[0001] This utility model belongs to the technical field of emulsion filling equipment, specifically relating to a fixed clamping unit and a fixed clamping device including the fixed clamping unit. Background Technology

[0002] During the emulsion filling process, the bottles need to be clamped and secured. Existing clamping devices consist of three or four movable clamping blocks arranged at equal intervals along the circumference of the base. These movable clamping blocks can typically only move synchronously inward or outward, providing good clamping effect for cylindrical objects and ensuring that the center of the clamped cylindrical object is aligned with the center of the clamping device.

[0003] However, due to the diverse shapes of bottles containing various emulsions, such as elliptical cylinders and triangular prisms, existing clamping devices not only fail to provide effective clamping but also cause a significant misalignment between the center of the clamped bottle and the center of the clamping device, making subsequent processes impossible. Therefore, developing a clamping device suitable for clamping and fixing objects of various shapes has become an urgent technical challenge for those skilled in the art. Utility Model Content

[0027] refer to Figures 1 to 5 The fixed clamping unit 11 includes a base 111, a lifting support plate 112, four movable clamping blocks 113, and a stud assembly 114.

[0028] refer to Figures 2 to 4 The base 111 is used to install the lifting support plate 112, four movable clamping blocks 113 and stud assembly 114. It is provided with a cylindrical central guide groove 111a, four radial guide grooves 111b arranged radially in a central shape and equally spaced, and four limiting grooves 111c that are alternately arranged with the four radial guide grooves 111b and connected to the central guide groove 111a.

[0029] The base 111 has a bottom operation hole (not shown in the figure) at the center of the bottom, which is connected to the central guide groove 111a, and four side operation holes 111d on the side, which are respectively connected to the four radial guide grooves 111b.

[0030] In this embodiment, the base 111 is composed of a lower shell 111e and an upper shell 111f that are interlocked together, so as to facilitate processing, manufacturing and disassembly.

[0031] refer to Figure 2 and Figure 5 The lifting support plate 112 is located above the base 111 and is used to support the object to be clamped. The bottom of the lifting support plate 112 has a cylindrical central lifting column 112a and four limiting plates 112b. The central lifting column 112a has an axial threaded hole 112c that matches the support plate stud 114a. The lifting support plate 112 is mounted on the base 111 by means of the central lifting column 112a being movably mounted in the central guide groove 111a and the four limiting plates 112b being movably mounted in the four limiting grooves 111c. In this embodiment, the cross-sectional shapes of the limiting plates 112b and the limiting grooves 111c are mutually matching "V" shapes.

[0032] The periphery of the lifting support plate 112 has four radial notches 112d that respectively match the four radial guide grooves 111b and are alternately arranged with the four limiting plates 112b.

[0033] refer to Figures 2 to 4 The lower ends of the four movable clamping blocks 113 are respectively movably installed in the four radial guide grooves 111b, and the lower end of each movable clamping block 113 has a threaded hole 113a that matches the clamping block stud 114b. A vertically extending clamping groove 113b with a "V" shaped cross-section is provided at the center of the inner side of the movable clamping block 113.

[0034] In this embodiment, the movable clamping block 113 has a column 113c that matches the radial guide groove 111b and a clamping plate 113d fixedly disposed at the upper end of the column 113c.

[0035] In this embodiment, the base 111, the lifting support plate 112, and the movable clamping block 113 are all made of rigid plastic.

[0036] refer to Figure 3 The stud assembly 114 includes a single support plate stud 114a and four clamping block studs 114b, which are independent of each other.

[0037] The support plate stud 114a is located within the central guide groove 111a and is movably installed within the threaded hole 112c of the central lifting column 112a at the bottom of the lifting plate 112. The lower end face of the support plate stud 114a has a countersunk hole (not shown in the figure) with a cross-section of a regular polygon. In this embodiment, the countersunk hole of the support plate stud 114a has a regular hexagonal structure.

[0038] Four clamping block studs 114b are located within four radial guide grooves 114b and are movably installed within threaded holes 113a at the lower ends of four movable clamping blocks 113. The outer end face of each clamping block stud 114b is provided with a countersunk hole 114c with a regular polygonal cross-section. In this embodiment, the countersunk hole 114c of the clamping block stud 114b is a regular hexagonal structure.

