Description

Technical Field

[0001] The utility model relates to the field of jig equipment, in particular to a vacuum adsorption jig. Background Art

[0002] A fixture is a large category of tools for carpentry, ironwork, fitter, machinery, electronic control and some other handicrafts. It is mainly used as a tool to assist in controlling position or movement. The fixture can be divided into three categories: process assembly fixtures, project test fixtures and circuit board test fixtures.

[0003] In the production process of mobile phone cases, metal plates need to be processed, and during the processing, jigs are needed to fix the metal plates. Existing jigs usually use air pumps to vacuum and adsorb them during use, making the adsorption more stable.

[0004] However, the existing vacuum adsorption fixture requires manual correction of the position of the metal plate during operation. When the air pump is turned on, the metal plate has been adsorbed under the action of vacuum, and manual adjustment is inconvenient. In addition, there may be differences in the alignment position, which may affect subsequent processing. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a vacuum adsorption fixture to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vacuum adsorption fixture, comprising a workbench, fixed plates movably installed on both sides of the workbench, and a movable plate movably installed on one side of the fixed plate, a connecting plate movably installed on one end of the movable plate, fixed rods movably installed on both sides of the workbench, and a connecting rod is fixedly installed on one end of the fixed rod, and a round block is fixedly installed on the other end of the fixed rod, a screw rod movably installed inside the workbench, and a movable block movably installed on one end of the screw rod, a protrusion is fixedly installed on one end of the movable block, limit blocks are fixedly installed on both ends of the movable plate, and a steel cable is installed on one side of the limit block, and the two groups of limit blocks are connected by the steel cable, and the limit block and the fixed plate are slidably connected.

[0007] By adopting the above technical solution and setting a movable plate and a movable block, when the screw rod rotates, the movement of the movable block can cause the extrusion block to squeeze the connecting rod, thereby causing the connecting rod to move downward, and then driving the round block to pull the steel cable, causing the movable plate to move, thereby realizing the correction and alignment of the movable plate and the rubber block to the metal plate, without the need for manual correction, making the position more accurate.

[0008] The utility model is further configured that pulleys are arranged on both sides of the round block, and an empty groove cooperating with the steel cable is opened on the outer side of the pulley, a spring is installed on one side of the limit block, an extrusion block is fixedly installed on one side of the movable block, and the extrusion block cooperates with the connecting rod.

[0009] By adopting the above technical solution and setting a pulley, the movement of the steel cable is made more labor-saving, does not consume too much force, reduces work intensity, and makes the extrusion block smoother in the process of extruding the connecting rod, while reducing the work intensity of the staff.

[0010] The utility model is further configured that a turntable is fixedly installed at one end of the screw rod, a threaded groove matched with the screw rod is opened in the middle of the movable block, and limiting columns are fixedly installed on both sides of the movable block.

[0011] By adopting the above technical solution and setting a threaded groove in the middle of the movable block, the movement of the movable block can be controlled by the screw rod to ensure the overall working stability. At the same time, the limit columns on both sides of the movable block can ensure that the movable block will not deviate during the movement.

[0012] The utility model is further configured that an air pump is installed inside the workbench, and ventilation holes are opened at one end of the workbench, and the number of ventilation holes is multiple groups, and an empty slot for the fixed plate and the movable plate to move is opened at one end of the workbench.

[0013] By adopting the above technical solution and providing an empty slot at the end of the workbench, the fixed plate and the movable plate have enough movable space, ensuring that the fixed plate and the movable plate can be retracted when not in use without affecting the external space.

[0014] The utility model is further configured that a rubber block is fixedly installed on one side of the movable plate, and the number of the rubber blocks is multiple groups, and the movable plate and the connecting plate are slidably connected.

[0015] By adopting the above technical solution and arranging the rubber blocks, the metal plates can have more adaptability during the pushing process, thus avoiding large displacement or damage caused by forced pushing, and at the same time separating the metal plates.

[0016] In summary, the utility model mainly has the following beneficial effects:

[0017] The utility model provides a movable plate and a movable block. When the screw rod rotates, the movement of the movable block can make the extrusion block squeeze the connecting rod, so that the connecting rod moves down, and then drives the round block to pull the steel cable, so that the movable plate is displaced, so that the movable plate and the rubber block can be corrected and aligned with the metal plate without manual correction, so that the position is more accurate. At the same time, when the movable rod moves, the convex block can first contact the connecting plate, so that the movable plate and the fixed plate move up, and then subsequent correction operations can be achieved. By providing a displaceable connecting plate, the movable plate can be raised when work is needed, and the movable plate and the fixed plate can be retracted when work is not needed, which will not affect the space on the surface of the workbench and will not affect daily work.

