Description

Technical Field

[0001] This utility model relates to the field of disassembly tools, specifically to a high-efficiency, non-destructive disassembly tool for clamps. Background Technology

[0002] In the modern bottle-making industry, the bottle-making machine, as a core production equipment, plays a decisive role in production efficiency and product quality through its efficient and stable operation. The initial mold clamp and the final mold clamp, as key tooling components of the bottle-making machine, respectively undertake the important functions of positioning and forming the bottle's initial shape and final demolding. However, the bottle-making production site is a harsh environment with high temperatures (glass melting temperature can reach 1200℃) and abundant oil fumes, and the equipment needs to operate continuously for extended periods. Under these conditions, coke deposits easily accumulate on the surface of the machinery. Specifically, the bottle-making machine's lubricating oil evaporates at high temperatures, mixing with glass dust and mechanical impurities to form stubborn grease. This grease gradually adheres to the contact points between the clamps and bearings, and over time, the grease acts like glue, firmly "sticking" the clamps and bearings together.

[0003] When changing production and replacing tooling components, disassembling the clamp becomes a major challenge. Currently, the industry commonly uses a heavy hammer to forcibly remove the clamp from the bearing. This method is not only inefficient and labor-intensive, but the heavy hammer approach is also a brutal method that can easily cause irreversible damage to the clamp, bearing, and surrounding precision components, leading to decreased equipment accuracy, shortened equipment lifespan, and increased maintenance costs. Furthermore, this method poses serious safety hazards. Operators may suffer injuries from impacts or other accidents due to improper force or tool slippage during the hammering process, threatening their personal safety. Utility Model Content

[0004] The present invention aims to provide a special tool for disassembling clamps efficiently and without damage, addressing the problems of low efficiency and easy damage to equipment when disassembling clamps using existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This is a high-efficiency, non-destructive tool for disassembling clamps. It includes a connecting arm with a threaded sleeve fixed in the middle. A lead screw is threaded into the sleeve, with a conical head at the bottom and a drive unit connected to the top. Locating pins are connected to both ends of the connecting arm. The locating pins are used to insert into pin holes on the clamps, and the locating pins are equipped with connecting components for connecting with the clamps.

[0007] Preferably, as an improvement, the connecting component includes a connecting pin hole at the bottom end of the locating pin and a connecting pin that can be inserted into the connecting pin hole.

[0008] Preferably, as an improvement, the drive unit includes an electric drill, a sleeve is connected to the output shaft of the electric drill, and a nut for connecting to the sleeve is fixed to the top of the lead screw.

[0009] Preferably, as an improvement, the locating pin is detachably connected to the connecting arm.

[0010] Preferably, as an improvement, a connecting sleeve is fixed to the top of the locating pin, and the locating pin is sleeved onto the connecting arm through the connecting sleeve.

[0011] Preferably, as an improvement, the drive element includes a handle fixed to the top of the lead screw.

[0012] Preferably, as an improvement, a connecting bracket is provided at the top of the connecting arm, and a nut is provided in the middle of the connecting bracket. The nut is located above the threaded sleeve and the nut is aligned with the axis of the threaded sleeve in the vertical direction.

[0013] The principles and beneficial effects of this solution are as follows:

[0014] 1. In practical application, the positioning pin is inserted into the pin hole at the top of the clamp and fixed with the connecting pin, achieving precise positioning and secure connection of the clamp, completely restricting the clamp's horizontal movement and rotational freedom. The bottom end of the lead screw is pressed against the shaft hole of the bearing connected to the clamp's shaft. When the lead screw is driven to rotate, because it is pressed against the bearing, it can only rotate in place. The nut then converts the lead screw's rotational motion into a combined action of rotation and vertical movement of the connecting arm. The connecting arm, connected to the clamp by the fixing pin, restricts the free rotation end. Therefore, the connecting arm can move the clamp upwards along the lead screw, thereby removing the clamp. Using this solution to disassemble the clamp is not only efficient and simple, but also avoids the damage to the clamp, bearing, and surrounding components caused by traditional forceful disassembly. It effectively protects the precision structure of the equipment, extends its service life, and reduces the company's equipment maintenance costs; it also avoids the risks caused by forceful disassembly.

[0015] 2. A nut aligned with the axis of the threaded sleeve is added to the top of the connecting arm, forming a double-nut constraint structure for the lead screw. This significantly improves the stability of the lead screw during movement, allowing the force generated during lead screw rotation to be transmitted more evenly and stably to the connecting arm and clamp, ensuring a smooth disassembly process and enhancing the overall structural strength and reliability of the tool.

[0016] 3. The clamp is connected using a connecting assembly that mates with the connecting pin at the bottom of the locating pin. This design is simple and easy to operate. Operators can quickly connect and disconnect the locating pin from the clamp, significantly reducing preparation time.

[0017] 4. The drive unit offers two options: a handle and an electric drill. The handle provides flexible operation, facilitating precise control of the lead screw rotation in various spatial environments. The electric drill, through the engagement of a sleeve and the nut at the top of the lead screw, can quickly output high torque, which is more labor-saving and efficient than manual operation, significantly improving the efficiency of clamp disassembly and meeting disassembly needs under different working conditions.

