Description

Technical Field

[0001] The utility model relates to the technical field of assembling machines, in particular to an opening caliper of a clamping mechanism of an assembling machine. Background Art

[0002] At present, ton barrels have a cylinder and a head, which are generally assembled by manual pairing. During the manufacturing process, the head and cylinder of the tank container need to be assembled. Previously, clamps were generally used for assembly. Due to the uneven force of the clamps, the cylinder roundness is not enough, so the misalignment of the cylinder and the head cannot be effectively solved. The operator needs to adjust them one by one through the jack, which is inefficient and labor-intensive. There is an urgent need for a safe, fast, easy-to-operate and labor-saving head and cylinder assembly device. Utility Model Content

[0003] The utility model aims to provide an opening caliper of a clamping mechanism for an assembling machine, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an opening caliper of a clamping mechanism of an assembling machine, comprising a base, a caliper seat is fixed on the base, movable calipers are hinged at both ends of the caliper seat, the caliper seat and the two movable calipers form an annular structure and the interior of the structure is used for a cylinder to extend into, a driving assembly is provided on the base, and the driving assembly is used to pull or push away one end of the two movable calipers away from the caliper seat, a first clamping plate is evenly distributed on the inner side of the caliper seat, and an extension line of the first clamping plate passes through the center of the caliper seat, and a second clamping plate is evenly distributed on the inner side of the movable caliper, and an extension line of the second clamping plate passes through the center of the movable caliper.

[0005] The above technical solution provides a caliper seat and a movable caliper, and the cylinder can be extended into the ring structure formed by the caliper seat and the two movable calipers. The two movable calipers can be pulled by the driving assembly so that the movable calipers automatically clamp the cylinder. Since the caliper seat and the movable caliper are respectively provided with a first clamping plate and a second clamping plate, the first clamping plate is used to support the bottom of the cylinder, and the second clamping plate can be used to support the side of the cylinder. The first clamping plate and the second clamping plate are arranged along the normal direction of the cylinder to ensure that the cylinder has good roundness after installation.

[0006] The caliper seat includes two fixed ring pieces, which are connected together by multiple first support columns and multiple first tensioning seats are also connected between the two fixed ring pieces. A first slot for inserting a first clamping plate is opened on the inner side of the fixed ring piece, and the end of the first clamping plate is fixedly connected to the tensioning seat by bolts. A support wheel is provided on one side of the first clamping plate, and the support wheel is against the surface of the cylinder.

[0007] The caliper seat of the above technical solution is composed of two fixed ring pieces to facilitate the installation of the first clamping plate. In addition, a support wheel is provided on one side of the first clamping plate to provide rolling support for the cylinder and facilitate the displacement of the cylinder.

[0008] The movable caliper includes two movable ring pieces, which are connected together by multiple second support columns and multiple second tensioning seats are also connected between the two movable ring pieces. A second slot for inserting a second clamping plate is provided on the inner side of the movable ring piece, and the end of the second clamping plate is fixedly connected to the second tensioning seat by bolts. A first support shaft is provided at one end of the movable caliper, and shaft holes are provided at both ends of the caliper seat. The support shaft is connected to the shaft hole to form a hinge.

[0009] The movable caliper of the above technical solution is assembled from two movable ring pieces through a support column to ensure the installation effect of the second clamping plate. At the same time, one end of the two movable ring pieces is hinged to the caliper seat by setting a support shaft to ensure that the movable caliper can rotate around the caliper seat to clamp the cylinder.

[0010] The driving assembly includes a mounting plate, which is fixedly connected to the base. A dual-output reducer is provided on the mounting plate. The output ends of the dual-output reducer are symmetrically arranged and connected to the output ends. Nut blocks are symmetrically connected to the two screw rods. A connecting rod is hinged on the nut block, and one end of the connecting rod is hinged to the end of the movable caliper away from the caliper seat.

[0011] The dual-output reducer of the above technical solution is used to drive the screw on its two output ends to rotate. A nut block is provided on the screw and the nut block is slidably connected to the mounting plate. Since the nut block is hinged to one end of the movable caliper through a connecting rod, when the screw rotates, the nut block can move in a straight line, thereby pulling the close ends of the two movable calipers closer or farther away, thereby realizing the operation of automatically clamping or loosening the cylinder.

