Description

Technical Field

[0001] This invention relates to the field of gasket installation tools, specifically a clamping gasket installation tool. Background Technology

[0002] Clamping gaskets are widely used in current automobile manufacturing processes, but they can cause problems such as difficulty in clamping when installed manually, long working time, and hand injury from prolonged assembly at the workstation.

[0003] Currently, there are no operating tools for semi-automatic installation of clamping gaskets on the market. After searching, no semi-automatic gasket installation tools were found. Most tools are still for manual installation or are for fully automatic installation production lines. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a clamping gasket installation tool.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping washer installation tool, comprising:

[0006] Housing and handle for handheld operation;

[0007] The housing contains a striking unit and a feeding unit;

[0008] The striking unit includes a striking rod and a driving part that drives the striking rod to strike forward. The striking rod is connected to a spring. The driving part is used to drive the striking rod to slide backward to compress the spring. After being compressed to the limit, the driving part releases the sliding limit of the striking rod, and the potential energy of the spring is released, so that the striking rod strikes forward.

[0009] The feeding unit includes a material box and a feeding ring located at the material box outlet. The feeding ring is connected to the striking rod via a rocker arm. When the striking rod slides, the feeding ring is driven to move via the rocker arm. During its movement, the feeding ring pushes the pad in the material box to the front end of the striking rod.

[0010] Preferably, the driving part is a rotating column of a motor. The rotating column has a hollow structure and a slide rod is provided inside the rotating column. The striking rod is slidably connected to the slide rod, and the rotating column is sleeved on the outer peripheral surface of the striking rod. The outer peripheral surface of the striking rod is provided with a cam groove and a straight groove communicating with the cam groove. A protruding post is installed on the inner wall of the rotating column. When the protruding post is accommodated in the cam groove, the rotating column rotates. Under the limitation of the cam groove, the striking rod is driven to slide back and forth. At the end of one stroke, the protruding post enters the straight groove, and the straight groove is set along the direction of the spring force.

[0011] Preferably, the striking rod consists of two separate parts: a striking post and a power post. A cam groove and a straight groove are provided on the power post, which is driven. The striking post is located at the front end of the power post. When the power post is impacted by the potential energy of the spring, the impact force is transmitted to the striking post, which pushes the pad out.

[0012] Preferably, it also includes a balance column, which is located at the end of the power column away from the striking column. The balance column has the same structure as the power column and is slidably connected to the slide rod. The cam groove of the balance column is opposite in direction to the cam groove of the power column, that is, when the rotating column rotates, the balance column and the power column slide towards each other.

[0013] Preferably, the first section of the rocker arm is hinged to the striking rod, the middle section of the rocker arm is hinged to the housing, and the other end of the rocker arm is hinged to the feeding ring. The feeding ring is located at the lower part of the striking rod. When the striking rod slides backward, the feeding ring is lifted upward under the drive of the rocker arm.

[0014] Preferably, a hopper ring is provided on one side of the feeding ring, the hopper ring is located at the output port end of the hopper, the hopper ring is provided with a material blocking groove, a locking ring is provided around the hopper ring, and a protruding material blocking block is provided on the inner side wall of the locking ring. The material blocking block is accommodated in the material blocking groove and protrudes from the inner wall of the hopper ring. Under normal conditions, a push spring is installed on the side of the hopper away from the output port end, which pushes the internal gasket toward the output port end and abuts against the side of the material blocking block.

[0015] A locking block is connected to the bottom of the locking ring. The locking block is located below the feeding ring. When the feeding ring falls, it presses down on the locking block, and the locking ring moves downward under force. The blocking block is displaced, releasing the obstruction to the gasket.

[0016] The locking ring is made of elastic material. When the feeding ring moves upward, the locking ring returns to its original position and blocks the gasket again.

[0017] Preferably, the locking block at the bottom of the locking ring is slidably connected to the locking ring. When it slides to the front limit position, it is pressed down by the feeding ring, and when it slides to the rear limit position, it is not pressed down by the feeding ring.

