Description

Technical Field

[0001] The invention relates to the technical field of electrical connector riveting equipment, and in particular to a special tool for riveting heavy-duty connector locking plate buckles. Background Art

[0002] Riveting is a process of firmly connecting two or more workpieces (such as wall panels) together by using rivets. This connection method is fast, strong, durable, vibration-resistant, and fatigue-resistant.

[0003] The riveting process generally includes: drilling holes in the workpiece, inserting rivets into the holes, fixing the rivets with a top die, and punching and forming the rivets by machine tools or manually.

[0004] In the manufacturing process of heavy-duty electrical connectors, the fixing of the shell locking plate buckle is separated from the rivet installation. Traditionally, this work mainly relies on manual riveting. However, due to the differences in the skill levels of operators, the riveting quality is often difficult to effectively guarantee, and the labor intensity is high and the efficiency is low.

[0005] In addition, the existing machine tool riveting process lacks the rivet positioning and pre-pressing link. At present, the material is usually fed and positioned manually, and then the punch press directly performs punching and riveting. This operation method easily causes the rivet to crack or expand before it accurately enters the rivet hole of the workpiece, which seriously affects the molding effect of the product. In addition, due to the inconsistency of manual positioning, the accuracy and uniformity of each positioning are difficult to guarantee, which not only affects the product quality, but also increases the safety risk during the operation process, and may cause personal injury if not carefully.

[0006] Therefore, it is necessary to transform the existing heavy-duty connector riveting process and develop a tooling with rivet positioning and pre-pressing function to ensure that the rivets can be accurately and stably positioned on the workpiece before stamping, so as to improve the product riveting quality, reduce labor intensity, improve production efficiency, and ensure the safety of operators. Utility Model Content

[0007] In view of the problems existing in the above-mentioned prior art, the utility model proposes a special tool for riveting locking plate buckles of heavy-duty connectors which has a simple and reasonable structure, convenient operation, high working efficiency and stable riveting quality.

[0008] The above-mentioned purpose of the utility model is achieved through the following technical solutions:

[0009] A special tool for riveting heavy-duty connector locking plate buckles, comprising: a machine base, an anvil, a punch pad, a pressure rod, a push-out assembly, and a driving mechanism. The anvil is fixed on the machine base, and the punch pad is located above the anvil; the punch pad is movably connected to one end of the pressure rod, the middle part of the pressure rod is movably connected to a pressure rod support fixed on the anvil, and the other end is movably connected to the upper end of the push-out assembly; the lower end of the push rod assembly is drivingly connected to the driving mechanism, and the driving mechanism is fixed on the machine base. The driving mechanism is used to push the push rod assembly to move upward, so that the punch pad end of the pressure rod moves downward to press the rivet onto the top of the anvil.

[0010] The driving mechanism comprises a cam and a cam handle; the cam handle is fixedly connected to the cam, the cam is movably connected to the machine base via a rotating shaft, the cam is drivingly connected to the push rod assembly, and the circumferential surface of the cam is in conflict with the lower end surface of the push rod assembly.

[0011] The cam is an equilateral triangle structure with rounded corners.

[0012] The push rod assembly is an adjustable push rod assembly, which includes an adjustment mechanism and a locking mechanism. The adjustment mechanism includes a push rod and a push rod seat; the upper end of the push rod is threadedly connected to the push rod seat, the upper end of the push rod seat is movably connected to one end of the pressure rod, and the lower end of the push rod is drivingly connected to the driving mechanism. The push rod is screwed in or out of the push rod seat to adjust the upward and downward movement of the push rod seat, thereby accurately adjusting the gap between the punch pad and the lower anvil to ensure that the rivet pre-pressing contact is tight.

[0013] The push rod seat is provided with a threaded through hole, and the locking mechanism is a locking bolt, which is adapted to the threaded through hole on the push rod seat. The upper end of the push rod can be fixed on the push rod seat by rotating the locking bolt.

[0014] The locking mechanism is a locking nut, which is threadedly connected to the upper end of the push rod. The upper end of the push rod can be fixed on the push rod seat by rotating the locking nut.

