Description

Technical Field

[0001] This utility model relates to the field of automatic crimping technology, and in particular to a crimping assembly. Background Technology

[0002] In automated crimping production, machine cutting and changeover operations are often required to adapt to the production needs of different products and improve production efficiency. The crimping head, as a core component of automated crimping equipment, directly impacts production efficiency and crimping quality through its installation. Existing technologies present several problems with crimping head installation: firstly, the installation process is cumbersome, hindering rapid machine cutting and resulting in long downtime, significantly reducing production efficiency; secondly, ensuring consistent crimping head installation is difficult, leading to crimping position deviations and uneven pressure, resulting in low crimping yield, increased production costs, and negatively impacting the company's economic benefits. Furthermore, existing crimping head installation structures are inadequate in terms of adjustment and positioning, lacking convenient and precise positioning devices and quick-release structures, making it difficult to meet the high-efficiency and stable requirements of automated production. Therefore, there is an urgent need to design a crimping head installation structure that enables rapid machine cutting and ensures consistent installation to improve customer production efficiency and crimping yield. Utility Model Content

[0003] In order to solve all or part of the problems of the prior art, this utility model provides a pressing assembly, which realizes rapid adjustment and reliable locking of the pressing head spacing by setting a combination structure of parallel guide groove and slider on the adjusting base.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A crimping assembly includes an adjusting base and a plurality of pressing heads mounted thereon. The upper surface of the adjusting base has at least one parallel extending guide groove along its length. A slider that can move along its extension direction is correspondingly disposed in the guide groove. The pressing head is detachably connected to the slider by a locking member. When the locking member is tightened, the contact surface between the slider and the guide groove generates a frictional locking force, so that the pressing head and the slider are synchronously fixed at a set position in the guide groove.

[0006] It also includes a mounting base, a first mounting plate and a second mounting plate connected in sequence. The adjusting base and the pressure head thereon are detachably mounted on the lower surface of the second mounting plate through a quick positioning structure.

[0007] The quick positioning structure includes: a plurality of U-shaped positioning grooves evenly distributed along one edge of the second mounting plate, with their openings facing the adjustment base; and a T-shaped positioning block correspondingly disposed on the upper surface of the adjustment base, wherein the neck width of the T-shaped positioning block and the opening width of the U-shaped positioning groove form a clearance fit.

A threaded hole matching the adjusting base is provided at the corresponding position. A handle is provided at the upper end of the adjusting bolt.

[0009] The locking knob also includes a compression spring sleeved on the adjusting bolt. The compression spring is located between the upper surface of the second mounting plate and the handle. When the handle is pressed down and rotated, the compression spring generates an axial preload to make the second mounting plate fit tightly against the adjusting base.

[0010] The sidewall of the guide rail groove is provided with positioning scale.

[0011] The first mounting plate is provided with multiple threaded countersunk holes, and the second mounting plate is provided with bolt through holes at corresponding positions.

[0022] The technical solutions in specific embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] In this embodiment of the utility model, in conjunction with reference to the reference Figures 1 to 5 As shown, a crimping assembly is provided, including a mounting base 3, a first mounting plate 4, a second mounting plate 5, an adjusting base 1, and a plurality of crimping heads 2 connected in sequence.

