Description
Technical Field
[0001] The utility model belongs to the technical field of the production and manufacturing of electric power fittings. Specifically, it particularly relates to a linkage pressing device for drilling pin shafts of a flip-type electric power fitting clamp, and an electric power fitting clamp, which has a unique and ingenious concept, can ensure that each drilling point of the clamp is the "optimal point for the flip cover and the clamp body to embrace each other", has high-quality clamp products manufactured, effectively avoids the cumulative error formed by separate processing, has a fast hole alignment speed, good product consistency, effectively reduces the production process of the clamp, greatly improves the production efficiency, is easy to implement the method, and has a low implementation cost. Background Technique
[0002] The flip-type electric power fitting clamp is an indispensable component in the transmission line. It realizes quick installation and disassembly through the flip structure. The most common flip-type electric power fitting clamp is the spacer clamp applied to the spacer. The flip cover and the clamp body are the core components of the clamp. Pin shaft holes are opened on both the flip cover and the clamp body, and a pin shaft is inserted into the pin shaft hole, so as to realize the flip-type movable connection between the flip cover and the clamp body.
[0003] The pin shaft holes on the traditional flip cover and the clamp body are drilled separately. After drilling, the flip cover and the clamp body are assembled and a pin is inserted. Then, the hole of the pin shaft hole is blocked by a welding process. However, the traditional production method has the following defects:
[0004] First, the product quality is unstable. After the finished product is made, some flip covers of the clamp cannot be fully opened, and some clamps cannot clamp the wire tightly. This is because the separate processing method of the flip cover and the clamp body is prone to error accumulation. Even a tiny deviation will be amplified during assembly, resulting in some flip covers of the clamp not being able to be fully opened and some flip clamps being too loose to lock tightly. As a result, the quality of the clamp products is unstable, the consistency is poor, and the reliability is poor.
[0005] Second, it is difficult to position the holes. The flip cover and the clamp body are drilled separately, and it is difficult to ensure that the positioning accuracies of the two processes are the same, resulting in difficulties in hole alignment during subsequent assembly, long hole alignment time, and an increased probability of product instability.
[0006] Third, the process is cumbersome and the operation is complex. The flip cover and the clamp body need to be loaded, drilled, and unloaded separately. The operation steps are cumbersome, the labor intensity of workers is high, the production efficiency is low, and the utilization rate of the drilling equipment is low.
[0007] Fourth, the material utilization rate is low. From the first and second points, it can be seen that the traditional processing method is prone to a high scrap rate. Once any of the two phenomena that the flip cover of the clamp cannot be fully opened or the clamp cannot clamp the wire tightly occurs, the entire semi-finished product has to be scrapped. Each piece of scrap means a loss of raw materials, labor, machine running time, and subsequent processing costs. Summary of the Invention

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components.

[0043] Embodiment 1
[0044] The clamp of the electrical fitting has high requirements for the clamping of the clamp flip cover 11 and the clamp body 12. The clamping between the clamp flip cover 11 and the clamp body 12 cannot be too tight, otherwise the clamp flip cover 11 cannot be fully opened, resulting in the wire being unable to enter the wire accommodation space formed by the clamp flip cover 11 and the clamp body 12 during actual installation; the clamping between the clamp flip cover 11 and the clamp body 12 cannot be too loose either, otherwise the clamp flip cover 11 and the clamp body 12 cannot clamp the wire after being locked. Therefore, after the clamp flip cover 11 and the clamp body 12 are assembled, the state of "the clamp flip cover can be fully opened and the clamp can clamp the wire when locked" should be achieved, and this state is the "ideal working state" that each qualified clamp should reach.
[0045] As Figure 1 shown, a linkage type pressing device for drilling pin shaft holes of a flip type electrical fitting clamp in this embodiment includes a bottom plate 51. A middle clamping rod 21 with a middle clamping piece 22 installed thereon is fixedly arranged on the bottom plate 51. The clamp flip cover 11 and the clamp body 12 are clamped with the middle clamping rod 21 as the position reference, and a separation gap is left between the locking inner end faces of the clamp flip cover 11 and the clamp body 12 through the middle clamping piece 22. A linkage mechanism 3 for pressing the clamp flip cover 11 and the clamp body 12 simultaneously from both sides of the clamp 1 is also installed on the bottom plate 51. The bottom plate 51 is fixed on the workbench 42 of the drilling equipment 4, and the drilling equipment 4 is preferably a drilling machine.