[0015] A support assembly is provided at a corresponding position below the punch pad, the support assembly is located below the anvil, and is mounted on the machine base; the support assembly includes a support member, a support elastic member, and a support base; a slide groove is provided on the support base, and the support member can slide up and down in the slide groove; the lower end surface of the support member abuts against the upper end surface of the support elastic member, and the lower end surface of the support elastic member abuts against the bottom surface of the slide groove of the support base. A limit hole is provided on the support base, and a limit pin is movably provided in the limit hole, and the other end of the limit pin is fixed in the support member.

[0016] The riveting device also includes a reset elastic member, which is arranged between the pressure rod and the pressure rod support, with its upper end surface tightly against the lower end surface of the pressure rod, and its lower end surface tightly against the upper end surface of the anvil.

[0017] A rivet positioning protrusion adapted to the rivet end surface depression is provided at the position of the anvil corresponding to the punch pad. The rivet positioning protrusion is a conical protrusion.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. An adjustable ejector assembly is set to adjust the gap between the punch pad and the anvil, ensuring high-quality riveting effect and preventing the rivet from being loosely pressed. At the same time, it is suitable for riveting workpieces of different thicknesses, expanding the scope of application.

[0020] 2. The support assembly with compensation function can compensate for the riveting deformation gap, avoid deformation and cracking of the workpiece, and improve the yield rate; it can also cooperate with the ejector assembly to adjust the punch and the anvil to effectively eliminate the rivet gap and ensure that there is no gap defect between the rivet and the workpiece after riveting; and further expand the scope of application.

[0021] 3. High safety. When the riveting tool is closed, the punch pad presses the rivet tightly, so that the component to be riveted is stably fixed on the riveting tool. During the riveting process, the operator does not need to support or press the material, thus avoiding mechanical injuries caused by misoperation.

[0022] 4. Precise control. Due to direct manual operation, the operator can more accurately control the force and speed during the riveting process, thereby improving the quality and accuracy of riveting.

[0023] 5. Low cost: No complex drive system and electrical control device are required, so the manufacturing cost is relatively low.

[0024] 6. The beneficial effects of using the utility model to position and pre-press rivets before punching rivets on a punch press are as follows:

[0025] First, rivet positioning preloading helps ensure that the rivet can be accurately placed in the predetermined position before riveting. Through preloading, the fit between the rivet and the workpiece can be checked in advance to ensure the alignment and accuracy of the rivet hole. This helps reduce errors in the riveting process and improve the quality of the riveting.

[0026] Secondly, preloading can also help reduce the cracking and expansion of rivets that may occur during the riveting process. Without preloading, direct riveting by punching may cause the rivet to crack and expand due to excessive pressure before it fully enters the rivet hole. By preloading, the pressure on the rivet can be gradually increased, allowing it to gradually adapt and smoothly enter the rivet hole, thereby reducing the risk of cracking and expansion.

[0027] In addition, rivet positioning pre-pressing can also improve the consistency and stability of riveting. Through pre-pressing, it can ensure that the position and state of the rivet are consistent before each riveting, thereby reducing variables and uncertainties during the operation. This helps to improve the stability and consistency of riveting and ensure the stability of product quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0038] Example 1 (see Figure 1 to Figure 4 ):

[0039] A special tool for riveting heavy-duty connector locking plate buckles, comprising:

[0040] The machine base 1 is used to install and fix various components of the riveting tooling, and to conveniently and reliably fix the tooling to the punching machine workbench to realize the punching and riveting of the workpiece.

[0041] The anvil 2 is used to provide positioning and support for the riveting of the workpiece, and to achieve the required deformation of the rivet tail during the riveting process.

[0042] The punch pad 3 is used to protect the punch and the rivet head, disperse the pressure, absorb the impact, ensure the stability of the riveting process and quality, and at the same time, is used to squeeze the rivet into the rivet hole of the workpiece so that the punch press can punch and rivet, and has a pre-punching effect.

[0043] The pressing rod 4 is used for the punch pad 3 to smoothly press the rivet or release the rivet.

[0044] The extension assembly 5 is used to push the pressure rod 4 to rotate under the drive of the driving mechanism 6, so that the punch pad can press the rivet or leave the rivet; it is also used to adjust the gap between the punch pad and the anvil to suit the pre-pressure of different workpieces and rivets.