[0025] The mounting base 3 and the first mounting plate 4 are connected by a rotation adjustment structure 6. This structure includes a connecting part 601 for positioning and fixing and a rotating part 602 for adjusting the angle. It can realize the angle adjustment and locking of the first mounting plate 4 relative to the mounting base 3, and ensure that the first mounting plate 4, the second mounting plate 5, the adjusting base 1, and the pressure head 2 rotate synchronously around an axis parallel to the bearing surface of the platform. The rotating part 602 includes a cylindrical rotating shaft that is vertically fixed to the upper center of the mounting base 3. The axis of the rotating shaft is parallel to the bearing surface of the platform unit. A bearing assembly that rotates with the rotating shaft is embedded at the corresponding position of the first mounting plate 4. Through the interference fit between the inner ring of the bearing and the rotating shaft and the clearance fit between the outer ring of the bearing and the mounting plate, a hinged connection that can rotate 360° is formed. The connecting part 601 is disposed on both sides of the mounting base 3, specifically including: at least two elongated through holes opened on the side of the mounting base 3, threaded countersunk holes disposed at corresponding positions on the first mounting plate 4, and adjusting bolts passing through the elongated through holes and engaging with the threaded countersunk holes; when the adjusting bolts are loosened, the first mounting plate 4 can rotate slightly around the rotation axis, and the sliding range of the adjusting bolts in the elongated through holes limits the angle adjustment range; when the bolts are tightened, the angular position of the first mounting plate 4 can be locked by the friction between the bolt head and the surface of the mounting base 3. To achieve high-precision angle fine adjustment, horizontal adjustment structures 7 are also symmetrically arranged on both sides of the mounting base 3, which are used in conjunction with the rotation adjustment structure 6. This structure includes a support fixed to the side of the mounting base 3, an adjusting nut embedded in the support, and a fine-tuning screw forming a threaded pair with the adjusting nut. The top surface of the fine-tuning screw abuts against the bottom surface of the first mounting plate 4 through a pad. The outer surface of the screw is provided with a thousand-level thread scale. By rotating the fine-tuning screw clockwise or counterclockwise, the first mounting plate 4 can be precisely rotated around the rotation axis by the small feed amount of the thread transmission. With the bolt locking of the connecting part 601, the angle adjustment of the crimping assembly can be realized within a certain range.

[0026] When the pressing surface of the pressure head 2 deviates from the parallelism of the bearing surface of the platform, angle compensation can be achieved through the rotation adjustment structure 6 and the horizontal adjustment structure 7 between the mounting base 3 and the first mounting plate 4. The specific adjustment process is as follows: First, loosen the adjusting bolt of the connecting part 601 to release the locking state between the first mounting plate 4 and the mounting base 3. At this time, the first mounting plate 4 can rotate slightly around the rotation axis (which is parallel to the bearing surface of the platform) that is vertically fixed to the mounting base 3. Simultaneously rotate the fine-tuning screw in the horizontal adjustment structure 7 on both sides, and use the thousand-level thread scale on the outer surface of the screw to make precise angle fine-tuning. When the fine-tuning screw is rotated clockwise or counterclockwise, the pad on the bottom surface of the first mounting plate 4 is pushed through the thread pair transmission, thereby driving the entire pressing assembly to rotate around the rotation axis until the parallelism between the pressing surface and the bearing surface of the platform meets the process requirements. Finally, tighten the adjusting bolt, and lock the angle position of the first mounting plate 4 through the friction between the elongated through hole and the bolt head, so that the pressing surface of the pressing assembly always remains parallel to the bearing surface of the platform during the pressing process. This adjustment mechanism achieves high-precision calibration of the parallelism of the pressing surface through the linkage design of the mechanical structure, effectively avoiding uneven pressing pressure or positional deviation caused by angular deviation.

[0027] The top surface of the mounting base 3 is provided with a wire fixing part 301, which includes an elastic pressure plate assembly. Specifically, one end of the elastic pressure plate is rotatably connected to a hinge seat on the top surface of the mounting base 3 via a cylindrical pin, allowing the elastic pressure plate to rotate within a 0-180° range around the pin axis. The other end of the elastic pressure plate is provided with a hook portion, which, together with a corresponding annular buckle fixed on the mounting base 3, forms a detachable locking structure. The main body of the elastic pressure plate is made of 65Mn spring steel after quenching and tempering. A high-elasticity silicone buffer layer of a certain thickness is adhered and fixed to its inner surface facing the wire. The surface of this buffer layer has a grid-like anti-slip texture, which can effectively prevent displacement or surface scratches of the wire due to vibration during the crimping process. When it is necessary to fix the wire, press down on the free end of the elastic pressure plate to make the hook part engage with the locking groove of the annular buckle for fixation. The clamping force generated by the deformation of the elastic pressure plate itself presses the wire firmly onto the positioning plane of the mounting base 3. To release the fixation, pull up on the free end of the elastic pressure plate to disengage the hook part from the locking groove to unlock. This wire fixing part 301 achieves reliable positioning of the input and output wires during crimping operations through a dual fixing mechanism of elastic clamping and self-locking buckle. At the same time, the silicone buffer layer takes into account both wire protection and anti-slip requirements.