[0046] The specific operation steps of this embodiment are as follows:
[0047] Step 1: Set the middle clamping rod 21 and use the middle clamping rod 21 as the filler between the wire grooves of the clamp flip cover 11 and the clamp body 12; use the middle clamping rod 21 to simulate the rubber part of the clamp and the wire to be clamped by the clamp.
[0048] Step 2: Clamp the wire clamp flip cover 11 and the wire clamp body 12 with the middle clamping rod 21 as the reference position; when clamping, there is a separation gap between the locking inner end face of the wire clamp flip cover 11 and the locking inner end face of the wire clamp body 12 through the middle clamping piece 22; the middle clamping rod is the first step to find the "optimal clamping point of the wire clamp flip cover and the wire clamp body", and the middle clamping piece is the second step to find the "optimal clamping point of the wire clamp flip cover and the wire clamp body". The design of the middle clamping piece is one of the cores of the present utility model. For the method of one-time forming by clamping, there will be no phenomenon that "some wire clamp flip covers cannot be fully opened and some wire clamps cannot clamp the wire tightly", but there may be a single phenomenon that "the wire clamp flip covers cannot be fully opened" or "the wire clamps cannot clamp the wire tightly" both occur. The phenomenon that "the wire clamp flip cover cannot be fully opened" is because the wire clamp flip cover 11 and the wire clamp body 12 are clamped too tightly when initially clamped. The phenomenon that "the wire clamp cannot clamp the wire tightly" is because the wire clamp flip cover 11 and the wire clamp body 12 are clamped too loosely when initially clamped. Therefore, there is a separation gap between the locking inner end face of the wire clamp flip cover 11 and the locking inner end face of the wire clamp body 12 through the middle clamping piece 22, and this separation gap will ensure that each product can reach the "ideal working state". Of course, for wire clamps of different specifications, middle clamping pieces 22 with different thicknesses will be selected.
[0049] Step 3: Use the linkage mechanism 3 to simultaneously press the wire clamp flip cover 11 and the wire clamp body 12 from both sides of the wire clamp 1, so as to lock the position of the wire clamp 1; the linkage mechanism 3 is based on the middle clamping rod 21 and the middle clamping piece 22, and simultaneously presses the wire clamp flip cover 11 and the wire clamp body 12 from both sides of the wire clamp, so that the wire clamp flip cover 11 and the wire clamp body 12 are kept in the state of "optimal clamping point of the wire clamp flip cover and the wire clamp body".
[0050] Step 4: Align the drilling point of the wire clamp 1 described in Step 3 with the drilling bit 41 of the drilling device 4, start and feed the drilling bit 41, so that the pin hole of the flip-type electric power fitting wire clamp can be formed in one time.
[0051] This embodiment is uniquely conceived, easy to implement, and has a low implementation cost. First, the clamp flap and the clamp body are embraced, and the intermediate clamping rod is used as the first step to find the "optimal point for the embrace of the clamp flap and the clamp body". Subsequently, the intermediate clamping piece is used as the second step to find the "optimal point for the embrace of the clamp flap and the clamp body". Finally, the linkage mechanism tightly holds the clamp flap and the clamp body synchronously from both sides of the clamp, thereby locking the "optimal point for the embrace of the clamp flap and the clamp body". This embodiment locks the "optimal point for the embrace of the clamp flap and the clamp body" from the initial processing. The drilling accuracy of the pin holes is very high, and each product manufactured can reach the "ideal working state", that is, the clamp flap can be fully opened, and at the same time, the clamp can also be tightened. Moreover, in this process, this embodiment realizes the one-step drilling of the clamp flap and the clamp body, effectively avoiding the influence of error accumulation caused by separate processing on the clamp accuracy, and further ensuring the accuracy of the drilling of the clamp pin holes. The products manufactured by this embodiment have good consistency, stable performance, and high product reliability.
[0052] The one-step drilling of the clamp flap and the clamp body in this embodiment also effectively simplifies the clamp drilling process, reduces the process complexity, significantly reduces the labor intensity, and greatly improves the production efficiency.
