Description

Technical Field

[0001] The invention relates to an internal expansion type constant pressure multi-stranded wire clamp and a processing device thereof, belonging to the technical field of power wire clamps. Background Art

[0002] When laying power cables, it is often necessary to parallel the power cables. The existing method generally uses wire clamps for connection. Among them, the internal expansion parallel groove wire clamp is an electrical connector used on insulated wires of small and medium cross-sections. It is mainly composed of two upper and lower clamping plates and clamping blocks on both sides of the clamping plates. Due to its simple structure, it is widely used in power systems.

[0003] When clamping cables with current internal expansion parallel groove cable clamps, the clamping blocks on both sides of the clamp are usually flipped by turning a bolt knob to clamp the cable. However, during the clamping process, the flipping angles of the clamping blocks on both sides are not synchronized, resulting in different clamping pressures on the cable. Cables that are clamped for a long time are prone to loosening. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an internal expansion constant pressure multi-stranded wire clamp and a processing device thereof, which solves the problem in the prior art that the clamping blocks on both sides of the clamping plate rotate asynchronously resulting in different clamping pressures.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solution: an internal expansion type constant pressure multi-stranded wire clamp, comprising:

[0006] A lower splint, wherein both sides of the lower splint are bent inward to form a semicircular notch;

[0007] An upper clamping plate is provided above the lower clamping plate, with both sides of the upper clamping plate being recessed inward to form arc-shaped grooves, and the upper clamping plate and the lower clamping plate are connected by bolts;

[0008] A clamping block is arranged in the arc-shaped groove, a crescent-shaped clamping plate is provided on one side of the clamping block, the length of the clamping block is greater than the length of the lower clamping plate and the upper clamping plate, and a semicircular meshing tooth is provided on the end of the clamping block;

[0009] When the clamping blocks are installed, the semicircular meshing teeth on the two clamping blocks mesh with each other, and the two clamping blocks rotate synchronously.

[0010] By adopting the above technical solution, the rotation angles of the two clamping blocks when clamping the cable remain consistent, and the clamping force on the cables on both sides remains consistent, making the clamping of the cable by the wire clamp more stable. During the cable clamping process, the upper clamping plate is controlled to be close to the lower clamping plate, so that the clamping block connected to the arc-shaped groove rotates. After the two clamping blocks are engaged through the semicircular meshing teeth at the ends, they can achieve synchronous rotation, thereby clamping the cables on both sides at the same time, and the clamping angles of the two clamping blocks are symmetrical to each other during clamping. On the other hand, the clamping blocks can be confined in the arc-shaped groove by the semicircular meshing teeth, preventing the clamping blocks from falling off from the arc-shaped groove during the clamping process. Due to the setting of the mutually meshing semicircular meshing teeth, the clamping blocks will not get stuck during the process of clamping the cable. The two clamping blocks rotate synchronously and abut against the cable synchronously. When disassembled and repaired, the crescent clamps of the two clamping blocks are synchronously separated from the cable.

[0011] The present application also relates to a processing device for an internal expansion type constant pressure multi-stranded wire clamp, which is used to process the upper clamp and the lower clamp in the above-mentioned clamp, and the processing device includes:

[0012] A processing platform, wherein a drilling assembly is installed on the processing platform;

[0013] A transmission line is provided on the processing platform, the transmission line includes a set of symmetrically arranged transmission rails, the pre-processed upper clamping plate or lower clamping plate is slidably engaged with the two transmission rails through the arc-shaped grooves or semicircular notches on both sides thereof, and the transmission rails include a support plate, and the upper end of the support plate is provided with a circular guide support rod for sliding engagement with the arc-shaped grooves or the semicircular notches;

[0014] In which, a drilling section is provided on the transmission rail, the aperture of the drilling section is smaller than the aperture of the circular guide support rod, the connection between the drilling section and the circular guide support rod is a smooth transition surface, and the length of the drilling section is smaller than the length of the upper splint and the lower splint.

[0015] By adopting the above technical solution, it is possible to quickly drill holes in the upper and lower clamps of the wire clamp, improving the processing efficiency of the wire clamp. By providing a transfer rail that is compatible with the arc groove and the semicircular notch, the upper and lower clamps can be automatically transferred and drilled by the transfer rail during drilling, reducing the labor cost of wire clamp production and processing.

