies. For example, an auxiliary positioning mechanism for machining a heddle shaft, disclosed in CN217193964U, includes a base slidably connected to a slide rail. A telescopic member is provided at the top of the base, and a motor for driving the telescopic member to extend and retract is located inside the base at the bottom of the telescopic member. A support block is disposed on top of the telescopic member and can be tightly pressed against the bottom of the heddle shaft under the action of the telescopic member. Rollers are provided at the contact surface between the support block and the heddle shaft. This mechanism can provide multi-point support for the heddle shaft, preventing deformation and bending. However, the aforementioned device lacks a structure for automatically lifting the heddle shaft, requiring manual handling for loading, resulting in high labor intensity and inconvenience in use.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0023] See Figures 1-4 This utility model provides an auxiliary positioning mechanism for machining a heddle shaft, including a base 1 and a positioning component 2. The base 1 is placed on the ground, and the top surface of the base 1 is provided with a receiving groove. The positioning component 2 is provided in the receiving groove, and upright plates are provided at both ends of the top surface of the base 1.

[0024] See Figures 1-4The positioning component 2 includes a lifting platform 21 and side plates 211. The lifting platform 21 is located in the receiving groove. Side plates 211 are provided at both ends of the top surface of the lifting platform 21. A bottom shaft 22 is rotatably provided at the bottom of the receiving groove. The two ends of the bottom shaft 22 are rotatably connected to the side walls at both ends of the receiving groove. Two first sliders 222 are provided on the bottom shaft 22. The first sliders 222 are slidably connected to the bottom surface of the receiving groove. Two first circulation grooves in opposite directions are provided on the surface of the bottom shaft 22. The two first sliders 222 cooperate with the two first circulation grooves respectively. A first connecting rod 223 is rotatably provided between the first sliders 222 and the lifting platform 21 (i.e., one end of the first connecting rod 223 is rotatably connected to the lifting platform 21, and the other end of the first connecting rod 223 is rotatably connected to the first sliders 222). When the bottom shaft 22 rotates in one direction, it can drive the two first sliders 222 to move synchronously in opposite directions, thereby realizing the reciprocating lifting of the lifting platform 21.

[0025] See Figures 1-4 Each side plate 211 is rotatably equipped with a turntable 23, and each turntable 23 is equipped with a second gear 231. The second gear 231 is concentric with the turntable 23. The turntable 23 has a through hole in the middle for the lifting shaft to pass through. Each upright plate is equipped with a mating hole. Several end shafts 24 are rotatably equipped on the turntable 23. Each end shaft 24 is equipped with a second slider 241. The surface of the end shaft 24 is equipped with a second circulation groove that mates with the second slider 241. Each end shaft 24 is equipped with a clamping member 25 on the side near the center of the turntable 23. Each clamping member 25 is slidably connected to the turntable 23. Each clamping member 25 has a push plate 251 slidably passing through its interior. Each push plate 251 and clamping member 25 is equipped with an elastic element. Each adjacent second slider 241 and push plate 251 is rotatably connected with a second connecting rod 243 (i.e., one end of the second connecting rod 243 is rotatably connected to the push plate 251, and the other end of the second connecting rod 243 is rotatably connected to the second slider 241). Each end shaft 24 is equipped with a third gear 241, and a double-sided gear ring 26 is rotatably provided on the turntable 23. That is, both the inner and outer side walls of the double-sided gear ring 26 are equipped with gear rings, and the gear rings on the inner side wall of the double-sided gear ring 26 mesh with and connect to several third gears 241.

