Description

Technical Field

[0001] This utility model relates to the field of gauze heddle frame application technology, and in particular to a positioning tool for splicing and processing gauze heddle frames. Background Technology

[0002] The leno heald frame is a key component in textile machinery, primarily used to guide warp yarns to form a specific leno weave, playing an indispensable role in the weaving process. The leno heald frame is typically assembled from multiple beams and frame panels. The precision and stability of this assembly directly affect the quality of the subsequent textile products; therefore, specialized positioning fixtures are required to fix and limit its movement during the assembly process.

[0003] In the existing process of splicing gauze heald frames, traditional positioning fixtures have many technical problems: on the one hand, the spacing adjustment structure of most fixtures is not reasonably designed and cannot flexibly adapt to the beam spacing requirements of gauze heald frames of different specifications, resulting in poor versatility; on the other hand, the clamping stability of the positioning mechanism is insufficient, and the heald frame is prone to displacement or shaking during splicing operations, which leads to a decrease in splicing accuracy and affects the product qualification rate. Therefore, this utility model proposes a positioning fixture for splicing gauze heald frames. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a positioning fixture for splicing and processing gauze heald frames, so as to solve the problems of insufficient positioning accuracy, poor stability and inability to adapt to different specifications of heald frames in the existing gauze heald frame splicing process.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a positioning fixture for splicing and processing of gauze heddles is provided, including a frame, a base plate is bolted to the top of the frame, and an adjustment mechanism is installed on the top of the base plate to adjust the distance between the two crossbeams of the gauze heddles. The top bolt of the adjustment mechanism is connected to multiple positioning mechanisms to clamp and fix the gauze heddles that need to be spliced, ensuring stability during splicing and installation.

[0006] The present invention is further configured such that the bottom of each frame is fixedly connected with an anti-slip foot.

[0007] Through the above technical solution, the anti-slip platform is made of rubber material with a high coefficient of friction. The end face that contacts the ground is provided with anti-slip texture, which can increase the friction between the tooling and the ground, effectively prevent the tooling from shifting or shaking due to force during the splicing of the heddles and frames. At the same time, it can buffer the vibration generated during the processing, providing a stable support foundation for the entire splicing operation.

[0008] The present invention is further configured such that: the adjustment mechanism includes a bidirectional adjustment screw rotatably connected to the top of the substrate via a bearing seat; a handwheel is fixedly connected to one end of the bidirectional adjustment screw; adjustment plates are symmetrically threaded to the outer wall of the bidirectional adjustment screw near both ends; the bottoms of the two adjustment plates are slidably connected to guide rails via sliding blocks; and both sets of guide rails are bolted to the top of the substrate.

[0009] Through the above technical solution, the two ends of the bidirectional adjusting screw are provided with threaded structures with opposite directions of rotation. When the handwheel is turned, the bidirectional adjusting screw can be driven to rotate around the bearing seat. Since the adjusting plate is threadedly engaged with the bidirectional adjusting screw through the threaded sleeve at the bottom, and the adjusting plate is slidably connected to the guide rail through the slide block, the guide rail limits the movement direction of the adjusting plate, so that the two adjusting plates can move in opposite directions along the guide rail, thereby realizing the precise adjustment of the distance between the two adjusting plates to adapt to the beam spacing requirements of different specifications of gauze heald frames.

[0010] The present invention is further configured such that: a limit block is fixedly connected to the other end of the bidirectional adjusting screw, and a threaded sleeve is fixedly connected to the bottom center of each of the two adjusting plates, and the threaded sleeve is threadedly connected to the bidirectional adjusting screw.

[0011] Through the above technical solution, the limiting block is made of metal and fixed to the end of the bidirectional adjusting screw by welding. It can limit the movement stroke of the adjusting plate and prevent the adjusting plate from disengaging from the bidirectional adjusting screw due to excessive movement during the adjustment process, thus ensuring the operational safety of the adjusting mechanism. The threaded sleeve at the bottom of the adjusting plate matches the thread precision of the bidirectional adjusting screw. Through thread meshing transmission, the rotational motion of the handwheel can be converted into the linear motion of the adjusting plate, ensuring the smoothness of the adjustment process and the accuracy of the spacing adjustment.