[0016] The present invention is further configured as follows: one end of the circular guide support rod is smoothly connected to a feeding rail, and the end of the feeding rail is bent toward both sides or the middle to form a feeding port.

[0017] By adopting the above technical solution, when drilling the upper clamping plate, the feed openings formed by the bends at both ends can guide the upper clamping plate, so that the arc-shaped groove on the upper clamping plate can be more accurately engaged with the transmission rail, thereby improving the loading speed of the upper clamping plate. Similarly, by bending the feed opening in the middle, the lower clamping plate can be guided, so that the semicircular notch on the lower clamping plate can be more accurately engaged with the transmission rail, thereby improving the loading speed of the lower clamping plate.

[0018] The present invention is further configured as follows: transmission rollers are provided between the support plates, and push blocks are provided on the transmission rollers at equal intervals.

[0019] By adopting the above technical solution, the workpiece on the transmission rail is pushed to move by the push block, thereby realizing automatic transmission of the workpiece.

[0020] The present invention is further configured as follows: a guide transverse plate is provided between the transmission rollers, and two side surfaces of the guide transverse plate are respectively connected to the support plate.

[0021] By adopting the above technical solution, the guide transverse plate can support the transmission roller, so that the workpiece being processed can be stably moved by the transmission roller.

[0022] The present invention is further configured as follows: a discharge plate is provided at one end of the processing platform, the discharge plate is inclined downward, and a discharge conveyor belt is provided below the processing platform.

[0023] By adopting the above technical solution, the workpiece after processing falls on the discharge plate and slides along the discharge plate onto the discharge conveyor belt, which can reduce the hard collision between the workpiece and the discharge conveyor belt after it falls, so that the workpiece can fall accurately onto the discharge conveyor belt.

[0024] The present invention is further configured as follows: the number of the transmission rollers is two, a gap is set between the two transmission rollers, a raised line with a width equal to the gap between the transmission rollers is set in the middle of the guide cross plate, and the thickness of the raised line is less than the thickness of the transmission rollers.

[0025] By adopting this technical solution, the raised line can separate the two conveyor belts and serve as a guide for the conveyor belts. The thickness of the raised line is smaller than that of the conveyor belts, providing vertical positioning while avoiding uneven conveyor surfaces or increased friction caused by excessively high raised lines, thus achieving a balance between stability and smoothness.

[0026] The present invention is further configured as follows: clamping strips are provided on both side surfaces of the guide transverse plate, a clamping groove is provided on the inner side of the support plate, and the guide transverse plate is slidably clamped between the support plates through the clamping strips and the clamping grooves.

[0027] This technical solution facilitates installation, allowing the guide plate to be quickly installed between the two support plates, reducing assembly time. Worn or damaged guide plates can be removed and replaced individually, eliminating the need for complete equipment disassembly and reducing downtime and maintenance costs.

[0028] The present invention is further configured as follows: the number of the guide transverse plates is two, the two guide transverse plates are symmetrically arranged between the support plates, and lifting plates are arranged at the ends of the guide transverse plates close to each other, and arc guide planes are arranged at both ends of the lifting plates.

[0029] By adopting this technical solution, the arcuate transition surfaces at each end of the lifting plate guide the conveyed object smoothly through the seam area between the two guide plates, avoiding scraping or jamming caused by right-angled edges. The lifting plate is set at the processing drilling point. After the lifting plate is used to lift the workpiece, it can be more closely aligned with the guide plates on both sides, leaving less room for it to shake during drilling, thereby improving drilling stability.

[0030] The beneficial effects of the present invention are:

[0031] By installing semicircular meshing teeth at both ends of the clamping block, the two semicircular meshing teeth mesh with each other, allowing the two clamping blocks to flip synchronously when clamping the cable. This can prevent the phenomenon of insufficient flip angle and insufficient clamping of a single clamp, ensuring that the two clamping blocks can clamp the cable synchronously and maintain roughly the same clamping force. At the same time, the semicircular meshing teeth at both ends of the clamping block can stably confine the entire clamping block to the arc-shaped groove on the upper clamping plate, preventing the clamping block from slipping out of the arc-shaped groove, making the clamp more stable when clamping the cable.