[0053] This embodiment fundamentally solves the problem of high scrap rate caused by separate processing of the traditional clamp pin holes, greatly saves the material cost, and also further reduces the production cost from the perspective of shortening the operation time of labor and machines.
[0054] The method of this embodiment is very practical, creates considerable economic benefits for enterprises, and has important guiding significance for the manufacture of electric power fitting clamps.
[0055] Embodiment 2
[0056] On the basis of Embodiment 1, this embodiment continues to describe in detail the technical features involved and the functions and roles played by these technical features in the present invention, so as to help those skilled in the art fully understand the technical solution of the present invention and reproduce it.
[0057] Such as Figures 1 to 7As shown in the figure, the linkage mechanism 3 of this embodiment includes an inner pressing member 31 and an outer pressing member 32 that achieve synchronous movement through a push rod 331 provided with a pushing block 332; the push rod 331 makes a reciprocating movement in the axial direction under the drive of the power unit 33; the inner pressing member 31 includes an inner push plate 311 fixedly connected to the push rod 331, and an inner pressing block assembly 313 for pressing one side of the wire clamp 1 is fixedly provided on the inner push plate 311; the outer pressing member 32 includes an outer rotating push plate 321, and the middle position of the outer rotating push plate 321 is the rotation point; an interference-free hollow groove 322 is provided at one end of the outer rotating push plate 321, and the free end of the push rod 331 passes through the interference-free hollow groove 322, and the pushing block 332 cannot pass through the interference-free hollow groove 322; an outer pressing block assembly 324 for pressing the other side of the wire clamp 1 is fixedly installed at the other end of the outer rotating push plate 321; the outer rotating push plate 321 also has the ability to reset under the action of the reset mechanism 34. Generally, a cylinder is selected as the power unit 33, and the piston rod of the cylinder is fixedly connected to the push rod 331.
[0058] The operation steps of this embodiment are as follows:
[0059] Step 1: Set the intermediate clamping rod 21, and use the intermediate clamping rod 21 as the filler between the wire groove of the wire clamp flap 11 and the wire groove of the wire clamp body 12; use the intermediate clamping rod 21 to simulate the rubber part of the wire clamp and the wire to be clamped by the wire clamp.
[0060] Step 2: Clamp the wire clamp flap 11 and the wire clamp body 12 with the intermediate clamping rod 21 as the reference position; when clamping, there is a separation gap between the locking inner end surface of the wire clamp flap 11 and the locking inner end surface of the wire clamp body 12 through the intermediate clamping piece 22. For convenient positioning, a drilling positioning indicator is provided on the intermediate clamping rod 21; the drilling positioning indicator is a bushing plate 23 provided with a bushing 231; the bushing plate 23 is fixedly connected to the intermediate clamping rod 21 in a unique assembly relationship, and the center of the bushing 231 is coaxial with the pin hole of the wire clamp 1. When the bushing 231 is aligned with the drilling bit 41, the center of the bushing 231 and the pin hole of the wire clamp 1 are both on the central axis of the drilling bit 41. That is to say, in the initial stage of device design, after clamping with the intermediate clamping rod 21 and the intermediate clamping piece 22 as the reference position, determine the drilling point of the pin hole, and keep the center of the bushing 231 coaxial with the drilling point, so as to determine the position of the bushing 231 on the intermediate clamping rod 21. To avoid the offset of the bushing 231 caused by factors such as vibration, the bushing 231 and the intermediate clamping rod 21 can adopt a matching method of concave and convex grooves to determine a unique assembly relationship.
[0061] Step 3: Use the linkage mechanism 3 to simultaneously press the wire clamp flap 11 and the wire clamp body 12 from both sides of the wire clamp 1, so as to lock the position of the wire clamp 1.
[0062] Step 4: Align the drilling point of the wire clamp 1 described in step 3 with the punching drill 41 of the drilling device 4, start and feed the punching drill 41, so that the pin shaft hole of the flip-top power hardware wire clamp can be punched in one go. The drilling device 4 is a drilling machine, and the punching drill 41 is a drilling machine drill bit.
