Description

Technical Field

[0001] The invention relates to the technical field of electric screwdrivers, in particular to an electric screwdriver balancing bracket with a positioning function. Background Art

[0002] The electric screwdriver bracket, also called the electric screwdriver vertical bracket, is composed of imported bearings and stainless steel guide shafts. It is a standard product used to correct the irregular movements of individual employees when using electric screwdrivers.

[0003] The existing bracket ensures that the electric screwdriver always maintains a 90° vertical locking angle during operation, which can maximize the locking accuracy of the screw. This not only reduces the problem of poor screw locking due to operator error, but also effectively prevents product quality risks and reduces the incidence of defective products; secondly, the vertical bracket takes into account the comfort and safety of the operator. It effectively alleviates the problem of insufficient strength that may occur when the operator holds the electric screwdriver for a long time, thereby avoiding possible quality problems and work-related accidents and protecting the health of employees.

[0004] Although the existing electric screwdriver bracket can greatly relieve the labor intensity of the staff at work, there are still defects in the positioning efficiency of the bracket. Although the existing bracket has a relatively high degree of freedom, it is difficult to keep the electric screwdriver and the workpiece surface vertical for some parts assembly. For example, for workpieces with inclined surfaces, the electric screwdriver needs to be tilted during the installation of screws, and some electric screwdriver brackets do not have or cannot effectively allow the electric screwdriver to be tilted. Therefore, in order to enable the electric screwdriver to be fully applied to various processing, the existing technology improves the problems caused by it. For example, the electric screwdriver can be rotated on the Z axis so that it can correspond to parts of various angles, but it is still necessary to manually find the fitting point between the electric screwdriver and the part surface to ensure that the electric screwdriver and the part surface are 90°, and then manually turn the tightening knob to lock the angle after the electric screwdriver is turned. The operation is very troublesome, and the manual prediction of the vertical angle between the electric screwdriver and the workpiece makes the electric screwdriver tilt angle have an error, and excessive positioning of negative angles may occur, so the positioning effect is not good. For this reason, we propose an electric screwdriver balancing bracket with a positioning function. Summary of the invention

DETAILED DESCRIPTION

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

[0028] See also Figure 1-8 The present invention provides a technical solution: an electric batch balance bracket with a positioning function, comprising a base 1, as shown in the attached Figure 1As shown, a workpiece placing table is fixedly installed on the top of the base 1, and a plurality of workpiece positioning holes are provided on the placing table for tightening during the workpiece processing process. The base 1 and the placing table are calibrated and placed and fixed by a level at a certain place in the room. First sliding bars 2 are fixedly installed on both sides of the top of the base 1, and a limited bridge 3 is slidably connected between the two first sliding bars 2. A Z-axis rod 4 is fixedly connected to the middle of one side of the base 1, and a clamping plate 16 is slidably connected to the Z-axis rod 4. A connecting pin 22 is fixedly installed on the top of the clamping plate 16, and a connecting rod 23 is rotatably connected to the connecting pin 22. A measuring plate 18 is fixedly connected to one end of the connecting rod 23, and a rotating gear disc 34 is fixedly connected to the other end of the connecting rod 23. One side of the rotating gear disc 34 is fixed A corresponding ring 35 is fixedly installed, one end of the connecting rod 23 is rotatably connected to a rotating rod 17, a damping ring 36 is fixedly installed on the side of the bottom of the rotating rod 17 facing the rotating gear disk 34, and the corresponding ring 35 and the damping ring 36 are engaged together, a pair of connecting seats 6 are detachably connected to the top of the rotating rod 17, one side of the top of each connecting seat 6 is fixedly connected to an X-axis rod 7, a first slide 10 is slidably connected to a pair of X-axis rods 7 located on one side of the same connecting seat 6, a top plate 8 is fixedly installed on the top of the first slide 10, a Y-axis rod 9 is fixedly connected to the bottom of the top plate 8, a second slide 11 is slidably connected to the Y-axis rod 9, and an electric screwdriver 12 is detachably connected to the second slide 11. When the electric screwdriver 12 is not in use, the device is in an attached state. Figure 1 In the state shown, when the electric screwdriver 12 needs to work, the workpiece is first placed on the placement table manually, and then the clamping plate 16 is pressed manually to make the weighing plate 18 contact the surface of the workpiece. If the bottom of the weighing plate 18 is just parallel to or fits the surface of the workpiece, there is no need to rotate the connecting seat 6. A pair of handles at the bottom of the second slide 11 are directly held manually (marked in the figure) to drive the second slide 11 to slide downward along the Y-axis 9, so that the threaded hole on the surface of the workpiece and the electric screwdriver 12 are 90 degrees. The electric screwdriver 12 directly tightens the screw on the workpiece. During the processing, the workpiece can be appropriately moved so that each screw can be installed in the other threaded holes on the workpiece.