[0032] The installation of a transfer rail within the machining device effectively improves workpiece machining efficiency, enabling the device to drill holes in the workpiece in a stable and sequential manner. This eliminates the need for tedious manual workpiece mounting and fixing, reducing machining costs. Workpiece loading and unloading can be performed simultaneously during machining, simplifying operation. The transfer rail not only transports the workpiece but also supports the workpiece support and clamping device, facilitating rapid clamping and drilling of irregularly shaped workpieces, significantly improving drilling efficiency.

[0043] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further explained below with reference to specific illustrations.

[0044] like Figures 1 to 2 As shown, an internal expansion type constant pressure multi-stranded wire clamp includes: a lower clamping plate 1, an upper clamping plate 2 and a clamping block 3.

[0045] The lower clamping plate 1 has two sides that are bent inward to form semicircular notches 101. The upper clamping plate 2 is arranged above the lower clamping plate 1. The upper clamping plate 2 has two sides that are recessed inward to form arc-shaped grooves 201. The upper clamping plate 2 and the lower clamping plate 1 are connected by bolts 10. The clamping block 3 is arranged in the arc-shaped groove 201. A crescent-shaped clamping plate 301 is provided on one side of the clamping block 3. The crescent-shaped clamping plate 301 and the semicircular notch 101 together enclose a clamping channel for clamping the cable 4.

[0046] The length of the clamping block 3 is greater than that of the lower clamping plate 1 and the upper clamping plate 2. The end of the clamping block 3 is provided with a semicircular meshing tooth 302. When the clamping block 3 is installed, the semicircular meshing teeth 302 on the two clamping blocks 3 respectively mesh with each other, and the two clamping blocks 3 rotate synchronously.

[0047] Specifically, a slotted through-hole is provided at the center of the upper plate 2, extending from top to bottom. This hole allows for fine-tuning of the bolt 10's position laterally within a certain range, facilitating alignment during assembly. Similarly, a threaded through-hole (or pre-welded nut) is provided at the center of the lower plate 1, allowing the bolt 10 to be screwed into the lower plate 1 for initial securement, preventing it from falling out. When the upper and lower plates 2 and 1 are joined, the bolt 10 first passes through the threaded through-hole in the lower plate 1 before exiting through the slotted through-hole in the center of the upper plate 2. A nut 11 is then twisted onto the end for securement.

[0048] Furthermore, before the upper clamping plate 2 and the lower clamping plate 1 are spliced ​​together by the bolts 10, the two clamping blocks 3 are first clamped into the arc-shaped grooves 201 on both sides of the upper clamping plate 2. This can achieve rapid pre-positioning of the clamping blocks 3, avoid displacement or falling off of the clamping blocks 3 during assembly, and improve assembly efficiency.

[0049] In this embodiment, the arc angle of the arc groove 201 is greater than 180 degrees. The two curved plates that form the arc groove 201 have a small amount of elasticity. The clamping block 3 is engaged in the arc groove 201 via a cylindrical body 304 on one side. The cylindrical body 304 is axially limited by semicircular meshing teeth 302 provided on both sides of the clamping block 3, which can prevent the clamping block 3 from sliding in the arc groove 201. This makes the crescent-shaped clamping plate 301 on the clamping block 3 and the arc groove 201 more stable when clamping the cable 4, and prevents them from offsetting each other. After the cable clamp has clamped the cable 4, a plastic wrapping sleeve is provided on the outside of the clamp to wrap the entire clamp and prevent the external environment from interfering with the clamp's clamping point.

[0050] like Figure 2 As shown, the inner bottom surface of the lower plate 1 is provided with an upwardly protruding raised surface 102, the two sides of which smoothly connect to the inner surface of the semicircular notch 101. When the upper plate 2 is installed, its bottom abuts against the raised surface 102. The provision of the raised surface 102 prevents the crescent-shaped plate 301 on the side of the clamping block 3 from directly contacting the bottom surface of the lower plate 1 during rotation, thus preventing interference and wear between the clamping block 3 and the lower plate 1 during rotation.

