Description

Technical Field

[0001] This utility model belongs to the technical field of loom heald frame crossbeams, specifically relating to a high-strength loom heald frame alloy crossbeam. Background Technology

[0002] The heald frame, as the core skeleton of the shedding mechanism, forms a rectangular whole through the upper and lower crossbeams and the left and right side rails. The heald rod and heald plates are suspended inside. Driven by the loom, it makes a high-frequency reciprocating linear motion, which precisely divides thousands of warp yarns into upper and lower sheds, providing a channel for the weft yarn to pass through smoothly and ensuring the correct formation of the fabric structure. Its rigidity, lightweight and fatigue resistance directly determine the weaving speed, fabric quality and equipment life. It is a key basic component for modern looms such as high-speed air-jet looms and rapier looms to achieve high-efficiency, low-breakage and high-value-added textile production.

[0003] In existing heddle frames, the crossbeams and side rails are fixed together with bolts during installation. After long-term use, external factors such as shearing forces between the crossbeams and side rails can cause the bolts to loosen, making the heddle frame prone to collapse and affecting its performance. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-strength loom heald frame alloy crossbeam includes: a crossbeam body, side stops connected to both ends of the crossbeam body, mounting blocks fixedly installed at both ends of the crossbeam body, connecting blocks fixedly installed at both ends of the side stops, the connecting blocks having a T-shaped cross-section, a connecting groove adapted to the connecting block being opened on the outer wall of the mounting block, the connecting block being disposed in the connecting groove, the mounting block and the connecting block being fixedly connected by multiple fixing bolts, the fixing bolts being disposed on the top of the mounting block, two symmetrically arranged clamping mechanisms being provided in the connecting groove, and a reinforcing component being provided on the crossbeam body;

[0007] The clamping mechanism includes an installation groove on the inner wall of the connecting groove, a movable block is slidably disposed on the inner wall of the installation groove, an anti-slip pad is fixedly disposed on the outer wall of the movable block, a through groove is opened on the inner wall of the installation groove, and an adjustment component is disposed inside the through groove.

[0008] Preferably, the adjusting component includes a fixed block fixedly disposed on the inner side wall of the through groove, a threaded rod passing through and rotatably disposed on the fixed block, the threaded rod and the movable block being threadedly connected, and the outer side wall of the movable block having a threaded groove adapted to the threaded rod.

[0009] Preferably, the mounting block is provided with a rotating rod at the top, the bottom of the rotating rod passes through the mounting block and extends into the through groove, and bevel gears are fixedly provided at the bottom of the rotating rod and the end of the threaded rod, and the two bevel gears are meshed together.

[0010] Preferably, worm gears are fixedly sleeved on the outer side walls of the top of both rotating rods, a fixing plate is fixedly installed on the top of the mounting block, the tops of the two rotating rods are rotatably mounted on the top of the fixing plate, a worm is rotatably mounted on the fixing plate, and the worm and the two worm gears are meshed together.

[0011] Preferably, a knob is fixedly provided at the end of the worm gear, and the outer wall of the knob is rotatably mounted on the outer wall of the fixed plate.

[0013] Preferably, the reinforcing component includes a cavity starting inside the beam body, wherein multiple reinforcing ribs are fixedly disposed at the bottom and top of the cavity.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By using the connecting block and connecting groove together, the shear load between the crossbeam body and the side guard is first transferred to the T-shaped keyway. Then, the anti-slip pads in the two sets of symmetrical clamping mechanisms are used to radially press the connecting block, so that the fixing bolt is only subjected to pure axial tension. This allows it to remain stable for a long time under high-speed reciprocating vibration environment, preventing the bolt from loosening and the heald frame from becoming loose, thus ensuring the performance of the heald frame. At the same time, the use of the internal cavity of the crossbeam and the reinforcing ribs significantly improves the bending stiffness and fatigue life without increasing the wall thickness.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figure 1 - Figure 5 As shown, a high-strength loom heald frame alloy crossbeam includes: a crossbeam body 1, side blocks 2 connected to both ends of the crossbeam body 1, mounting blocks 3 fixedly installed at both ends of the crossbeam body 1, connecting blocks 4 fixedly installed at both ends of the side blocks 2, the connecting blocks 4 having a T-shaped cross-section, a connecting groove adapted to the connecting blocks 4 being opened on the outer wall of the mounting blocks 3, the connecting blocks 4 being installed in the connecting groove, the mounting blocks 3 and the connecting blocks 4 being fixedly connected by multiple fixing bolts 5, the fixing bolts 5 being installed on the top of the mounting blocks 3, two symmetrically arranged clamping mechanisms being provided in the connecting groove, and a reinforcing component being provided on the crossbeam body 1;

[0025] The clamping mechanism includes an installation groove on the inner side wall of the connecting groove, a movable block 6 is slidably provided on the inner side wall of the installation groove, an anti-slip pad 7 is fixedly provided on the outer side wall of the movable block 6, and a through groove is provided on the inner side wall of the installation groove, with an adjustment component inside the through groove.