[0018] 5. The locating pin and connecting arm feature a detachable connection design. Installation is achieved through an interference fit between the locating pin's top connecting sleeve and the connecting arm. This allows for quick adjustment of the locating pin's position or replacement with a corresponding locating pin, based on the pin hole size of different specifications and models of clamps. This makes the solution compatible with various clamps, effectively expanding the tool's applicability. Attached Figure Description

[0022] Figure 4 This is a top view of the clamp in an embodiment of the present invention. Detailed Implementation

[0023] The following detailed description illustrates the specific implementation method:

[0024] The reference numerals in the accompanying drawings include: connecting arm 1, threaded sleeve 2, lead screw 3, nut 4, handle 41, positioning pin 5, connecting sleeve 51, connecting pin hole 52, connecting bracket 6, nut 61, clamp 7, pin hole 71, bearing 8, and shaft hole 81.

[0025] Example 1:

[0026] like Figure 1 As shown, the high-efficiency, non-destructive clamp disassembly tool includes a connecting arm 1. A threaded sleeve 2 is integrally formed in the middle of the connecting arm 1. A lead screw 3 is internally threaded onto the threaded sleeve 2. The bottom end of the lead screw 3 is a conical head. A drive component is connected to the top of the lead screw 3. In this embodiment, the drive component is an electric drill. A nut 4 is fixed to the top of the lead screw 3. The nut 4 is an internal hexagonal nut 4. A sleeve is connected to the output shaft of the electric drill. The connection between the electric drill and the lead screw 3 is achieved by connecting the sleeve and the nut 4.

[0027] The connecting arm 1 is connected to both ends with positioning pins 5. In this embodiment, the positioning pins 5 and the connecting arm 1 are detachably connected. Specifically, a connecting sleeve 51 is welded and fixed to the top of the positioning pin 5. The positioning pin 5 is sleeved on the connecting arm 1 through the connecting sleeve 51, and the connecting sleeve 51 and the connecting arm 1 are connected by an interference fit. The positioning pin 5 is used to insert into the pin hole 71 on the clamp 71. The positioning pin 5 is provided with a connecting component for connecting with the clamp 71. The connecting component includes a connecting pin hole 52 opened at the bottom end of the positioning pin 5 and a connecting pin that can be inserted into the connecting pin hole 52.

[0028] In practical applications, the two locating pins 5 are respectively from... Figure 4 Insert the pin holes 71 on the left and right sides of the top of the clamp 71 until the bottom end of the positioning pin 5 is completely through the pin hole 71. Insert the connecting pin into the connecting pin hole 52 at the bottom end of the positioning pin 5, ensuring that the connecting pin and the pin hole 71 are tightly fitted, thereby connecting the clamp 71 to the positioning pin 5.

[0029] Rotate the lead screw 3 so that the conical head at the bottom of the lead screw 3 aligns with the central bearing 81 of the clamp 71 and slowly screws it in until the conical head is fully against the inner wall of the central bearing 81, ensuring that the lead screw 3 and the clamp 71 are strictly coaxial. Align the sleeve on the output shaft of the electric drill with the internal hex nut 4 at the top of the lead screw 3 and apply appropriate pressure to fully insert the sleeve into the nut 4, ensuring a tight connection. Start the electric drill to drive the lead screw 3 to rotate. Since the lead screw 3 is engaged with the threaded sleeve 2 in the middle of the connecting arm 1, and the bottom of the lead screw 3 is pressed against the central bearing 81 and cannot move axially, the rotation of the lead screw 3 will be converted into the upward movement of the connecting arm 1. Driven by the electric drill, the connecting arm 1 drives the clamp 71 to move smoothly upward along the axis of the lead screw 3 through the positioning pin 5, thereby disassembling and removing the clamp 71.

[0030] The disassembly of clamp 71 using this embodiment is simple, requires little manual labor, and is highly efficient. Replacing clamp 71 using the traditional method takes 20 minutes, while this solution can be completed within 10 minutes, greatly improving work efficiency.

[0031] Example 2:

[0032] like Figure 2 As shown, the difference between this embodiment and embodiment 1 is that the driving component is a handle 41 welded and fixed to the top of the lead screw 3. Holding the handle 41 and manually driving the lead screw 3 to rotate can also disassemble the clamp 71, which is suitable for use in the absence of power.

[0033] Example 3:

[0034] like Figure 3As shown, the difference between this embodiment and embodiment 2 is that an n-shaped connecting frame 6 is welded to the top of the connecting arm 1, and a nut 61 is welded to the middle of the connecting frame 6. The nut 61 is located above the threaded sleeve 2 and the axis of the nut 61 is aligned vertically with the axis of the threaded sleeve 2. The positioning pins 5 are directly welded and fixed to the bottom of both ends of the connecting arm 1. The addition of the nut 61 can improve the stability of the movement of the lead screw 3 and the overall structural strength of the device.