[0051] Secondly, the upwardly protruding plane increases the thickness between the plates at the threaded hole position, thereby improving the strength of the middle position of the lower clamping plate 1, thereby increasing the maximum extrusion strength at this point and making the fastening strength of the bolt 10 greater.

[0052] Further, such as Figure 4 As shown, an inwardly concave groove 303 is provided in the middle of one side of the cylindrical body 304 of the clamping block 3. The width of the inwardly concave groove 303 is greater than the diameter of the bolt 10 used to fix the upper clamping plate 2 and the lower clamping plate 1. The provision of the inwardly concave groove 303 prevents interference between the cylindrical body 304 of the clamping block 3 and the bolt 10, and the clamping block 3 can rotate smoothly in the arc-shaped groove 201.

[0053] The present application also relates to a processing device for an internal expansion type constant pressure multi-stranded wire clamp, which is used for processing the upper clamping plate 2 and the lower clamping plate 1 in the above-mentioned wire clamp.

[0054] Example 1:

[0055] This embodiment is used for processing the upper splint 2.

[0056] like Figure 5 As shown, the processing device includes a processing platform 5, a drilling component 6 and a transmission line 7.

[0057] The entire processing platform 5 is supported by steel beams, the drilling assembly 6 is installed on one side above the processing platform 5, and the transmission line 7 is installed on the other side above the processing platform 5. The workpiece to be processed is sequentially transmitted to the drilling point of the drilling assembly 6 through the transmission line 7, and the workpiece is processed and drilled.

[0058] Specifically, such as Figure 6 As shown, the transmission line 7 includes a set of symmetrically arranged transmission rails 701. The pre-machined upper clamping plate 2 or lower clamping plate 1 slides and engages with the two transmission rails 701 via the arcuate grooves 201 or semicircular notches 101 on either side thereof. The transmission rails 701 include support plates 7012, with circular guide support rods 7011 disposed at their upper ends for sliding engagement with the arcuate grooves 201 or semicircular notches 101. The transmission rails 701 are provided with drilled sections 7013, the diameter of which is smaller than that of the circular guide support rods 7011. The connection between the drilled sections 7013 and the circular guide support rods 7011 forms a smooth transition surface, and the length of the drilled sections 7013 is shorter than that of the upper clamping plate 2 and the lower clamping plate 1. A transmission roller 703 is disposed between the support plates 7012, with push blocks 7031 disposed at equal intervals on the transmission roller 703. One end of the circular guide support rod 7011 is smoothly connected to the feeding rail 702, and the end of the feeding rail 702 is bent to both sides or the middle to form a feeding port.

[0059] In this embodiment, the ends of the two loading rails 702 are bent in opposite directions, toward the sides, and the two loading rails 702 are bent away from each other. The curved transition sections of the loading rails 702 toward the sides allow the operator to quickly slide the upper clamping plate 2 between the two transfer rails 701 without having to accurately align the arc-shaped groove 201 on the upper clamping plate 2 with the circular guide support rods 7011 on the transfer rails 701.

[0060] like Figure 7 As shown, the operator feeds the upper clamping plate 2 to be processed into the conveyor line 7 through the left feed port. The upper clamping plate 2 is pushed to the right by the push block 7031 on the conveyor roller 703. When it moves to the drilling section 7013, the conveyor roller 703 is controlled to stop and the drilling assembly 6 is driven to drill the upper clamping plate 2 at that point. After the drilling is completed, the conveyor roller 703 is controlled to move to drill the next upper clamping plate 2. After the drilling is completed, the upper clamping plate 2 moves to the right until the arc-shaped groove 201 slides out of the circular guide support rod 7011 and falls onto the next conveyor line 7.

[0061] In this embodiment, since the hole diameter in the middle of the drilling section 7013 is smaller than the hole diameter of the circular guide support rod 7011, and the length of the drilling section 7013 is smaller than the upper splint 2, when drilling the upper splint 2, the drill bit stroke position used for drilling is located at the point where the hole diameter is smallest in the middle of the drilling section 7013, so that the drill bit will not damage the circular guide support rod 7011 during the drilling process, and the circular guide support rods 7011 at both ends of the drilling section 7013 can also stably clamp and fix the upper splint 2.