[0018] Preferably, the cassette opening ring is fixedly installed on the housing, and a pressure plate is provided on the side of the cassette opening ring near the cassette. A baffle plate is provided on the outer wall of the cassette near the cassette opening ring. The baffle plate protrudes from the inner wall of the cassette and is used to block the gasket. The side wall of the baffle plate near the cassette opening ring has an arc-shaped or inclined structure. After feeding, the cassette is pressed against the cassette opening ring. The pressure plate generates a radial outward force on the baffle plate, so the baffle plate retracts. The gasket can then pass through the baffle plate and reach the cassette opening ring until it reaches the baffle block of the locking ring.

[0019] Preferably, the rotating column has a gear structure, the motor is located at the bottom of the rotating column, and the output end of the motor is a pinion that meshes with the rotating column.

[0020] This invention features a drive unit that drives a striking rod to install gaskets by striking them, and utilizes the displacement of the striking rod to drive a feeding ring for feeding, thus achieving a semi-automated gasket installation function and improving work efficiency.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please refer to the attached diagram for a clamping washer installation tool. Figure 1 As shown, this embodiment aims to design a user-friendly tool that enables semi-automatic installation of gaskets.

[0031] This embodiment is designed as follows: Figure 1 The gun's structure.

[0032] It includes a housing 1 and a handle 2 mounted under the housing 1.

[0033] Its cross-sectional structure and internal structure disassembly diagram are shown in the reference diagram. Figure 2 as well as Figure 3 As shown.

[0034] The specific functional implementation includes the striking unit and the feeding unit.

[0035] The striking unit includes a striking rod and a driving part that drives the striking rod to strike forward. The striking rod is connected to a spring. The driving part is used to drive the striking rod to slide backward to compress the spring. After being compressed to the limit, the driving part releases the sliding limit of the striking rod, and the potential energy of the spring is released, causing the striking rod to strike forward.

[0036] Reference Figure 2 , Figure 4 as well as Figure 5 As shown; the driving part is a rotating column 31 driven by motor 3. The rotating column 31 has a hollow structure and a slide rod 310 is provided inside the rotating column 31. The striking rod is slidably connected to the slide rod 310, and the rotating column 31 is sleeved on the outer peripheral surface of the striking rod. The outer peripheral surface of the striking rod is provided with a cam groove and a straight groove communicating with the cam groove. A protruding post 311 is installed on the inner wall of the rotating column 31. When the protruding post 311 is accommodated in the cam groove, the rotating column rotates. Under the limit of the cam groove, the striking rod is driven to slide back and forth. At the end of one stroke, the protruding post 311 enters the straight groove, which is set along the direction of the spring force.

[0037] Reference Figure 2 As shown, the striking rod consists of two separate parts: a striking post 34 and a power post 33. A cam groove 330 and a straight groove 331 are provided on the power post. The power post 33 is driven. The striking post 34 is located at the front end of the power post 33. When the power post 33 is impacted by the potential energy of the spring, the impact force is transmitted to the striking post 34, and the striking post 34 pushes out the pad.

[0038] Reference Figure 5 as well as Figure 6 As shown, both ends of the straight groove 331 and the cam groove 330 are connected. In the initial state, the protrusion 311 of the power column 33 is located at one end of the two grooves. When the rotating column 31 rotates, the protrusion 311 enters the cam groove 330. Under the limit of the cam groove 330, it pushes the power column 33 to slide. When the rotation limit is reached, that is, when the protrusion 311 reaches the hinge point at the other end of the two grooves, the protrusion 311 enters the straight groove 331. As shown in the figure, the axial limit of the power column 33 by the protrusion 311 in the straight groove 331 is released. Under the action of the spring (the direction of the spring force is consistent with the extension direction of the straight groove 331), the power column 33 slides back to the initial state.

[0039] Furthermore, a conical spring 300 is provided at the connection of the striking post 34. One force-bearing end of the conical spring 300 contacts the housing, and the other force-bearing end contacts the striking post 34. A cylindrical spring is installed at the rear end of the power post 33. One force-bearing end of the spring contacts the power post 33, and the other force-bearing end contacts the slide rod 3 or the contact surface structure inside the housing.

