Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a dual-station exchange platform structure. Background Technology

[0002] During machining, it is necessary to swap the positions of two parts in different locations to continue subsequent processing. For example, initially, part A is machined on the left side and part B is machined on the right side. After completing this machining operation, part A needs to be moved to the right side and part B needs to be moved to the left side to continue subsequent machining. This swaps the positions of part A and part B, enabling multiple parts to be machined on the same machine, thus improving machining efficiency.

[0003] Currently, most machining equipment uses single-stage worktables, though double-stage worktables are also used. However, current double-stage worktables are simply two worktables stacked on top of each other, either parallel to each other on a horizontal plane or stacked vertically. For two worktables on the same plane, only one can be machined at a time. For stacked worktables, a drive mechanism is needed to adjust their vertical positions. Both of these methods change the machining position in one direction, but they cannot achieve staggered interchangeability of the two worktables while keeping the horizontal position constant.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0029] Reference Figure 1-5 As shown, the dual-station exchange platform structure of this utility model includes: a supporting base plate 1, on which an exchange drive assembly 2 is provided; two upright plates 3, which are fixedly installed on the supporting base plate 1, and the two upright plates 3 are arranged symmetrically and parallelly, with a transmission assembly 4 on the opposite surface of the upright plates 3, and the transmission assembly 4 is connected to the exchange drive assembly 2; a first worktable 5, which is connected to the transmission assembly 4, and the first worktable 5 is provided with a first cam 51, and the opposite surface of the upright plates 3 is provided with a first cam groove 31, the first cam 51 is disposed in the first cam groove 31, and the first cam 51 and the first cam groove 31 are tumbling connected; a second worktable 6, which is connected to the transmission assembly 4, and the second worktable 6 is provided with a second cam 61, the supporting base plate 1 is provided with a track plate 7, the track plate 7 is provided with a second cam groove 71, the second cam 61 is disposed in the second cam groove 71, and the second cam 61 and the second cam groove 71 are tumbling connected. The number of track plates 7 is two, and the two track plates 7 and the two upright plates 3 are arranged in a one-to-one correspondence. The track plates 7 and the upright plates 3 are both arranged perpendicular to the supporting base plate 1. The cross-sectional area of ​​the second worktable 6 is smaller than that of the first worktable 5, and the second worktable 6 is located within the cross-sectional area of ​​the first worktable 5.

[0030] Reference Figure 3As shown, the switching drive assembly 2 includes a servo drive motor 21, a reducer 22, and a transmission shaft 23. The servo drive motor 21 and the reducer 22 are connected, and the reducer 22 and the transmission shaft 23 are connected. Both ends of the transmission shaft 23 are connected to the transmission assembly 4. The support base plate 1 is a rectangular flat plate. The servo drive motor 21 and the reducer 22 are both fixedly mounted on the support base plate 1. The support base plate 1 is provided with several rotating shaft support seats. The transmission shaft 23 is set on the rotating shaft support seats to support the transmission shaft 23, and the rotating shaft support seats can ensure the rotation of the transmission shaft 23.

[0031] Reference Figure 3 As shown, the transmission assembly 4 includes a driving wheel 41, a gear belt 42, and several driven wheels 43. The driving wheel 41 is connected to the end of the transmission shaft 23, and the gear belt 42 is sleeved on the driving wheel 41 and the several driven wheels 43. The upright plate 3 is vertically mounted on the supporting base plate 1, and the driving wheel 41 and the several driven wheels 43 are mounted on opposite surfaces of the upright plate 3. Gear belt clamps 421 are connected to both the first worktable 5 and the second worktable 6, and the first worktable 5 and the second worktable 6 are connected by the gear belt clamps 421 and the gear belt 42.

[0032] Reference Figure 4 , 5 As shown, the cross-section of the first cam groove 31 is a trapezoid with an open bottom, and the cross-section of the second cam groove 71 is an inverted trapezoid with an open top. The trajectories of the first cam groove 31 and the second cam groove 71 are arranged in opposite directions. Thus, when the exchange drive assembly 2 drives the first worktable 5 and the second worktable 6 to move synchronously via the transmission assembly 4, due to the opposite arrangement of the first cam groove 31 and the second cam groove 71, when the first worktable 5 and the second worktable 6 move to the middle position of the first cam groove 31 and the second cam groove 71 respectively, the first worktable 5 and the second worktable 6 are stacked vertically. That is, the first worktable 5 is in a higher position under the guidance of the first cam groove 31, and the second worktable 6 is in a lower position under the guidance of the second cam groove 71. In this way, the first worktable 5 and the second worktable 6 pass alternately up and down. As the exchange drive assembly 2 drives the first worktable 5 and the second worktable 6 to move synchronously via the transmission assembly 4, the exchange of the first worktable 5 and the second worktable 6 is achieved.

[0033] Reference Figure 7 , 8As shown, the upright plate 3 is provided with a linear guide rail 32, and a slider 321 is provided on the linear guide rail 32. A slider 322 is fixedly connected to the slider 321. A linear guide rail 323 is installed on the first worktable 5. The linear guide rail 323 and the slider 322 are slidably connected. The linear guide rail 32 and the linear guide rail 323 are vertically arranged. The linear guide rail 32 is fixed. Through the connection of the slider 321 and the slider 322, the linear guide rail 323 can move horizontally along the linear guide rail 32. At the same time, the linear guide rail 323 can move vertically by its own movement. Through the coordination of horizontal and vertical movement, the first worktable 5 moves along the first cam groove 31 of the curved trajectory under the guidance of the first cam 51, thereby realizing the horizontal movement and vertical change of the first worktable 5. Because the linear guide rail 323 is fixed on the first worktable 5, the first worktable 5 moves along with it.

[0034] The track plate 7 is equipped with a linear guide rail 3 72, a slider 3 721 is connected to the linear guide rail 3 72, and a slider 4 722 is fixedly connected to the slider 3 721. The second worktable 6 is connected to a linear guide rail 4 723, and the linear guide rail 4 723 and the slider 4 722 are slidably connected. The linear guide rail 4 723 and the linear guide rail 3 72 are set vertically. The slider 3 721 can move linearly along the linear guide rail 3 72, realizing the horizontal movement of the second worktable 6. The vertical movement of the second worktable 6 is realized by the movement of the linear guide rail 4 723 relative to the slider 4 722. Thus, the second worktable 6 can move in a curved direction along the second cam groove 71 under the guidance of the second cam 61, thereby realizing the horizontal movement and vertical transformation of the second worktable 6.

[0035] Reference Figure 9 As shown, a worktable positioning assembly 8 is provided on one side of the support base plate 1. The worktable positioning assembly 8 includes a cylinder 81 and a pneumatic positioning pin 82. The cylinder 81 is mounted on the support base plate 1. The pneumatic positioning pin 82 is connected to the output end of the cylinder 81. The first worktable 5 and the second worktable 6 are provided with positioning holes. The cylinder 81 drives the pneumatic positioning pin 82 to insert into the positioning hole to achieve the positioning of the first worktable 5 and the second worktable 6.