[0062] Furthermore, the entire processing platform 5 is supported and fixed by support columns, the bottom of which is fixed to the ground. A straight slot is provided on the processing platform 5 between the support plates 7012 for the push block 7031 on the transmission roller 703 to pass through, thereby preventing interference during the operation of the transmission roller 703.

[0063] Furthermore, a guide plate 704 is provided between the transmission rollers 703, and both sides of the guide plate 704 are connected to the support plate 7012. The guide plate 704 can support the transmission rollers 703, so that when the transmission rollers 703 drag the upper clamping plate 2 to move, the upper clamping plate 2 can move stably along the movement direction of the transmission rollers 703, thereby preventing the transmission rollers 703 from bending downward.

[0064] Further, such as Figure 6As shown, the guide transverse plate 704 is provided with clamping strips 7042 on both sides, and the support plate 7012 is provided with a clamping slot 705 on the inner side. The guide transverse plate 704 is slidably clamped between the support plate 7012 through the clamping strips 7042 and the clamping slots 705. There are two guide transverse plates 704, and the two guide transverse plates 704 are symmetrically arranged between the support plate 7012.

[0065] During the installation of the guide cross plate 704, first, the two support plates 7012 are fixed to the processing platform 5, and the spacing between the two support plates 7012 is adjusted. After the support plates 7012 are installed, the transmission roller 703 is placed between the two support plates 7012. The guide cross plate 704 is inserted from both ends of the support plates 7012, and the clamping strips 7042 on both sides of the guide cross plate 704 are locked into the clamping slots 705. When the guide cross plate 704 is inserted between the support plates 7012, the position of the transmission roller 703 is moved so that the guide cross plate 704 inserted between the support plates 7012 is sandwiched between the transmission roller 703 and the inner circle. When the second guide cross plate 704 is inserted, the transmission roller 703 and the first guide cross plate 704 are further moved so that the second guide cross plate 704 is also sandwiched between the inner circle by the transmission roller 703. After the guide cross plate 704 is installed, the rotating shafts at both ends of the transmission roller 703 are installed on both ends of the processing platform 5, and the driving motor is installed for driving.

[0066] Further, such as Figures 6 to 8 As shown, a lifting plate 706 is provided at the ends of the two guide horizontal plates 704 close to each other, and arc guide planes are provided at both ends of the lifting plate 706, which can support the workpiece to be processed, so that after the workpiece moves upward along the arc guide plane for a certain distance, it fits with the circular guide support rod 7011, and generates relatively small vibration when drilling.

[0067] The lifting plate 706 is clamped between the two guide transverse plates 704 and can be fixed by riveting, splicing or bonding.

[0068] Furthermore, a discharge plate 8 is provided at one end of the processing platform 5 , and the discharge plate 8 is inclined downward. A discharge conveyor belt 9 is provided below the processing platform 5 .

[0069] After the workpiece is processed and drilled, it continues to move forward and detaches from the other end of the conveyor line 7. After falling onto the discharge plate 8, it is guided by the discharge plate 8 and falls onto the unloading conveyor belt 9 under the processing platform 5. It is then transported to the designated collection point through the unloading conveyor belt 9 for centralized collection.

[0070] like Figure 6As shown, there are two transmission rollers 703, each transmission roller 703 is provided with a push block 7031, a gap is provided between the two transmission rollers 703, and a raised line 7041 with a width equal to the gap between the transmission rollers 703 is provided in the middle of the guide cross plate 704, and the thickness of the raised line 7041 is less than the thickness of the transmission roller 703.

[0071] The arrangement of the two transmission rollers 703 can cooperate with the arc guide plane to avoid the upwardly protruding arc guide plane from interfering with the transmission roller 703. The processed workpiece can be smoothly lifted after being transferred to the arc guide plane.

[0072] Example 2:

[0073] This embodiment is used for processing the lower splint 1 .

[0074] When drilling the lower clamping plate 1 , the lower clamping plate 1 can be clamped, transported and drilled by replacing the drill bit on the drilling assembly 6 and adjusting the spacing between the support plates 7012 .