[0045] The driving mechanism 6 is located below the ejector assembly and is used to drive the ejector assembly to move up and down, thereby achieving the rivet pressing of the punch pad 3;

[0046] The reset elastic member 4-1 is located between the pressure rod and the anvil, close to the pressure head pad side, and is used to drive the pressure head pad end of the push rod assembly to move upward so that the punch pad leaves the rivet; the reset elastic member 4-1 has a damping effect when the driving mechanism 6 drives the push rod assembly to move upward, so that the riveting of the pressure head pad is smoother and more uniform. When the driving mechanism 6 is a cam, the reset elastic member 4-1 can also ensure that the lower end surface of the push extension assembly 5 is always in close contact with the circumference of the cam, making the cam drive transmission more stable and reliable.

[0047] The anvil 2 is fixed on the machine base 1, and the pressure head pad 3 is located above the anvil 2; the pressure head pad 3 is movably connected to one end of the pressure rod 4, the middle part of the pressure rod 4 is movably connected to the pressure rod support 2-1 fixed on the anvil 2, and the other end is movably connected to the upper end of the extension component 5. The lower end of the extension component 5 is drivingly connected to the driving mechanism 6. The driving mechanism 6 is installed on the machine base 1.

[0048] The driving mechanism 6 includes a cam 6-1 and a cam handle 6-2, and the cam handle 6-2 is fixedly connected to the cam 6-1. The cam is connected to the machine base 1 through a rotating shaft. The circumference of the cam 6-1 contacts the lower end surface of the top extension assembly. The rotating cam can drive the top extension assembly 5 to move up and down, thereby causing one end of the pressure rod 4 to move up and the other end to press down, thereby driving the pressure head pad 3 to press the rivet into the rivet hole of the workpiece so that the punch press can officially rivet.

[0049] During the entire process of using the tooling, the positioning and locking of the rivet on the workpiece can be completed by operating the cam handle, without the need for manual positioning and adjustment. It is quick, convenient and efficient.

[0050] See also Figure 4 , Figure 5 The cam 6-1 adopts a co-rounded equilateral triangle structure, which improves the stability and force balance of the rivet positioning pre-pressing process through linear trajectory and co-circular transition.

[0051] Compared with the traditional eccentric cam structure, it has the advantages of simple processing (only three equiangular planes need to be milled on the circumferential surface to form it, without the need for eccentric cam curve milling), smooth and uniform movement (rounded corners and equilateral structure, forming a linear pre-loaded rivet, and the whole process is balanced (equivalent to the hydraulic effect), making its movement trajectory smoother, avoiding the sudden change and impact of conventional arc cams, and the problem that the stress concentration at the tail of the rivet is easy to crack and it is not easy to enter the rivet hole and affect the riveting quality. At the same time, it also reduces mechanical vibration and noise, and has the advantages of low noise, low impact and long life.

[0052] 5. The cam of the driving mechanism adopts a common rounded equilateral triangle structure (the conventional cam is an arc track, with stress concentration and sudden changes, and large impact). It has the advantages of simple processing, smooth and uniform movement, low noise, small impact and long service life.

[0053] Embodiment 2:

[0054] Different from the above-mentioned embodiment, in this embodiment, a servo motor is used to rotate the cam, thereby driving the extension assembly to work, which has the advantage of improving the degree of automation.

[0055] Embodiment 3:

[0056] Different from the above-mentioned embodiment, the driving mechanism of this embodiment is a cylinder, and the extension assembly 5 is a piston rod, whose upper end is movably connected to the pressure rod 4. When the cylinder pushes the piston, the piston rod can move upward, so that one end of the pressure rod moves upward, and then drives the pressure head pad 3 at the other end to press down, so as to achieve the purpose of pressing the rivet on the workpiece. Compared with the previous example, this structure realizes automatic positioning pre-pressing, and the consistency is relatively good.

