Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting and hoisting tools, specifically a hoisting tool for a coupling machine tool. Background Technology
[0002] In the processing workshop for large workpieces, machine tool operators need to clamp the workpieces onto the chuck for machining. Lighter workpieces also require two people to move them up and down; heavier workpieces require the assistance of electric hoists and slings for moving. Each time a workpiece is hoisted, it must be secured with slings beforehand, and then lifted by a crane or hoist.
[0003] For example, a coupling lifting tool for a coupling threading machine, with announcement number "CN201027138Y", allows the adjusting rod to rotate around the pin shaft via an adjusting screw at the lower end of the lifting tool base during the assembly process. This makes the lifting rod vertically aligned with the lifting shaft, ensuring the lifted coupling blank is horizontal, facilitating loading and unloading of the coupling on the coupling threading machine. However, this coupling lifting tool for coupling threading machines requires significant physical effort from the operator to secure the workpiece to the lifting rod, increasing labor costs. Furthermore, when the workpiece is large, the contact area between the lifting rod and the workpiece is small, making it difficult to secure the workpiece and hindering the transport of larger workpieces, thus increasing operational limitations. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that when it is necessary to lift a workpiece, the operator usually needs to expend a lot of physical strength to tie the workpiece to the lifting rod, which consumes a lot of physical strength and increases the manual labor. At the same time, when the workpiece is large, the contact area between the lifting rod and the workpiece is small, which makes it impossible to fix the workpiece and thus cannot transport large workpieces, thereby increasing the limitations of the work. Therefore, a lifting tool for coupling machine tools is proposed.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] Design a lifting device for coupling machine tools, including a lifting ring, a lifting device body, and a lifting device load body. The lifting device body is fixedly connected to the lower part of the lifting ring, and the lifting device load body is fixedly connected to the lower left side of the lifting device body. The lifting device load body is provided with an adjustment mechanism inside, and anti-slip elastic rubber is installed on the outer side of the lifting device load body. An anti-detachment stop bar is provided on the left side of the lifting device load body, and an anti-detachment stop bar brake wrench is installed below the anti-detachment stop bar.
[0007] Preferably, the anti-disengagement lever brake wrench is machined with a fixing hole for the manual unlocking rope of the braking device.
[0008] Preferably, the adjusting mechanism includes a crossbar, a locking block fixedly connected to the left side of the crossbar, an mounting block fixedly connected to the left side of the crossbar, multiple threaded holes machined on the crossbar, the inner wall of the threaded holes being threadedly connected to bolts, the outer wall of the bolts being threadedly connected to the load body of the lifting device, and the outer walls of the crossbar and the locking block being slidably connected to the load body of the lifting device.
[0009] Preferably, an anti-disengagement bar is installed on the outer wall of the mounting block.
[0010] Preferably, the inner side of the bolt is pressed against the anti-slip elastic rubber.
[0011] The present invention provides a lifting device for a coupling machine tool, which has the following advantages: Through the cooperation of the lifting device's load body and the adjustment mechanism, the mounting block is pulled outwards. The movement of the mounting block causes the crossbar and locking block to slide along the inner wall of the lifting device's load body. When the mounting block moves to the desired position, the operator controls the anti-detachment lever brake wrench to bring the anti-detachment lever into contact with the workpiece. The operator then rotates the bolt, screwing it into the lifting device's load body and then into the threaded hole on the crossbar, thereby fixing the position of the mounting block. This allows for adjustment of the distance between the mounting block and the lifting device's load body, enabling the transport of workpieces with different through-hole lengths. This reduces work limitations and eliminates the need for operators to expend significant physical effort to bind the workpiece to the outside of the lifting device's load body, thus saving labor to a certain extent.

Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings:
[0020] See attached document Figure 1-6 In this embodiment, a lifting device for a coupling machine tool includes a lifting ring 1, a lifting device body 2, and a lifting device load body 8. The lifting device body 2 is fixedly connected to the lower part of the lifting ring 1, and the lifting device load body 8 is fixedly connected to the lower left side of the lifting device body 2. An adjustment mechanism 7 is provided inside the lifting device load body 8, and an anti-slip elastic rubber 3 is installed on the outer side of the lifting device load body 8. An anti-detachment stop bar 4 is provided on the left side of the lifting device load body 8, and an anti-detachment stop bar brake wrench 5 is installed below the anti-detachment stop bar 4.
[0021] The anti-disengagement lever brake wrench 5 is machined with a brake device manual unlocking rope fixing hole 6, the anti-disengagement lever 4 is installed on the outer wall of the mounting block 705, and the inner side of the bolt 704 is abutted against the anti-slip elastic rubber 3.
[0022] The adjusting mechanism 7 includes a crossbar 701, a locking block 703 fixedly connected to the left side of the crossbar 701, an mounting block 705 fixedly connected to the left side of the crossbar 701, and multiple threaded holes 702 machined on the crossbar 701. The inner wall of the threaded hole 702 is threadedly connected to a bolt 704, and the outer wall of the bolt 704 is threadedly connected to the lifting load body 8. The outer walls of the crossbar 701 and the locking block 703 are slidably connected to the lifting load body 8.
[0023] Working principle:
[0024] When using lifting tools for coupling machine tools:
[0025] The operator first adjusts the position of the mounting block 705 according to the length of the workpiece. The operator pulls the mounting block 705 outward. The movement of the mounting block 705 causes the crossbar 701 and the locking block 703 to slide along the inner wall of the lifting load body 8. When the mounting block 705 moves to the position, the operator controls the anti-detachment lever brake wrench 5 to make the anti-detachment lever 4 fit with the workpiece. The operator then rotates the bolt 704 to screw the bolt 704 into the lifting load body 8, and then into the threaded hole 702 on the crossbar 701, thereby fixing the position of the mounting block 705. This allows for the transportation of workpieces with different through-hole lengths, thus reducing work limitations.
[0026] After adjusting the position of the mounting block 705, the operator passes the lifting load 8 through the through hole of the workpiece, so that the right side of the workpiece is pressed against the anti-slip elastic rubber 3. The anti-slip elastic rubber 3 has the protective function of preventing slippage and disengagement. Then, the operator turns the anti-disengagement lever brake wrench 5 to drive the anti-disengagement lever 4 to rotate. When the right side of the anti-disengagement lever 4 is in contact with the workpiece, the operator passes the unlocking rope through the manual unlocking rope fixing hole 6 of the brake device and ties it to the outside of the mounting block 705, thereby fixing the anti-disengagement lever brake wrench 5 and the anti-disengagement lever 4. Then, the operator puts the lifting ring 1 on the hook of the crane and controls the crane to transport the workpiece to the workbench of the coupling machine tool. Then, the operator unties the unlocking rope and removes the lifting load 8 from the through hole of the workpiece.
[0027] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