DETAILED DESCRIPTION

[0025] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] A vacuum adsorption fixture, such as Figure 1-6As shown, it includes a workbench 1, fixed plates 2 are movably installed on both sides of the workbench 1, and a movable plate 3 is movably installed on one side of the fixed plate 2, and a connecting plate 17 is movably installed on one end of the movable plate 3, fixed rods 11 are movably installed on both sides of the workbench 1, and a connecting rod 10 is fixedly installed on one end of the fixed rod 11, and a round block 12 is fixedly installed on the other end of the fixed rod 11, a screw rod 6 is movably installed inside the workbench 1, and a movable block 7 is movably installed on one end of the screw rod 6, and a convex block 8 is fixedly installed on one end of the movable block 7, and a limit block 15 is fixedly installed on both ends of the movable plate 3, and a steel cable 14 is installed on one side of the limit block 15. , and the two groups of limit blocks 15 are connected by a steel cable 14, and the limit block 15 is slidably connected to the fixed plate 2. When the screw rod 6 continues to rotate, the extrusion block 9 begins to contact the connecting rod 10. When the connecting rod 10 is squeezed and moved downward, the fixed rod 11 is driven downward. When the fixed rod 11 moves downward, the round block 12 is driven to move, so that the steel cable 14 is pulled. When the steel cable 14 is pulled, the limit block 15 moves. When the limit block 15 moves, the movable plate 3 is driven to move, so that the movable plate 3 is moved closer to the middle, thereby realizing the correction of the metal plate.

[0028] See also Figure 3-5 Pulleys 13 are provided on both sides of the round block 12, and an empty groove cooperating with the steel cable 14 is opened on the outer side of the pulley 13. A spring 16 is installed on one side of the limit block 15, and an extrusion block 9 is fixedly installed on one side of the movable block 7, and the extrusion block 9 cooperates with the connecting rod 10. By setting the pulley 13, the movement of the steel cable 14 is more labor-saving, does not consume too much force, reduces the work intensity, and makes the extrusion block 9 smoother in the process of extruding the connecting rod 10, while reducing the work intensity of the staff.

[0029] See also Figure 1-2 A turntable 5 is fixedly installed at one end of the screw rod 6, and a threaded groove matching the screw rod 6 is opened in the middle of the movable block 7. Limiting columns are fixedly installed on both sides of the movable block 7. By setting the threaded groove in the middle of the movable block 7, the movement of the movable block 7 can be controlled by the screw rod 6 to ensure the overall working stability. At the same time, the limiting columns on both sides of the movable block 7 can ensure that the movable block 7 will not deviate during the movement.

[0030] See also Figure 6 An air pump is installed inside the workbench 1, and a vent 18 is opened at one end of the workbench 1, and the number of the vents 18 is multiple. An empty slot for the fixed plate 2 and the movable plate 3 to move is opened at one end of the workbench 1. By setting the empty slot at the end of the workbench 1, the fixed plate 2 and the movable plate 3 have enough space for movement, ensuring that the fixed plate 2 and the movable plate 3 can be retracted when not in use without affecting the external space.

[0031] See also Figure 1-2A rubber block 4 is fixedly installed on one side of the movable plate 3, and the number of rubber blocks 4 is multiple groups. The movable plate 3 and the connecting plate 17 are slidably connected. The rubber blocks 4 are set so that the metal plate has more adaptability during the pushing process, avoiding large displacement or damage caused by forced pushing, and separating the metal plates at the same time.

[0032] The working principle of the utility model is as follows: during the working process, when the position of the metal plate needs to be corrected, the turntable 5 is rotated to make the screw rod 6 rotate. When the screw rod 6 rotates, the movable block 7 is displaced. When the movable block 7 is displaced, the protrusion 8 is driven to first contact the connecting plate 17, so that under the extrusion of the protrusion 8, the connecting plate 17 moves up. When the connecting plate 17 moves up, the movable plate 3 is driven to move up, so that the fixed plate 2 moves up. At this time, the movable plate 3 and the fixed plate 2 protrude from the surface of the workbench 1. When the screw rod 6 continues to rotate, the extrusion block 9 begins to contact the connecting rod 10. When the connecting rod 10 is squeezed and moves downward, the fixed rod 11 is driven to move downward. When the fixed rod 11 moves downward, the round block 12 is driven to move, so that the steel cable 14 is subjected to a pulling force. When the steel cable 14 is pulled, the limit block 15 is moved. When the limit block 15 moves, the movable plate 3 is driven to move, so that the movable plate 3 is close to the middle, thereby realizing the correction of the metal plate.