[0012] The other end of the movable caliper is provided with a second supporting shaft, and the other end of the connecting rod is hinged to the second supporting shaft.

[0013] In the above technical solution, one end of the movable caliper is hinged to one end of the connecting rod through the second support shaft, so that the movement trajectory of the connecting rod is a plane. When the screw rotates, the nut can only move along the axial direction of the screw due to the limitation of the movement trajectory of the connecting rod. Therefore, it can be approximately regarded as a sliding connection between the nut block and the mounting plate, thereby ensuring the clamping effect.

[0014] It also includes a frame, the base is a slewing bearing, the slewing bearing includes an outer ring and an inner ring rotatably connected to each other, the inner ring is fixedly connected to the frame, and the outer ring is used to install a caliper seat and a driving component.

[0015] The slewing bearing of the above technical solution comprises an inner ring and an outer ring, which are rotatably connected, so that the slewing bearing can rotate the caliper seat and the movable caliper, thereby driving the cylinder to rotate, making the docking work more convenient.

[0016] A pantograph is installed on the frame, and the cross-sections of the first clamp and the second clamp are both trumpet-shaped. Conductive blocks are connected to the inner sides of the first clamp and the second clamp, and the conductive blocks are abutted against the outer surface of the cylinder. A fixing plate is provided on the edge of the outer ring, and a conductive ring seat is installed on the outer ring through the fixing plate. An annular groove is provided on the outer wall of the conductive ring seat, and a busbar is provided in the annular groove, and one end of the pantograph is abutted against the busbar.

[0017] The first and second clamping plates of the above technical solution are provided with conductive blocks, which are in contact with the pantograph busbar. The current of the pantograph is transmitted to the conductive blocks through the busbar, the fixing plate, the outer ring and the clamping plate, and then reaches the cylinder, so that the cylinder can also obtain current during the rotation process, thereby ensuring the welding effect.

[0018] Technical effects and advantages of the utility model:

[0019] 1. In this solution, the cylinder is extended into a ring structure formed by a caliper seat and two movable calipers, and the two movable calipers can be pulled by a driving assembly so that the movable calipers automatically clamp the cylinder.

Since the caliper seat and the movable caliper are respectively provided with the first clamping plate and the second clamping plate, the first clamping plate is used to support the bottom of the cylinder, and the second clamping plate can be used to support the side of the cylinder. The first clamping plate and the second clamping plate are arranged along the normal direction of the cylinder to ensure that the cylinder has good roundness after installation.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] This embodiment provides Figure 1 and Figure 2 The shown type of assembly machine clamping mechanism opening caliper includes a frame 1 and a base 2, a caliper seat is fixed on the base 2, and movable calipers are hinged at both ends of the caliper seat, the caliper seat and the two movable calipers form an annular structure and the interior is used for a cylinder 16 to extend, a driving assembly is provided on the base 2, and the driving assembly is used to pull or push away the two movable calipers away from the end of the caliper seat, a first clamping plate is evenly distributed on the inner side of the caliper seat, and the extension line of the first clamping plate passes through the center of the caliper seat, and a second clamping plate is evenly distributed on the inner side of the movable caliper, and the extension line of the second clamping plate passes through the center of the movable caliper. The base 2 of this embodiment is a slewing bearing, which includes an outer ring and an inner ring rotatably connected to each other, the inner ring is fixedly connected to the frame 1, and the outer ring is used to install the caliper seat and the driving assembly, the slewing bearing includes an inner ring and an outer ring, and the inner ring and the outer ring are rotatably connected, so that the slewing bearing can make the caliper seat and the movable caliper rotate, thereby driving the cylinder 16 to rotate, making the docking work more convenient.

[0030] Furthermore, when working, the open caliper can extend the cylinder 16 into the annular structure formed by the caliper seat and the two movable calipers. The two movable calipers can be pulled by the driving assembly so that the movable calipers automatically clamp the cylinder 16. Since the caliper seat and the movable caliper are respectively provided with a first clamping plate and a second clamping plate, the first clamping plate is used to support the bottom of the cylinder 16, and the second clamping plate can be used to support the side of the cylinder 16. The first clamping plate and the second clamping plate are arranged along the normal direction of the cylinder 16 to ensure that the installation of the cylinder 16 has good centering.