[0028] The upper surface of the adjusting base 1 has at least one parallel extending guide groove 101 along its length. The guide groove 101 adopts a dovetail groove structure with a trapezoidal or rectangular cross-section. A slider that can slide along its extension direction is correspondingly arranged in each guide groove 101. The pressure head 2 is detachably connected to the slider through a locking member. Specifically, the locking member is a fastening bolt that penetrates the pressure head 2, and the end of the bolt forms a threaded pair with the threaded hole at the top of the slider. When the fastening bolt is tightened, an axial preload is generated between the fixing part and the slider, so that the top surface of the slider is tightly fitted with the top of the guide groove 101. At the same time, the side of the slider forms a line contact or surface contact with the side wall of the guide groove 101. The frictional locking force generated between the contact surfaces fixes the slider in the set position of the guide groove 101, thereby locking the position of the pressure head 2 on the adjusting base 1. This structural design allows the spacing of the pressure head 2 to be adjusted along the guide rail groove 101 according to the crimping point layout of the product to be tested, and to be quickly fixed by a single bolt locking method, ensuring the stability of the position of the pressure head 2 during the crimping operation.

[0029] The adjusting base 1 and the pressure head 2 thereon are detachably mounted on the lower surface of the second mounting plate 5 via a quick-positioning structure. This structure includes multiple U-shaped positioning grooves 501 evenly distributed along one edge of the second mounting plate 5, with their openings facing the adjusting base 1. It also includes T-shaped positioning blocks 102 correspondingly disposed on the upper surface of the adjusting base 1, the neck width of the T-shaped positioning blocks 102 forming a clearance fit with the opening width of the U-shaped positioning grooves 501. Each U-shaped positioning groove 501 has a locking knob 502 on its side. The locking knob 502 includes an adjusting bolt that passes through the second mounting plate 5, and a threaded hole matching it is opened at the corresponding position on the adjusting base 1. The upper end of the adjusting bolt has a handle. The locking knob 502 also includes a compression spring sleeved on the adjusting bolt. The compression spring is located between the upper surface of the second mounting plate 5 and the handle. When the handle is pressed down and rotated, the compression spring generates an axial preload force to make the second mounting plate 5 and the adjusting base 1 fit tightly together. With the above structure, the adjusting base 1 can be quickly positioned and fixed on the second mounting plate 5. The cooperation between the T-shaped positioning block 102 and the U-shaped positioning groove 501 ensures the installation accuracy, while the compression spring design of the locking knob 502 provides a stable preload, ensuring the reliability of the connection. The side wall of the guide rail groove 101 of the adjusting base 1 is also provided with positioning scales to indicate the position of the pressure head 2 in the guide rail groove 101.

[0030] The first mounting plate 4 has multiple threaded countersunk holes, and the second mounting plate 5 has corresponding bolt through holes. The two are fixedly connected to the threaded countersunk holes by fastening bolts that pass through the bolt through holes.

[0031] This utility model significantly improves the performance and production efficiency of automatic crimping equipment through a series of innovative designs. Specifically, its innovations and advantages include: First, the combination of the rotary adjustment structure 6 and the horizontal adjustment structure 7 achieves high-precision calibration of the parallelism of the crimping surface, effectively compensating for angular deviations and ensuring that the crimping surface and the bearing surface of the platform remain parallel at all times. This avoids uneven crimping pressure or positional offset caused by angular issues, greatly improving crimping quality and stability. Second, the wire fixing part 301, composed of the elastic pressure plate assembly, utilizes a dual fixing mechanism of elastic clamping and self-locking buckles, combined with a silicone buffer layer, to ensure the reliability of wire positioning and prevent wire damage, further enhancing the stability of the crimping operation. Third, the structural design of the guide rail groove 101 and the slider allows the pressure head 2 to quickly adjust the spacing and lock according to requirements, meeting the crimping requirements of different products. Fourth, the quick positioning structure, through the precise fit between the T-shaped positioning block 102 and the U-shaped positioning groove 501, and the locking knob 502 with a compression spring, achieves rapid, accurate installation and reliable fixation of the adjusting base 1, improving cutting and changeover efficiency. Furthermore, the positioning scale facilitates precise adjustment of the pressure head 2 position, and the detachable connection design between components enhances the maintainability and flexibility of the equipment. In summary, this utility model, through multifaceted innovative design, comprehensively solves the problems of cumbersome installation and poor consistency of the pressure head 2 in existing technologies, effectively improving production efficiency and crimping yield, and possesses significant practical value and market prospects.

[0032] It should be noted that, for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the scope of protection of the claims of this utility model.