[0057] Example 4 (see Figure 1 , Figure 5 , Figure 6 )

[0058] Different from the above-mentioned embodiment, the push rod assembly 5 of this embodiment is an adjustable push rod assembly, which is used to flexibly adjust the push extension height so as to produce different pressure head forces and downward pressure gaps to meet the riveting requirements of different workpieces. This adjustable push rod assembly 5 includes an adjustment mechanism and a locking mechanism. The adjustment mechanism includes a push rod 5-1 and a push rod seat 5-2; the upper end of the push rod 5-1 is threadedly connected to the push rod seat 5-2, the upper end of the push rod seat 5-2 is movably connected to one end of the pressure rod 4, and the lower end of the push rod 5-1 is drivingly connected to the driving mechanism 6.

[0059] See also Figure 5 The locking mechanism is a locking bolt 5-3, which can lock or loosen the push rod 5-1 through the threaded through hole on the push rod seat 5-2, so that the push rod 5-1 penetrates into or retracts into the threaded through hole of the push rod seat 5-2 to adjust the length of the entire push rod assembly, and then adjust the gap between the punch pad and the anvil.

[0060] See also Figure 6 The locking mechanism can also be a nut 5-4, which is threadedly sleeved on the top rod 5-1. By rotating the locking nut, the upper end of the top rod 5-1 can be self-lockingly fixed on the top rod seat 5-2. Compared with the locking mechanism of the locking bolt 5-3, the locking nut locking mechanism does not need to open a threaded through hole on the top rod seat, and has the advantages of simple structure, low cost, and no damage to the top rod seat.

[0061] The gap between the punch pad and the anvil is designed to be adjustable, which mainly has the following functions:

[0062] (1) Adapt to workpieces of different thicknesses: By adjusting the gap between the punch pad and the anvil, it can adapt to workpieces of different thicknesses. In this way, the tooling can perform riveting operations on workpieces of various specifications, improving the flexibility and versatility of the tooling. (2) Control the riveting depth: The size of the gap directly affects the impact depth of the punch on the workpiece during the riveting process. By adjusting the gap, the riveting depth can be accurately controlled to ensure that the riveting quality meets the process requirements. (3) Reduce impact damage: If the gap is too small, the impact of the punch on the workpiece will be too severe, which may cause damage or deformation of the workpiece. By adjusting the gap, the impact force can be reduced and the risk of damage to the workpiece can be reduced. (4) Optimize the riveting effect: The appropriate gap helps to form a good riveting effect, including the formation of the rivet, the connection strength and the appearance quality. (5) Maintain equipment safety: Too large a gap may cause improper contact between the punch and the workpiece, causing equipment damage or operating errors. Therefore, the adjustment of the gap also helps to maintain the safety and stability of the equipment. Therefore, the adjustability of the gap between the punch pad and the anvil provides more flexibility and control for the riveting operation, helping to achieve high-quality riveting results and protect equipment safety.

[0063] Example 5 (see Figure 1 , Figure 2 , Figure 8 )

[0064] On the basis of the above-mentioned embodiment, a support assembly 7 is provided at a corresponding position below the punch pad 3 of the present embodiment, which is used to further eliminate the rivet gap and provide support for the workpiece shell in the material for riveting operation. The support assembly 7 is installed on the machine base 1, close to the position below the anvil 2. The support assembly 7 includes a support member 7-1, a support elastic member 7-2, and a support base 7-3. A slide groove is provided on the support base 7-3, and the support member 7-1 can slide up and down in the slide groove. The lower end surface of the support member 7-1 is against the upper end surface of the support elastic member 7-2, and the lower end surface of the support elastic member 7-2 is against the bottom surface of the slide groove of the support base 7-3.

[0065] The function of the support assembly 7 is: when the riveting tool is in the closed state, the support member 7-1 pushes the workpiece shell upward under the elastic force of the elastic member 7-2, and at the same time, the rivet step surface is closely contacted with the workpiece shell under the downward pressure of the punch pad 3. In this way, when the machine tool is riveted, it can further ensure that the rivet is perfectly riveted with the workpiece shell, thereby avoiding the occurrence of gap defects after riveting.