[0031] Furthermore, if Figure 1As shown, a pantograph 12 is installed on the frame 1, and the cross-sections of the first clamping plate and the second clamping plate are both trumpet-shaped. The inner sides of the first clamping plate and the second clamping plate are connected with conductive blocks, and the conductive blocks are abutted against the outer surface of the cylinder 16. A fixing plate is provided at the edge of the outer ring, and a conductive ring seat 13 is installed on the outer ring through the fixing plate. An annular groove is opened on the outer wall of the conductive ring seat 13, and a busbar 14 is provided in the annular groove. One end of the pantograph 12 is abutted against the busbar 14.

[0032] Since welding technology is generally used for docking, the cylinder 16 needs to be energized during the welding process. In this embodiment, conductive blocks are provided on the first clamping plate and the second clamping plate, and the pantograph 12 and the busbar 14 are in contact. The current of the pantograph 12 is transmitted to the conductive block through the busbar 14, the fixing plate, the outer ring and the clamping plate, and then reaches the cylinder 16, so that the cylinder 16 can also obtain current during the rotation process, thereby ensuring the welding effect.

[0033] like Figure 1 and Figure 4 As shown, the caliper seat includes two fixed ring pieces 3, the two fixed ring pieces 3 are connected together by multiple first support columns 17, and multiple first tensioning seats are also connected between the two fixed ring pieces 3. A first slot for inserting a first clamping plate is opened on the inner side of the fixed ring piece 3. The end of the first clamping plate is fixedly connected to the tensioning seat by bolts, and one side of the first clamping plate is provided with a support wheel that abuts against the surface of the cylinder 16.

[0034] Furthermore, the caliper seat is composed of two fixed ring pieces 3 for installation of the first clamping plate. In addition, a support wheel is provided on one side of the first clamping plate to provide rolling support for the cylinder 16 to facilitate displacement of the cylinder 16.

[0035] For example Figure 4 As shown, the movable caliper includes two movable ring pieces 4, the two movable ring pieces 4 are connected together by a plurality of second support columns 18, and a plurality of second tensioning seats are also connected between the two movable ring pieces 4, a second slot for inserting a second clamping plate is provided on the inner side of the movable ring piece 4, the end of the second clamping plate is fixedly connected to the second tensioning seat by bolts, a first support shaft 11 is provided at one end of the movable caliper, axial holes are provided at both ends of the caliper seat, the support shaft and the axial hole are connected to form a hinge, the movable caliper is assembled by two movable ring pieces 4 through support columns, so as to ensure the installation effect of the second clamping plate, and at the same time, one end of the two movable ring pieces 4 is hinged to the caliper seat by setting a support shaft, so as to ensure that the movable caliper can rotate around the caliper seat to clamp the cylinder 16.

[0036] like Figure 3As shown, the driving assembly includes a mounting plate, which is fixedly connected to the base 2, and a dual-output reducer 7 is provided on the mounting plate. The output ends of the dual-output reducer 7 are symmetrically arranged and connected to screw rods 8. Nut blocks 9 are symmetrically connected to the two screw rods 8. A connecting rod 10 is hinged on the nut block 9. One end of the connecting rod 10 is hinged to the end of the movable caliper away from the caliper seat. The dual-output reducer 7 is used to drive the screw rods 8 on its two output ends to rotate. Nut blocks 9 are provided on the screw rods 8 and the nut blocks 9 are slidably connected to the mounting plate. Since the nut block 9 is hinged to one end of the movable caliper through the connecting rod 10, when the screw rod 8 rotates, the nut block 9 can move in a straight line, thereby pulling the close ends of the two movable calipers closer or pushing them away, thereby realizing the operation of automatically clamping or loosening the cylinder 16.

[0037] Specifically, one end of the movable caliper is hinged to one end of the connecting rod 10 through the second support shaft 15, so that the movement trajectory of the connecting rod 10 is a plane. When the screw rod 8 rotates, the nut can only move along the axial direction of the screw rod 8 due to the restriction of the movement trajectory of the connection. Therefore, it can be approximately regarded as that the nut block 9 and the mounting plate are in a sliding connection, thereby ensuring the clamping effect.

[0038] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