[0039] refer to Figure 1 The drive unit 12 includes a support plate stud drive rod 121, four clamping block stud drive rods 122, a lifting drive component 123, four horizontal movement drive components 124, and a rotation drive component 125.

[0040] The support plate stud drive rod 121 is used to engage with the lower end of the support plate stud 114a to drive the support plate stud 114a to rotate, thereby causing the lifting support plate 112 to rise or fall. The upper end of the support plate stud drive rod 121 has a cross-sectional shape that matches the countersunk hole on the lower end face of the support plate stud 114a, facilitating its engagement or disengagement with the support plate stud 114a.

[0041] Four clamping block stud drive rods 122 correspond to four clamping block studs 114b, respectively, and are used to engage with the outer end of the corresponding clamping block stud 114b to drive the clamping block stud 114b to rotate, thereby causing the corresponding moving clamping block 113 to move horizontally inward or outward. The cross-sectional shape of the inner end of each clamping block stud drive rod 122 is a regular polygon that matches the hole of the clamping block stud 114b, facilitating its engagement or disengagement with the corresponding clamping block stud 114b.

[0042] The lifting drive component 123 is movably connected to the support plate stud drive rod 121 and is used to drive the support plate stud drive rod 121 to move up and down, so that the support plate stud drive rod 121 engages or disengages from the support plate stud 114a. In this embodiment, the lifting drive component 123 is a cylinder.

[0043] Four horizontal movement drive components 124 are movably connected to four clamping block stud drive rods 122, respectively, and are used to drive the corresponding clamping block stud drive rods 122 to move horizontally inward and outward, so that the clamping block stud drive rod 122 engages or disengages from the corresponding clamping block stud 114b. In this embodiment, the horizontal movement drive components 124 are also cylinders.

[0044] Since the movable connection methods between the lifting drive component 123 and the support plate stud drive rod 121, and between the horizontal movement drive component 124 and the four clamping block stud drive rods 122 are all existing technologies, they will not be described in detail here.

[0045] The rotary drive unit 125 is used to drive the support plate stud drive rod 121 and the four clamping block stud drive rods 122 to rotate, and includes a servo motor 125a and a six-way reducer 125b.

[0046] The output shaft of the servo motor 125a is connected to the input end of the six-way reducer 125b.

[0047] One output end of the six-way reducer 125b is coaxially connected to the support plate stud drive rod 121, and the other four output ends are respectively connected to the four clamping block stud drive rods 122 via transmission belts.

[0048] In this embodiment, the working principle of the fixing clamping device 10 is as follows:

[0049] The object to be clamped is placed on the supporting lifting plate 112. The lifting drive component 123 drives the supporting plate stud drive rod 121 to rise, so that the upper end of the supporting plate stud drive rod 121 passes through the bottom operating hole of the base 111 and is inserted into the countersunk hole at the lower end of the supporting plate stud 114a. Thus, the supporting plate stud drive rod 121 engages with the supporting plate stud 114a and drives the supporting plate stud 114a to rotate, thereby raising the supporting lifting plate 112 and the object to be clamped on it to a preset height. Then, the lifting drive component 123 drives the supporting plate stud drive rod 121 to descend, so that the supporting plate stud drive rod 121 separates from the supporting plate stud 114a.

[0050] Simultaneously, each horizontal movement drive 124 drives its corresponding clamping block stud drive rod 122 to move inward, causing the inner end of the clamping block stud drive rod 122 to pass through the side operating hole 111d of the base 111 and insert into the countersunk hole 114c at the outer end of the corresponding clamping block stud 114b. This engages the clamping block stud drive rod 122 with the clamping block stud 114b and drives the clamping block stud 114b to rotate, thereby causing the corresponding clamping block 113 to move inward to its preset position, thus clamping and fixing the object to be clamped and ensuring that the center of the object to be clamped is aligned with the center of the fixed clamping unit 11. Then, the horizontal movement drive 124 drives the corresponding clamping block stud drive rod 122 to move outward, causing the clamping block stud drive rod 122 to separate from the corresponding clamping block stud 114b.

[0051] After the fixed clamping is completed, the working principle of resetting the lifting support plate 112 and the clamping block 113 is similar to the above process, except that the rotation direction of the support plate stud drive rod 121 and the clamping block stud drive rod 122 is opposite, which will not be described again.
