Description

Technical Field

[0001] This utility model belongs to the technical field of carton production line equipment, specifically relating to a production line clamping device. Background Technology

[0002] A production line clamping device is a piece of equipment used in carton production projects to fix and hold cartons during their operation on the production line. It is typically installed at different workstations on automated carton production lines to stabilize the position of cartons during manufacturing, processing, and assembly, ensuring efficient production line operation and quality control.

[0003] However, when the clamping device is applied to the carton processing production line, after the carton is transported to the clamping station, the clamping device will clamp the carton from both sides, fixing the carton at the current station, which facilitates the processing of the carton by the components at the station. However, when the height or volume of the carton is large, the original clamping plate clamping the carton has a relatively small clamping area. Therefore, the clamping plate is prone to displacement of the carton due to its large volume or height, which can easily cause errors when processing the carton at that station. Utility Model Content

[0004] The purpose of this utility model is to provide a production line clamping device to solve the problem mentioned in the background art that when the height or volume of the carton is large, the original clamping plate clamps the carton, but the relative clamping area of ​​the clamping plate is small, so the clamping plate is prone to displacement of the carton due to the large volume or height of the carton.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a production line clamping device, comprising a gantry frame and a column B vertically fixed to the bottom right end of the gantry frame, a column A vertically arranged at the bottom left end of the gantry frame, and both column A and column B are fixedly connected to the gantry frame by welding, a clamping cylinder B horizontally fixed on the outer wall of the right end of the column B near its lower side, a plunger arranged inside the clamping cylinder B, a cylinder shaft B arranged at the left end of the plunger, and the left end of the cylinder shaft B passes through the column B and is exposed outside the outer wall of the left end of the column B, a clamping plate arranged at the left end of the cylinder shaft B, and an enlarging clamping device arranged on the outer wall of the left end of the clamping plate;

[0006] The enlarged clamping device includes a metal enlarged plate, side sleeves, top sleeves, stabilizing guide rods, and stabilizing guide holes. Side sleeves are provided on the outer walls of the front and rear ends of the lower side of the center of the metal enlarged plate. Two top sleeves are provided on the outer wall of the lower right end of the center of the metal enlarged plate, and both top sleeves are sleeved on the outside of the top of the clamping plate from top to bottom. The two side sleeves are respectively sleeved on the outside of the front and rear ends of the clamping plate. A stabilizing guide hole is provided in the transverse direction near the upper side of the column B, and a stabilizing guide rod is inserted into the inside of the stabilizing guide hole.

[0007] Preferably, the enlarged clamping device further includes a fixing screw and a fixing screw hole. The fixing screw hole is located inside the left end of the stabilizing guide rod, and the opening direction of the fixing screw hole is to the left. The fixing screw is horizontally fixed to the outer wall of the metal enlarged plate near the upper right end, and the fixing screw hole is threaded onto the outside of the fixing screw.

[0008] Preferably, the stabilizing guide rod can move left and right inside the stabilizing guide hole, the vertical length of the metal enlargement plate is three times or more the vertical length of the clamping plate, and the length of the stabilizing guide rod is greater than the stroke length of the clamping cylinder B pushing the cylinder shaft B.

[0009] Preferably, a clamping cylinder A is horizontally fixed on the outer wall of the lower left end of the column A. A plunger is provided inside the clamping cylinder A. A cylinder shaft A is provided at the right end of the plunger. The right end of the cylinder shaft A passes through the column A and is exposed outside the outer wall of the right end of the column A.

[0010] Preferably, a clamping plate is also provided at the right end of the cylinder shaft A, and an enlarged clamping device is also provided on the outside of the clamping plate at the right end of the cylinder shaft A.

[0011] Preferably, a control box is provided at the center of the top of the gantry frame, and multiple position probes are equidistantly arranged on the outer wall of the bottom end of the gantry frame, and the position probes are electrically connected to the control box.

[0012] Compared with the prior art, the present invention provides a production line clamping device, which has the following advantages:

[0013] This invention adds a novel enlarged clamping device to each of the two clamping plates of the production line clamping device. The enlarged clamping device increases the clamping contact area of ​​the two clamping plates on the carton on the production line. When the carton on the production line is large, the enlarged clamping device can increase the clamping area, thus making more full contact with the outer wall of the carton on the production line.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1-4The production line clamping device shown includes a gantry frame 11 and a column B8 vertically fixed to the bottom right end of the gantry frame 11. A column A3 is vertically arranged at the bottom left end of the gantry frame 11, and both column A3 and column B8 are fixedly connected to the gantry frame 11 by welding. A clamping cylinder B9 is horizontally fixed on the outer wall of the lower right end of column B8. A plunger is arranged inside the clamping cylinder B9, and a cylinder shaft B7 is arranged at the left end of the plunger. The left end of the cylinder shaft B7 passes through column B8 and is exposed outside the outer wall of the left end of column B8. A clamping plate 6 is arranged at the left end of the cylinder shaft B7. A clamping cylinder A1 is horizontally fixed on the outer wall of the lower left end of column A3. A plunger is installed inside the clamping cylinder A1, and a cylinder shaft A4 is installed at the right end of the plunger. The right end of the cylinder shaft A4 passes through column A3 and protrudes from the outer wall of the right end of column A3. A clamping plate 6 is also installed at the right end of the cylinder shaft A4, and an enlarging clamping device 5 is also installed outside the clamping plate 6 at the right end of the cylinder shaft A4. Mounting bases 2 are welded to the bottom of both column A3 and column B8. A control box 10 is installed at the center of the top of the gantry frame 11. Multiple... A position probe 12 is provided, and the position probe 12 is electrically connected to the control box 10. When using this production line clamping device, it is first necessary to determine the installation position of the production line clamping device on the carton production line. Then, the production line clamping device needs to be hoisted to the installation position on the production line. At this time, the mounting bases 2 at the bottom of the columns A3 and B8 are both attached to the installation position. Then, the two mounting bases 2 are firmly fixed to the production line with screws. Then, the pressure supply equipment needs to be connected to the clamping cylinders A1 and B9. Then it can be put into use. When the cartons on the production line are conveyed... After being delivered to the lower side of the gantry 11, the position probe 12 on the outer wall of the bottom end of the gantry 11 will detect the position of the carton. After the carton reaches the accurate position, the control box 10 will control the pressure supply device to supply pressure to the clamping cylinders A1 and B9, so that the cylinder shafts A4 and B7 push the clamping plate 6 to clamp the two outer walls of the carton, thereby clamping the carton on the production line. Then, other parts or equipment on the production line will process the carton. After the processing is completed, the clamping plate 6 releases the carton, and the carton will be transported to the next production station by the production line.

[0021] like Figure 1 , Figure 3 and Figure 4As shown, an enlarged clamping device 5 is provided on the outer wall of the left end of the clamping plate 6. The enlarged clamping device 5 includes a metal enlarged plate 13, side sleeves 14, top sleeves 15, a stabilizing guide rod 16, and a stabilizing guide hole 17. Side sleeves 14 are provided on the outer walls of the front and rear ends of the lower side of the center of the metal enlarged plate 13. Two top sleeves 15 are provided on the outer wall of the lower right end of the center of the metal enlarged plate 13. Both top sleeves 15 are sleeved on the top of the clamping plate 6 from top to bottom. The two side sleeves 14 are respectively sleeved on... The column B8 is connected to the front and rear ends of the clamping plate 6. A stabilizing guide hole 17 is provided in the upper horizontal direction near the outside of the column B8. A stabilizing guide rod 16 is inserted into the inside of the stabilizing guide hole 17. The enlarged clamping device 5 also includes a fixing screw 18 and a fixing screw hole 19. The fixing screw hole 19 is located inside the left end of the stabilizing guide rod 16, and the opening direction of the fixing screw hole 19 is to the left. The fixing screw 18 is horizontally fixed to the outer wall of the metal enlarged plate 13 near the upper right end, and the fixing screw hole 19 is threaded onto the outside of the fixing screw 18.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the stabilizing guide rod 16 can move left and right inside the stabilizing guide hole 17. The vertical length of the metal expansion plate 13 is three times or more than the vertical length of the clamping plate 6. The length of the stabilizing guide rod 16 is greater than the stroke length of the clamping cylinder B9 pushing the cylinder shaft B7. When the volume and height of the cartons on the production line are large, the clamping area of ​​the original clamping plate 6 is relatively small, so it is easy to have an unstable clamping. At this time, it is necessary to install the expansion clamping device 5 on the clamping plate 6 to increase the clamping area of ​​the cartons. Specifically, the metal expansion plate 13 needs to be close to the clamping plate 6, and both top sleeves 15 need to be located on the upper side of the clamping plate 6. Then, the metal expansion plate 13 is moved downward until both top sleeves 15 are sleeved on the outside of the top of the clamping plate 6, and the two side sleeves 14... The two side sleeves 14 are respectively fitted onto the front and rear ends of the clamping plate 6. The top sleeve 15 can fix the metal expansion plate 13, while the two side sleeves 14 can prevent the metal expansion plate 13 from shifting back and forth. Then, the stabilizing guide rod 16 needs to be inserted into the stabilizing guide hole 17, and the fixing screw hole 19 inside the stabilizing guide rod 16 is connected to the outside of the fixing screw 18 near the top of the metal expansion plate 13, and then tightened. When clamping the carton, the clamping plate 6 will drive the metal expansion plate 13 to clamp onto the outer wall of the carton. Because the metal expansion plate 13 has a large area, it can clamp the carton more firmly. During the clamping process, the stabilizing guide rod 16 will move synchronously in the stabilizing guide hole 17, which makes the expansion clamping device 5 more stable and efficient in use.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