[0026] As can be seen from the above, the T-shaped connecting block 4 is first inserted vertically into the connecting groove, and then slides into the bottom axially. Its horizontal flange and the corresponding shoulder of the connecting groove form a pair of complementary T-shaped key surfaces. When a transverse shear force is generated between the beam body 1 and the side stop 2, the shear load is first transmitted through this pair of key surfaces, so that the fixing bolt 5 changes from shear-tension composite force to pure axial tension force, making the connection between the beam body 1 and the side stop 2 more stable. Thus, the heald frame can remain stable for a long time under high-speed reciprocating vibration environment, avoiding the loosening of the fixing bolt 5, which would make the heald frame easy to become loose, and ensuring the use effect of the heald frame.

[0027] By adjusting the components, the moving block 6 drives the anti-slip pad 7 to radially clamp the side of the connecting block 4. The anti-slip pad 7 (made of high friction coefficient materials such as rubber or polyurethane) effectively increases the friction of the contact surface, suppresses fretting wear, and eliminates the connection gap.

[0028] Specifically, regarding the aforementioned adjustment assembly, the adjustment assembly includes a fixed block 8 fixedly mounted on the inner side wall of the through groove, a threaded rod 9 passing through and rotatably mounted on the fixed block 8, a threaded connection between the threaded rod 9 and the movable block 6, and a threaded groove adapted to the threaded rod 9 being opened on the outer side wall of the movable block 6.

[0029] The top of the mounting block 3 is provided with a rotating rod 10. The bottom of the rotating rod 10 passes through the mounting block 3 and extends into the through groove. Both the bottom of the rotating rod 10 and the end of the threaded rod 9 are fixedly provided with bevel gears 11, and the two bevel gears 11 are meshed and connected.

[0030] Worm gears 12 are fixedly sleeved on the top outer walls of the two rotating rods 10. A fixing plate 13 is fixedly installed on the top of the mounting block 3. The tops of the two rotating rods 10 are rotatably mounted on the top of the fixing plate 13. A worm 14 is rotatably mounted on the fixing plate 13. The worm 14 and the two worm gears 12 are meshed and connected.

[0031] A knob 15 is fixedly installed at the end of the worm gear 14, and the outer side wall of the knob 15 is rotatably mounted on the outer side wall of the fixed plate 13.

[0032] The top and bottom of the movable block 6 are equipped with sliders, and the inner side wall of the mounting groove is provided with a sliding groove that matches the slider, and the slider is set in the sliding groove.

[0033] As can be seen from the above, during operation, rotating the knob 15 drives the worm gear 14, which in turn drives the two meshing worm wheels 12 to rotate. The worm wheels 12 then drive the rotating rod 10 to rotate. The bevel gear 11 at the bottom of the rotating rod 10 transmits the rotational motion to the bevel gear 11 connected to the threaded rod 9, ultimately driving the threaded rod 9 to rotate. The threaded rod 9 engages with the threaded groove on the moving block 6, converting the rotational motion into the horizontal linear motion of the moving block 6. The moving block 6 slides stably in the groove of the mounting slot through the top and bottom sliders, causing the anti-slip pad 7 on its outer wall to apply radial clamping force to the side of the connecting block 4. The self-locking characteristic between the worm wheel 12 and the worm gear 14 prevents the clamping force from returning under vibration.

[0034] Example 2:

[0035] Reference Figure 5 As shown, the reinforcing component includes a cavity starting inside the beam body 1, with multiple reinforcing ribs 16 fixedly disposed at the bottom and top of the cavity.

[0036] As can be seen from the above, by designing a cavity structure inside the beam body 1, and fixing multiple longitudinal reinforcing ribs 16 at the top and bottom of the cavity, these reinforcing ribs 16 form a highly efficient bending-resistant topology similar to an "I-beam", which is firmly combined with the inner wall of the beam. While reducing the weight of the beam body 1, the reinforcing ribs 16 evenly distribute the local load to the entire cross section, significantly improving the stiffness and load-bearing efficiency.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