[0075] Specifically, such as Figure 5 As shown, three rows of plug holes for installing support plates 7012 are provided on the processing platform 5, and the number of plug holes in each row is at least two. A plug foot 707 is fixed to the bottom of the support plate 7012. By selecting different plug holes to install the support plate 7012, the spacing between the support plates 7012 can be adjusted to accommodate upper splints 2 and lower splints 1 of different sizes.

[0076] In this embodiment, the length of the push block 7031 used to push the lower clamping plate 1 is greater than the length of the push block 7031 used to push the upper clamping plate 2 in the previous embodiment.

[0077] like Figure 9 As shown, the ends of the loading rails 702 are bent in opposite directions, toward the inside, and the two loading rails 702 are bent closer to each other. The feed opening formed by the inward bending can guide the lower clamping plate 1, so that the semicircular notch 101 on the lower clamping plate 1 can be more accurately engaged with the transfer rails 701, thereby increasing the loading speed of the lower clamping plate 1.

[0078] During the processing of the lower splint 1, the staff first clamps the lower splint 1 onto the transmission line 7 from the end of the loading rail 702. During the movement of the transmission roller 703, it is pushed forward by the push block 7031, so that the semicircular groove 101 on the lower splint 1 is clamped with the circular guide support rod 7011, and moves axially along the circular guide support rod 7011 under the push of the transmission roller 703.

[0079] Working principle:

[0080] When clamping the cable 4, first insert the two clamping blocks 3 into the arc-shaped grooves 201 on both sides of the upper clamping plate 2, so that the clamping blocks 3 can rotate a certain angle in the arc-shaped grooves 201. Connect the upper clamping plate 2 and the lower clamping plate 1 with bolts 10 and nuts, so that the curved surfaces of the crescent-shaped clamping blocks 301 on the two clamping blocks 3 and the semicircular notches 101 on the lower clamping plate 1 form a ring channel with a larger inner diameter. Insert the cable to be clamped and connected into the ring channel, adjust the clamping position, and then press the clamping block 301 into the ring channel. Figure 3 and Figure 4 As shown, by turning the knob bolt 10 and the nut, the lower clamping plate 1 and the upper clamping plate 2 are brought closer to each other, and one side of the crescent-shaped clamping plate 301 first abuts against the cable. As the bolt 10 continues to rotate, the clamping block 3 will rotate with the axis as the center of the circle, so that the arc surface of the crescent-shaped clamping plate 301 gradually abuts against the cable, clamping the cable in the annular channel. During the rotation of the clamping block 3, since both ends of the clamping block 3 are provided with semicircular meshing teeth 302, and since the semicircular meshing teeth 302 are mutually engaged, the two clamping blocks 3 can rotate and clamp synchronously, and the final rotation angle can be consistent, so that the clamping force of the two clamping blocks 3 on the cable remains within the same range. And because the semicircular meshing teeth 302 at the end limit, no axial movement or slippage will occur during the rotation and clamping process of the clamping block 3, so that the cable can be clamped more stably.

[0081] When the processing device drills a hole in the upper splint 2, the worker sequentially inserts the upper splint 2 to be processed into the loading rail 702, pushes it along the loading rail 702 onto the circular guide support rod 7011, and is pushed by the push block 7031 on the transmission roller 703, which moves synchronously with the transmission roller 703. When it moves to the drilling section 7013, the transmission roller 703 stops moving. At this time, the circular arc guide plane on the lifting plate 706 lifts the upper splint 2 upward for a distance, so that the arc groove 201 on the upper splint 2 and the circular guide support rod 7011 fit more closely with each other, thereby fixing the upper splint 2. After the transmission roller 703 stops moving, the drilling assembly 6 starts working to drill a hole in the upper splint 2. After drilling is completed, the conveyor roller 703 continues to move, pushing the upper clamp 2 after drilling is completed to move forward, so that the upper clamp 2 slides from the circular guide support rod 7011 to the discharge plate 8, and falls into the discharge conveyor belt 9 under the guidance of the discharge plate 8, and is transported to the designated collection point through the discharge conveyor belt 9.

[0082] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art will appreciate that the present invention is not limited to the foregoing embodiments and that various modifications and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such modifications and improvements are intended to fall within the scope of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