[0063] When the power unit 33 is in a retracted state, the device to which the linkage one-time molding method of the utility model is applied is in a "non-compression state" (referred to as "state one"); when the power unit 33 is in an extended state, the device to which the linkage one-time molding method of the utility model is applied is in a "compression state" (referred to as "state two"). Figure 1 , Figure 2 , Figure 3 , Figure 6 What is shown is the "non-compression state". Figure 7 What is displayed is the "compression state".
[0064] Before the formal batch processing, the position of the sleeve 231 and the punching drill 41 is pre-aligned so that the drilling point of the wire clamp 1 clasped on the middle clamp rod 21 falls on the central axis of the punching drill 41. Using the sleeve 231 as a guide makes it easier to align the punching drill 41 with the drilling point. Although step four is the drilling point alignment process, the actual alignment process only needs to be performed once; that is, after aligning the sleeve 231 with the punching drill 41 of the drilling device 4 before the first batch processing, the position of the device to which the linkage one-time molding method of the present invention is applied is fixed, and the subsequent processing does not need to operate the drilling point alignment process.
[0065] The specific action process of this embodiment is as follows:
[0066] The wire clamp flap 11 and the wire clamp body 12 are embraced with the middle clamp rod 21 as the head reference position. The power unit 33 is started, and the power unit 33 pushes the push rod 331 to extend. The inner push plate 311 fixed on the push rod 331 moves in conjunction with the push rod 331, thereby further driving the inner pressure block assembly 313 to press one side of the wire clamp 1. At the same time, the pushing block 332 cannot pass through the interference-free hollow groove 322. The extension of the push rod 331 causes the pushing block 332 to push the outer rotating push plate to rotate with the middle position as the rotation point. The design of the interference-free hollow groove 322 is to provide movement space for the rotation of the outer rotating push plate 321. The rotation of the outer rotating push plate 321 causes the outer pressure block assembly 324 to also synchronously press the other side of the wire clamp 1. After tightening, the locking inner end faces of the wire clamp cover 11 and the wire clamp body 12 are respectively fitted with the two sides of the middle clamp 22. Under the action of the middle clamp 22, a separation gap is left between the locking inner end faces of the wire clamp cover 11 and the locking inner end faces of the wire clamp body 12.
[0067] The current situation is like Figure 7As shown, the drilling device 4 is then started, and while the rotating drilling bit 41 passes through the bushing plate 23, the pin hole of the wire clamp is formed at one time at the drilling point position of the wire clamp 1.
[0068] After the machining and forming, the drilling bit 41 returns to its original position. Under the action of the power unit 33, the push rod 331 contracts. Without the pushing force of the pushing block 332, the outer rotating push plate 321 returns to its original position under the action of the reset mechanism 34, that is, it returns to the "clamping state".
[0069] On the basis of the advantages of the specific embodiment 1, this embodiment also has the following advantages:
[0070] The device structure applied in this embodiment is simply designed, easy to implement, extremely low in cost, highly practical, and has created considerable economic benefits for the enterprise.

[0075] Below the inner push plate 311 in this embodiment, there is a sliding cushion block 312 for supporting the inner push plate 311. The sliding cushion block 312 is fixedly installed on the bottom plate 51 that is integrally fixed with the workbench 42 of the drilling device 4. The sliding cushion block 312 plays a supporting role and has a smooth surface. The design of the sliding cushion block 312 is to prevent the inner push plate 311 from sagging under the action of gravity for a long time. The intermediate clamping rod 21 is fixed on the bottom plate 51. The intermediate clamping rod 21 is fixed to the bottom plate 51 by a detachable structure such as bolts, and different sizes of intermediate clamping rods 21 can be adjusted and replaced according to the processing of different types of wire clamps. The outer rotating push plate 321 is sleeved on the rotating shaft 323 fixed on the bottom plate 51 and rotates around the rotating shaft 323. The reset mechanism 34 includes a tension spring 341. One end of the tension spring 341 is fixedly connected to the end of the outer rotating push plate 321 where an interference-free hollow groove 322 is opened, and the other end of the tension spring 341 is fixedly connected to the fixed column 342 fixed on the bottom plate 51.
[0076] The number of rotating shafts 323 in this embodiment is N, and N≥1.