[0040] During operation, the power column 33 strikes the striking column 34 forward under the action of its rear-end spring, compressing the conical spring 300 during the forward striking process. After one strike is completed, the rotating column 31 rotates, causing the power column 31 to retract, while the striking column 34 retracts under the action of the conical spring 300 and comes into contact with the power column 33.

[0041] The conical spring 300 also helps to reduce the impact of the striking post 34 on the housing.

[0042] The advantage of this split striking rod is that it facilitates parts replacement. For example, if the cam groove wears out due to prolonged use, affecting its operation, a one-piece structure would require replacing the entire rod, while a split structure only requires replacing the power column 31, saving costs.

[0043] Continue to refer to Figures 2-6 As shown, in a preferred embodiment, a balance column 35 is also provided at the end of the rotating column 31 away from the power column 33. The structure of the balance column 35 is the same as that of the power column 33, except that the cam groove of the balance column 35 is in the opposite direction to the cam groove of the power column 33. That is, when the rotating column 31 rotates, the cam grooves of both columns limit their movement, causing them to slide in opposite directions.

[0044] like Figure 2 As shown, in the design of the balance column 35, the spring that drives the power column 33 to strike forward is positioned between the balance column 35 and the power column 33, which is the cylindrical spring 301 in the figure. Then, another spring 302 is added at the rear end of the balance column 35 to help the balance column 35 return to its original position.

[0045] In actual operation, the rotating column 31 rotates, the power column 33 retracts, and the balance column 35 moves forward. The two compress the cylindrical spring 301 in the middle. After reaching the limit state, the protrusions of the rotating column 31 in the power column 33 and the balance column 35 enter the straight groove, and the two columns slide towards each other.

[0046] The function of the balance column 35 is to maintain the operational balance of the drive system of the rotating column 31. Since the rotating column 31 is installed inside the housing, if only one end of the rotating column 31 is subjected to force, its structure will inevitably shift over time. The addition of the balance column 35, with its convex columns at both ends for driving, ensures that the force is distributed evenly, maintaining balance. Simultaneously, the movement of the balance column 35 can also help to neutralize the impact of the power column 33 on the housing.

[0047] Continue to refer to Figures 6-8 As shown, the feeding unit is linked to the striking unit through the rocker arm 5 structure.

[0048] The first section of the rocker arm 5 is hinged to the striking rod (point C in the figure), the middle section of the rocker arm 5 is hinged to the housing (point A in the figure), and the other end of the rocker arm is hinged to the feeding ring 7 (point B in the figure). The feeding ring 7 is located at the lower part of the striking rod. When the striking rod slides backward, driven by the rocker arm 5, the feeding ring 7 is lifted upward, feeding the shim inside the feeding ring 7 into it through the feeding groove 40 of the striking ring 4. Figure 4 As shown, the striking ring 4 is installed inside the housing and is located on the inner edge of the mounting opening 01. The striking rod performs the striking action within the striking ring 4.

[0049] It's worth noting that, because the joystick 5 has a fast response time, to prevent the feeding ring 7 from falling too quickly when the striking rod strikes forward, causing the pad to fall prematurely and not be struck, the travel of both joysticks must be carefully designed during implementation to ensure that they are struck.

[0050] Reference Figure 7 As shown, a box mouth ring 9 is provided on one side of the feeding ring 7. The box mouth ring 9 is located at the output port end of the box 8. A material blocking groove 91 is provided on the box mouth ring 9. A locking ring 6 is sleeved around the box mouth ring 9. A protruding material blocking block 61 is provided on the inner side wall of the locking ring 6. The material blocking block 61 is accommodated in the material blocking groove 91 and protrudes from the inner wall of the box mouth ring 9. Under normal conditions, a pushing spring 84 is installed on the side of the box 8 away from the output port end. Through the push plate 83 at the end, the internal gasket is pushed towards the output port end and pressed against the side of the material blocking block 61.