[0012] The present invention is further configured such that: the positioning mechanism includes a mounting bracket installed on the top of the adjusting plate, a positioning cylinder is bolted to the mounting bracket, a pressing block is bolted to the driving end of the positioning cylinder, two tracks are slidably connected to the bottom of the pressing block, and a positioning block is bolted to the end of the two tracks away from the pressing block.

[0013] Through the above technical solution, the mounting frame provides stable mounting support for the positioning cylinder. The positioning cylinder, as a power source, can drive the piston rod to perform telescopic movements after compressed air is introduced, thereby driving the extrusion block to move linearly along the track. The track guides and limits the movement direction of the extrusion block, ensuring that the extrusion block can move accurately toward the positioning block. Through the cooperation between the extrusion block and the positioning block, the gauze heald frame is clamped and fixed, providing a stable positioning effect for splicing processing.

[0014] The present invention is further configured such that the two tracks and the positioning block are integrally fixed on the top of the adjusting plate by bolts.

[0015] The above technical solution, which uses bolts for integrated fixing, can ensure the connection strength and coaxiality between the track, positioning block and adjusting plate, avoid relative displacement under clamping force, and ensure the overall structural stability of the positioning mechanism. At the same time, it facilitates the disassembly, maintenance or replacement of the track or positioning block in the later stage, and improves the practicality and service life of the tooling.

[0016] The present invention is further configured such that the opposing surfaces of the extrusion block and the positioning block are both provided with inclined surfaces.

[0017] Through the above technical solution, the beveled surface on the opposite side can be adapted to the frame structure of the gauze heddle frame, increasing the contact area between the extrusion block and the positioning block and the gauze heddle frame, and improving the stability of clamping; at the same time, the beveled surface structure can form a guiding effect, making it easy for the gauze heddle frame to be quickly placed into the clamping area, and can automatically calibrate the position of the gauze heddle frame during the clamping process to ensure positioning accuracy and avoid affecting the splicing quality due to the clamping position offset.

[0018] The beneficial effects of this utility model are as follows: 1. The positioning fixture for splicing and processing of gauze heddles proposed in this utility model is designed with a bidirectional adjusting screw and guide rail, which can flexibly adjust the distance between the two adjusting plates, and can adapt to the beam spacing requirements of gauze heddles of different specifications, significantly improving the versatility and applicability of the fixture. 2. The positioning fixture for splicing and processing of gauze heald frames proposed in this utility model uses a positioning cylinder of the positioning mechanism to drive the extrusion block and the positioning block to cooperate and clamp, and the opposing surfaces of the two are provided with inclined surfaces, which not only ensures the stability of clamping, but also achieves accurate positioning of the heald frame, effectively improving the accuracy of splicing and processing of gauze heald frames and the product qualification rate.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] like Figure 1 and Figure 2 As shown, a positioning fixture for splicing and processing gauze heddles includes a frame 1. The bottom of the frame 1 is fixedly connected to anti-slip feet. The anti-slip feet are made of rubber with a high coefficient of friction. The end face that contacts the ground is provided with anti-slip texture, which can increase the friction between the fixture and the ground, effectively prevent the fixture from shifting or shaking due to force during the splicing and processing of gauze heddles, and at the same time buffer the vibration generated during the processing, providing a stable support foundation for the entire splicing operation. The top of the frame 1 is bolted to a base plate 2.