[0026] See Figures 1-4Each of the receiving slots is rotatably connected to a drive shaft 27, and each drive shaft 27 is provided with a fourth gear 272. One of the drive shafts 27 is connected to a drive component 271, which is located on the outer wall of the base 1. A first gear 221 that meshes with the fourth gear 272 is rotatably provided on the bottom shaft 22. Each first gear 221 is provided with a positive ratchet. A positive pawl that can rotate in one direction is rotatably connected to the bottom shaft 22. The bottom shaft 22, the first gear 221 and the positive ratchet are concentric. A central shaft 28 and a top shaft 29 are rotatably mounted on the side walls (i.e., vertical plates) at both ends of the receiving groove. A fifth gear 281 is rotatably mounted on the central shaft 28, and a sixth gear 291 is rotatably mounted on the top shaft 29. The fifth gear 281 can mesh with the outer gear ring of the double-sided gear ring 26, and when the two mesh, the fifth gear 281 is located below the double-sided gear ring 26. The sixth gear 291 can mesh with the second gear 231, and when the two mesh, the sixth gear 291 is located above the second gear 231. Both the fifth gear 281 and the sixth gear 291 are equipped with anti-ratchet wheels. A unidirectional rotatable anti-racket is rotatably connected to both the central shaft 28 and the top shaft 29. The central shaft 28, the fifth gear 281, and the anti-ratchet wheel on the fifth gear 281 are concentric, as are the top shaft 29, the sixth gear 291, and the anti-ratchet wheel on the sixth gear 291.

[0027] See Figures 1-4 Preferably, a drive shaft is rotatably provided inside the receiving groove, and the two ends of the drive shaft are rotatably connected to the two end side walls of the receiving groove respectively. A belt is provided between the drive shaft 27, the middle shaft 28, the top shaft 29 and the drive shaft. The user can also replace the belt drive with a chain drive to ensure good transmission efficiency. The addition of the transmission gear and the cooperation between the transmission gear and the chain are existing technologies, so they will not be described in detail.

[0028] See Figures 1-4 Preferably, the top surface of the lifting platform 21 is provided with several fixed seats 212, and the top surface of each fixed seat 212 is slidably provided with a support 213. An elastic element is provided between the support 213 and the fixed seat 212, and the support 213 can provide auxiliary support for the lifting shaft.

[0029] See Figures 1-4 Preferably, the drive unit 271 is a rotary motor that can provide sufficient power.

[0030] In the implementation of this utility model: the height of the base 1 is set so that when the lifting platform 21 is at the lowest point of its movement range, the height of the through hole on the turntable 23 is the same as the height of the lifting shaft on the transfer device (in factories, trolleys are often used to transfer the lifting shaft; the base 1 should be adjusted according to the height of the trolley, or the height of the trolley or other storage and transfer device should be adjusted according to the height of the base 1). The user pushes the lifting shaft so that it passes through the two through holes. At this time, the lifting platform 21 is at the lowest point of its movement range. At this time, the fifth gear 281 meshes with the double-sided gear ring 26, and the drive component 271 rotates forward. At this time, the positive ratchet does not engage with the positive pawl, and the negative ratchet engages with the negative pawl, that is, the bottom shaft 22 does not rotate, and the fifth gear 281 and the sixth gear 291 rotate. Due to the sixth gear... At this time, the wheel 291 and the first gear 221 are not meshed. Therefore, the fifth gear 281 drives the double-sided gear ring 26 to rotate, causing several end shafts 24 to rotate synchronously. This causes several clamping parts 25 to move in the opposite direction to the heddle shaft and clamp the heddle shaft. Then, the drive part 271 rotates forward. At this time, the positive ratchet engages with the positive pawl, while the negative ratchet does not engage with the negative pawl. The bottom shaft 22 rotates, causing the two first sliders 222 to move away from each other. The lifting platform 21 rises. When the lifting platform 21 rises to the highest point of its movement range, the sixth gear 291 meshes with the first gear 221. At this time, the processing device processes the heddle shaft. When it is necessary to rotate the heddle shaft, the drive part 271 reverses, causing the sixth gear 291 to drive the first gear 221 to rotate, which in turn causes the turntable 23 to drive the heddle shaft to rotate.

[0031] This utility model provides an auxiliary positioning mechanism for machining heald shafts, which has the following advantages:

[0032] 1. By setting up a lifting platform, the lifting shaft can be automatically raised and lowered, reducing the labor intensity of users and improving processing efficiency.

[0033] 2. By setting up a turntable and several clamping components, the lifting shaft can be automatically positioned and driven to rotate automatically, which facilitates the processing equipment to process the lifting shaft and improves processing efficiency.

[0034] 3. This device uses a single power source to lift, clamp, and rotate the lifting shaft, reducing operating costs.

[0035] In summary, the beneficial effects of this utility model are: it can automatically clamp, lift, and rotate the lifting shaft, reducing the labor intensity of users, improving processing efficiency, and reducing usage costs.

[0036] Of course, there may be many other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