[0051] A locking block 101 is connected to the bottom of the locking ring 6. The locking block 101 is located below the feeding ring 7. When the feeding ring 7 falls, it presses down on the locking block 101, causing the locking ring 6 to move downwards under force. The stop block 61 is displaced, releasing its obstruction of the gasket. As shown in the figure, the locking ring 6 is a semi-circular structure with stop blocks 61 on both sides and at the bottom, corresponding to three stop grooves 91. Under normal conditions, the inner wall of the locking ring 6 is fitted and surrounds the outer perimeter of the cartridge ring 9. When pressed down, the side stop blocks 61, which are arc-shaped and normally accommodated in the stop grooves 91, are squeezed by the groove surface of the stop grooves 91, causing them to open at a certain angle. The stop blocks 61 then retract, thus no longer obstructing the gasket. The bottom stop block 61 is also pressed down and retracts.

[0052] The locking ring 6 is made of elastic material. When the feeding ring 7 moves upward, the locking ring 6 returns to its original position and blocks the gasket again.

[0053] The locking block 101 at the bottom of the locking ring 6 is slidably connected to the locking ring 6, such as... Figure 8As shown, a groove 102 is provided at the bottom of the locking ring 6, and the locking block 101 is slidably connected to the groove 102. A stop lever 10 is provided at the bottom of the locking block 101 for operation. When it slides to the front limit position, it is pressed down by the feeding ring 7; when it slides to the rear limit position, it is not pressed down by the feeding ring. That is to say, the stop lever 10 can control whether the shim will enter the feeding ring 7.

[0054] The cartridge opening ring 9 is fixedly mounted on the housing, and a pressure plate 92 is provided on the side of the cartridge opening ring 9 near the cartridge. A baffle plate 82 is provided on the outer wall of the cartridge 8 near the cartridge opening ring 9. The baffle plate 82 protrudes from the inner wall of the cartridge and is used to block the gasket. The side wall of the baffle plate 82 near the cartridge opening ring 9 has an arc-shaped or inclined structure. Additionally, as shown in the figure, the baffle plate 82 is located at the extended end of a spring piece 81 on the side of the cartridge 8. The baffle plate 82 is movable.

[0055] After feeding, the material box 8 is pressed forcefully towards the box opening ring 9. The pressure plate 92 exerts a radial outward force on the material stop plate 82, causing the material stop plate to retract. The gasket can then pass through the material stop plate 82 and reach the box opening ring 9, until it reaches the material stop block of the locking ring 9.

[0056] In addition, the rotating column 31 has a gear structure, and the motor 3 is located at the bottom of the rotating column 31. The output end of the motor 3 is a pinion 32, which meshes with the rotating column 31. The handle 2 is equipped with a button 20 for controlling the motor switch, and a battery for powering the motor 3 is also installed inside the handle.

[0057] During operation, motor 3 drives rotating column 31 to rotate, rotating column 31 drives power column 33 to retract to its limit state, power column 33 impacts striking column 34 under the action of spring, striking column 34 moves forward and strikes the pad, and then striking column 34 retracts under the action of conical spring 300 and continues to contact power column 33.

[0058] When the striking post 34 moves backward, end C of the rocker arm 5 moves backward, and end B of the rocker arm 5 rotates around point A, causing the feeding ring 7 to move upward and send the shim into the upper striking ring 4; when the striking post 34 strikes forward rapidly, the feeding ring 7 gradually falls, pressing down the locking ring 6, allowing the first shim to enter the upper striking ring 4. Waiting for the next working stroke.

[0059] During this process, the feeding can be controlled by the stop lever 10. For example, if the first gasket is not installed properly, the stop lever 10 can slide the locking block 101 to retract it, preventing it from being pressed down by the feeding ring 7. However, since there is already a gasket in the feeding ring 7, the second gasket can be installed normally. After the second gasket is installed, since no more material is being fed, the first gasket can be tapped again.

[0060] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