[0023] like Figures 3-5 As shown, an adjustment mechanism 3 is installed on the top of the base plate 2 to adjust the distance between the two crossbeams of the heald frame. The adjustment mechanism 3 includes a bidirectional adjustment screw 31 rotatably connected to the top of the base plate 2 via a bearing seat. A handwheel 32 is fixedly connected to one end of the bidirectional adjustment screw 31. Adjustment plates 33 are symmetrically threaded to the outer wall of the bidirectional adjustment screw 31 near both ends. The bottom of the two adjustment plates 33 are slidably connected to guide rails 34 via sliding blocks, and both sets of guide rails 34 are bolted to the top of the base plate 2. The two bidirectional adjustment screws 31... The end is provided with a threaded structure with opposite rotation direction. When the handwheel 32 is turned, the bidirectional adjusting screw 31 can be driven to rotate around the bearing seat. Since the adjusting plate 33 is threadedly engaged with the bidirectional adjusting screw 31 through the threaded sleeve at the bottom, and the adjusting plate 33 is slidably connected to the guide rail 34 through the slide, the guide rail 34 limits the movement direction of the adjusting plate 33, so that the two adjusting plates 33 can make linear movements in opposite directions along the guide rail 34, thereby realizing the precise adjustment of the distance between the two adjusting plates 33 to adapt to the beam spacing requirements of different specifications of gauze heald frames; The other end of the bidirectional adjusting screw 31 is fixedly connected to a limit block. Threaded sleeves are fixedly connected to the center of the bottom of both adjusting plates 33, and are threadedly fitted onto the bidirectional adjusting screw 31 through these sleeves. The limit block is made of metal and is fixed to the end of the bidirectional adjusting screw 31 by welding. This limits the travel of the adjusting plates 33, preventing them from detaching from the bidirectional adjusting screw 31 due to excessive movement during adjustment, thus ensuring the operational safety of the adjusting mechanism 3. The threaded sleeve at the bottom of the adjusting plate 33 matches the thread precision of the bidirectional adjusting screw 31. Through threaded engagement, the rotational motion of the handwheel 32 can be converted into the linear motion of the adjusting plate 33, ensuring the smoothness of the adjustment process and the accuracy of the spacing adjustment.

[0024] like Figure 6 As shown, the top of the adjusting mechanism 3 is bolted with multiple positioning mechanisms 4 to clamp and fix the heald frames to be spliced, ensuring stability during splicing and installation. The positioning mechanism 4 includes a mounting bracket 41 mounted on the top of the adjusting plate 33. A positioning cylinder 42 is bolted to the mounting bracket 41. A pressing block 43 is bolted to the drive end of the positioning cylinder 42. Two rails 44 are slidably connected to the bottom of the pressing block 43. The two rails 44 and the positioning block 45 are integrally fixed to the top of the adjusting plate 33 by bolts. This integral bolting method ensures the connection strength and coaxiality between the rails 44, the positioning block 45, and the adjusting plate 33, preventing relative displacement under clamping force and ensuring the stability of the positioning mechanism 4. The overall structural stability is ensured; at the same time, it facilitates the disassembly, maintenance, or replacement of the track 44 or positioning block 45 in the later stages, improving the practicality and service life of the tooling. The two tracks 44 are bolted to the positioning block 45 at the ends away from the extrusion block 43. The mounting bracket 41 provides stable installation support for the positioning cylinder 42. The positioning cylinder 42 serves as a power source. After compressed air is introduced, it can drive the piston rod to perform telescopic movement, thereby driving the extrusion block 43 to move linearly along the track 44. The track 44 guides and limits the movement direction of the extrusion block 43, ensuring that the extrusion block 43 can move accurately toward the positioning block 45. Through the cooperation of the extrusion block 43 and the positioning block 45, the clamping and fixing of the heddle frame is achieved, providing a stable positioning effect for splicing processing. Both the pressing block 43 and the positioning block 45 have beveled surfaces on their opposite sides. The beveled surfaces can adapt to the frame structure of the heddle frame, increasing the contact area between the pressing block 43 and the positioning block 45 and the heddle frame, and improving the stability of clamping. At the same time, the beveled surface structure can form a guiding function, making it easy for the heddle frame to be quickly placed into the clamping area. During the clamping process, the position of the heddle frame can be automatically calibrated to ensure positioning accuracy and avoid affecting the splicing quality due to the clamping position deviation.

[0025] In use, this invention first involves rotating the handwheel 32 according to the required beam spacing of the gauze heddle frames to be spliced. This rotates the bidirectional adjusting screw 31, causing the two adjusting plates 33 to move in opposite directions along the guide rail 34 to adjust to the appropriate spacing. Then, the frame of the gauze heddle frame is placed between the positioning block 45 and the pressing block 43. The positioning cylinder 42 is then activated, driving the pressing block 43 to move along the track 44 toward the positioning block 45. The inclined surfaces of the pressing block 43 and the positioning block 45 work together to precisely clamp and fix the gauze heddle frame. After the splicing process is completed, the positioning cylinder 42 is reset, the gauze heddle frame is released, and the finished product can be removed.
