Description

Technical Field

[0001] The utility model relates to a lifting hoist, in particular to a clamp for finishing the lifting hoist wallboard on a lathe. Background Art

[0002] The wall panel is an important accessory in the hoist. Generally, the hoist includes a matching left wall panel and a right wall panel. Through multiple support rods, there is a spacing between the left wall panel and the right wall panel to form a space for the installation of other accessories such as guide wheels, lifting sprockets, and lifting chains. According to the installation and design of specific accessories, multiple installation holes are set on the wall panel, among which the center position of the wall panel generally has a hole position for matching the rotating shaft on the lifting sprocket. Correspondingly, the wall panel is punched out of the corresponding shape and hole position through the plate on the punching machine. Because the hole position has certain requirements for accuracy due to subsequent installation, the hole position processed by punching alone cannot meet the requirements, so the hole position needs to be fine-processed by boring, grinding, etc. For the hole position in the center of the wall panel, a lathe can be used for fine processing, but the three-jaw chuck on the lathe spindle can only fix one wall panel at a time, which is relatively inefficient.

[0005] The mounting plate has a first hole at the center of the first end surface;

[0006] At least two sleeve rods, fixing the first end surface of the mounting plate;

[0007] At least two sets of clamping assemblies, the clamping assemblies include: an L-shaped clamping block and a first bolt; the first bolt passes through a first block in the clamping block along the radial direction of the mounting plate and is threadedly connected to a first end face of the mounting plate, so that a second block in the clamping block along the axial direction of the mounting plate can abut against the first end face; when the second block abuts against the first end face, the sleeve rod covers the spacing area between the first block and the first end face.

[0008] Furthermore, the sleeve rod and the mounting plate are detachable, and a first end surface of the mounting plate is provided with a plurality of groups of first threaded holes for threaded connection of the sleeve rod.

[0027] See also Figure 1 and Figure 2 A clamp for lathe finishing of a lifting hoist wall panel comprises a mounting plate 1, two sleeve rods 2 and at least two sets of clamping components 3.

[0028] The first end surface 1b of the mounting plate 1 has a first hole 1a at the center thereof. The function of the first hole 1a is to allow the tool to completely pass through the entire hole when the lathe tool subsequently fine-processes the hole in the center of the wall panel 4. In addition, it can also allow part of the cut waste wire to enter the first hole 1a, thereby preventing the waste wire from remaining in the finely processed hole.

[0029] Two sleeve rods 2 are fixedly connected to the first end surface 1b of the mounting plate 1. Before the hole position at the center of the wall panel 4 is finely machined by the lathe, the remaining holes have been finely machined, and two holes are selected from these finely machined holes. Accordingly, two sleeve rods 2 are set according to the two selected holes, and the wall panel 4 is inserted into the sleeve rods 2 for positioning, so that the hole position at the center of the wall panel 4 corresponds to the first hole 1a of the mounting plate 1.

[0030] See also Figure 5 In some embodiments, the sleeve rod 2 and the mounting plate 1 are detachable. More specifically, one end surface of the sleeve rod 2 may be provided with a stud, which is threadedly connected to the first threaded hole 1c, so that the sleeve rod 2 can be detachably fixed to the mounting plate 1. The first end surface 1b of the mounting plate 1 is provided with a plurality of groups of first threaded holes 1c for the sleeve rod 2 to be threadedly connected, that is, the number of a group of first threaded holes 1c is two, which just fits two sleeve rods 2.

[0031] In this way, one clamp can be used with a variety of different wall panels 4, the outer edge sizes of these wall panels 4 are within a certain range, and the hole positions are designed differently. According to these wall panels 4, multiple groups of first threaded holes 1c are designed, and the installation position of the sleeve rod 2 on the installation plate 1 is adjusted to adapt to different wall panels 4.

[0032] See also Figure 1 and Figure 2 A set of clamping components 3 includes an L-shaped clamping block 3a and a first bolt 3b. For the clamping block 3a, the first block 3a1 is along the radial direction of the mounting plate 1, and the second block 3a2 is along the axial direction of the mounting plate 1. The first bolt 3b passes through the first block 3a1 in the clamping block 3a and is threadedly connected to the first end face 1b of the mounting plate 1. The first bolt 3b enables the second block 3a2 to abut against the first end face 1b, that is, the length of the first bolt 3b needs to be set, and the first bolt 3b is tightened. The nut of the first bolt 3b first approaches the first block 3a1, and then abuts against the first block 3a1, thereby pushing the clamping block 3a close to the first end face 1b, and finally the second block 3a2 abuts against the first end face 1b.