[0066] Secondly, when the rivet is punched and riveted, the rivet will be deformed by the punching action of the punch press, and its axial length will be shortened by 0.3mm to 0.5mm. Since the shell material of the riveted workpiece is usually zinc alloy or aluminum alloy, the shell is prone to dents or cracks when it is subjected to greater extrusion. In order to solve this problem, the support member supporting the workpiece shell on the riveting tool is designed as a movable structure with an elastic member. In this way, when the workpiece shell is squeezed by a greater force, the workpiece shell will push the support member, thereby compressing the supporting elastic member under the support member. In this way, before the shell is deformed, the axial shortening distance that occurs when the rivet is riveted is absorbed and compensated by the compression of the supporting elastic member. In this way, not only is the reliable riveting of the rivet ensured, but also the deformation and / or rupture of the relatively fragile workpiece shell is avoided.

[0067] Example 6 (see Figure 1 to Figure 4 )

[0068] On the basis of the above-mentioned embodiment, the present embodiment is to set an elastic member 4-1 between the pressure rod 4 and the pressure rod support 2-1, the upper end face of which is tightly against the lower end face of the pressure rod 4, and the lower end face of which is tightly against the upper end face of the anvil 2, so as to ensure that the cam of the driving mechanism is always in close contact with the push rod, and prevent the occurrence of a gap phenomenon. At the same time, it plays a booster and damping role to stabilize and increase the driving force, ensure that the driving mechanism and the push-up assembly are tightly against each other, and stably transmit power. When the cam rotates to the open position, the reset elastic member 7 will extend, push the pressure rod 4, and make the pressure head pad leave the rivet to replace the workpiece; at the same time, the pressure rod 4 rotates clockwise, so that the push-up assembly is always in close contact with the cam profile surface. When the cam rotates to the closed position, the push-up assembly 5 pushes the pressure rod 4 to rotate counterclockwise, driving the punch pad to press the rivet down; at this time, due to the damping effect of the elastic member, the punch pad is pressed down slowly and steadily, so that the rivet tail is subjected to a balanced force, avoiding cracking, affecting positioning and entering the rivet hole of the workpiece. It helps to accelerate the departure when opening, and plays a damping and stabilizing role when closing, giving the operator a comfortable and stable feel.

[0069] Example 7 (see Figure 1 , Figure 6 ),

[0070] On the basis of the above-mentioned embodiments, the present embodiment is provided with a rivet positioning protrusion 2-2 matching the rivet end face depression at the position of the punch pad on the anvil 2, which is used for accurate positioning and pre-riveting of the rivet, ensuring the correct completion of the machine tool punching and riveting and the perfect riveting effect. At the same time, it also ensures the consistency of riveting of different workpieces.

[0071] Rivet positioning and pre-riveting process of riveting tooling (refer to Figures 1 to 4 ): (the hand resistance increases and there is a clicking sound)

[0072] 1. First, when the cam handle is rotated 60° outward (see Figure 1 , Figure 3 ), the riveting tool is in the open state. In the open state, the low point of the cam (rounded triangle cam plane) faces the ejector rod, and under the elastic force of the reset elastic member, the ejector rod moves down and the punch pad is lifted. At this time, there is enough space between the punch pad and the lower anvil to facilitate the loading or unloading of workpiece materials.

[0073] 2. Load the workpiece material to be riveted into the tooling according to the position (dummy outline) in the figure. Check whether the workpiece shell is placed on the support of the riveting tooling and whether the rivet depression is aligned with the top of the anvil (rivet positioning protrusion).

[0074] 3. After the workpiece housing assembly is loaded into the riveting fixture, pull the rotating cam handle → the cam circumferential surface (diameter increases) forces the push rod to move up → push the pressure rod (the pressure rod rotates counterclockwise with the pressure rod support as the axis), overcome the elastic force of the reset spring 7 → the other end of the pressure rod is lowered → the punch pad is lowered → continue to rotate the cam handle until the push rod touches the cam circumferential surface → press the rivet on the top of the anvil. This state is the closed state of the riveting fixture. (See Figure 2 , Figure 4 )

[0075] 4. Continue to rotate the cam handle to a vertical position so that the rivet is fully and steadily pressed against the top of the anvil.

[0076] 5. The cam handle is in a vertical state. After the punch pad presses the rivet, the punch press can be operated to perform the riveting operation and rivet the rivet to the workpiece shell.