[0033] When the second block 3a2 abuts against the first end face 1b, the sleeve rod 2 covers the spacing area between the first block 3a1 and the first end face 1b, that is, at this time, the end of the sleeve rod 2 away from the first end face 1b exceeds the outer wall of the first block 3a1 close to the first end face 1b. In addition, the spacing of the spacing area is set according to the thickness of the wall panels 4, that is, the spacing area is equal to the total thickness of the wall panels 4 on the sleeve rod 2.

[0034] See also Figure 5 Further, based on the above-mentioned "the sleeve rod 2 and the mounting plate 1 are detachable", the first end face 1b of the mounting plate 1 is provided with a plurality of groups of second threaded holes 1d for threaded connection of the first bolts 3b, that is, the number of a group of second threaded holes 1d is the same as the number of the clamping assemblies 3.

[0035] In this way, one clamp can be used with a variety of different wall panels 4. When the outer edge size of the wall panel 4 varies greatly, the installation position of the clamping assembly 3 on the installation plate 1 can be adjusted to adapt.

[0036] Furthermore, the first threaded hole 1c and the second threaded hole 1d can be used interchangeably, that is, the first bolt 3b of the clamping assembly 3 can be threadedly connected to the first threaded hole 1c, and the stud on the sleeve rod 2 can also be connected to the second threaded hole 1d. It is more convenient to adjust the installation position of the clamping assembly 3 and the sleeve rod 2 on the installation plate 1.

[0037] See also Figure 2When the clamp is used, the mounting plate 1 is fixedly connected to the three-claw chuck of the lathe. First, loosen the first bolt 3b of the clamping assembly 3, then put the corresponding number of wall panels 4 on the two sleeve rods 2 in sequence, and then rotate the clamp block 3a to make the end of the first block 3a1 away from the second block 3a2 overlap with the wall panel 4, and finally tighten the first bolt 3b, and the clamp block 3a is matched with the mounting plate 1 to clamp and fix these wall panels 4 on the sleeve rods 2 together.

[0038] See also Figure 3 and Figure 4 In some embodiments, a deformable soft layer 3a3 is fixedly disposed on the side surface of the second block 3a2 close to the first end surface 1b. For example, a rubber layer may be bonded and fixedly disposed on the side surface of the second block 3a2.

[0039] In this way, the spacing area can be made slightly larger than the total thickness of the wall panels 4 on the sleeve rod 2, and the deformation of the soft layer 3a3 can be used to allow the clamping block 3a to still fit into the mounting plate 1 to clamp and fix the wall panels 4 on the sleeve rod 2 together.

[0040] See also Figure 3 and Figure 4 In some embodiments, the position of the first block 3a1 for the first bolt 3b to pass through is a waist-shaped through groove 3a1a.

[0041] In this way, the clamping block 3a can be moved relative to the first bolt 3b to adjust the overlapping portion of the first block 3a1 and the wall panel 4.

[0042] The rotation of the main shaft of the lathe drives the wall panels 4 to rotate together, and the tool of the lathe extends into the hole at the center of the wall panel 4 to perform fine processing on multiple wall panels 4 at one time.

[0043] See also Figure 1 and Figure 2 In some embodiments, the number of the clamping assemblies 3 is two groups, which are arranged opposite to each other.

[0044] In this way, when "putting the corresponding number of wall panels 4 onto the two sleeve rods 2 in sequence" mentioned above, the three-jaw chuck can be rotated to adjust the position of the clamp so that the two sets of clamping components 3 are on the left and the right. Correspondingly, when the first bolt 3b is loosened, the clamping block 3a is in a state where the second block 3a2 is facing downward under the action of its own gravity. When the wall panels 4 are put onto the two sleeve rods 2, there will be no interference between the wall panels and the clamping block 3a, which is faster and more convenient.