[0029] When the surface of the workpiece is specially customized and in an inclined state, one end of the measuring piece 18 will first fit the workpiece surface, and the other end is suspended and away from the workpiece surface. At this time, manual intervention is required to press the other end of the measuring piece 18 downward so that both ends of the measuring piece 18 fit the workpiece surface, which will cause the measuring piece 18 to rotate in the process. During the rotation of the measuring piece 18, the connecting rod 23 is driven to rotate, and the rotation of the connecting rod 23 drives the rotating toothed disc 34 to rotate. The rotation of the rotating toothed disc 34 causes the corresponding ring 35 to drive the damping ring 36 to rotate. The rotation of the damping ring 36 can drive the rotating rod 17 to rotate in the driving direction, so that the two connecting seats 6 are separated. The measuring plate 18 is spaced apart from the connecting seat 6 at the other end thereof, thereby allowing the connecting seat 6 at the other end of the measuring plate 18 to slide in a circular arc along the limiting bridge 3. When the two ends of the measuring plate 18 are in contact with the surface of the workpiece, the angle of the rotating rod 17 is limited, so that the processing angle of the electric screwdriver 12 is perpendicular to the surface of the workpiece, and then perpendicular to the screw hole of the workpiece, thereby improving the accuracy of the workpiece processed by the electric screwdriver 12 and preventing misalignment between the electric screwdriver 12 and the screw. If the screw hole on the surface of the workpiece is not within the standard tolerance, the damping ring 36 can be used to finely adjust the angle of the rotating rod 17 by hand after the angle of the rotating rod 17 is limited, so that the electric screwdriver 12 and the processed workpiece maintain a certain error range, ensuring that the electric screwdriver 12 is within the standard tolerance when turning the screw.

[0030] Specifically, a limiting plate 25 is fixedly installed at one end of the clamping plate 16, and a second spring 26 is movably connected to one side of the limiting plate 25. The initial state of the second spring 26 is a semi-compressed state, and one end of the second spring 26 is fixedly connected to a fixed toothed disc 24, and the fixed toothed disc 24 and the rotating toothed disc 34 are meshed together. The other end of the clamping plate 16 has a sliding portion 1602 that approaches the outer ring of the Z-axis rod 4. When the rotating rod 17 rotates, the rotating toothed disc 34 is rotated, so that the rotating toothed disc 34 and one side of the fixed toothed disc 24 are in conflict with each other. In this process, the second spring 26 repeatedly generates compression and unloads energy. After the two ends of the measuring plate 18 are in contact with the surface of the workpiece, the fixed toothed disc 24 and the rotating toothed disc 34 remain stationary, so that the second spring 26 generates a repulsive force on the rotating toothed disc 34, so that the rotation angle of the rotating rod 17 is fixed, thereby improving the stability of the rotating rod 17 after rotation.

[0031] Specifically, placement areas 1701 are provided on both sides of the top of the rotating rod 17, and a counter-end 603 is fixedly installed at one end of the bottom of each connecting seat 6 to be accommodated in the placement area 1701. A pair of second sliding rods 30 are fixedly connected to both sides of the top of the rotating rod 17, and a pull plate 31 is slidably connected to each pair of the second sliding rods 30. A blocking column 32 is fixedly connected to one side of each of the pull plates 31. The blocking column 32 is movably connected to the rotating rod 17, and a third spring 33 is fixedly installed between each of the pull plates 31 and the rotating rod 17. The blocking column 32 and the counter-end 603 converge and intersect each other in the placement area 1701. When the two ends of the measuring plate 18 are in contact with the surface of the workpiece, the two connecting seats 6 are in the process of separation. During this process, the counter end 603 at the bottom of the active connecting seat 6 and the end of the blocking column 32 are separated, and the other connecting seat 6 does not move. After the counter end 603 on the active connecting seat 6 generates a repulsive force on the blocking column 32, the blocking column 32 moves away from the rotating rod 17, so that the pull plate 31 slides on a pair of second sliding rods 30, and the blocking column 32 contracts, so that the rotating rod 17 can drive the active connecting seat 6 to rotate, allowing the electric screwdriver 12 to follow the rotating rod 17 to tilt at a certain angle.

[0032] Furthermore, a fixing ring 27 is fixedly installed on the outer ring of the fixed toothed disc 24, and a pair of locking rings 2701 are fixedly connected to one side of the fixing ring 27, and each locking ring 2701 is provided with an inclined portion 2702. The other side of the limiting piece 25 is rotatably connected to a rotating piece 28, and both ends of the rotating piece 28 extend toward the axis of the fixing ring 27 to form a wedge-shaped portion 29, and the fixed toothed disc 24 squeezes the locking ring 2701 through the wedge-shaped portion 29 to fit on one side of the rotating toothed disc 34. In order to prevent manual support of the electric screwdriver during use, 12 When processing the workpiece, the angle of the rotating rod 17 changes, causing the screw installation to deviate from the screw hole. After the two ends of the measuring piece 18 are in contact with the surface of the workpiece, the rotating piece 28 should be rotated by hand immediately. During the rotation of the rotating piece 28, the wedge-shaped portion 29 is driven to tangent to the inclined portion 2702, and the locking ring 2701 is moved toward the side of the rotating toothed disc 34 after being squeezed, so that the rotating toothed disc 34 and the fixed toothed disc 24 are closely fitted together, preventing the locking effect of the fixed toothed disc 24 on the rotating toothed disc 34 from being reduced during the rotation of the rotating rod 17.

[0033] Furthermore, the first magnet 5 is fixedly installed on both sides of the Z-axis rod 4, and the second magnet 601 is fixedly installed on the opposite surfaces of the two connecting seats 6. The second magnet 601 and the first magnet 5 have opposite poles and are attracted together. A reinforcing rib 602 is fixedly installed on one side of each connecting seat 6. In order to keep the connecting seat 6 sliding on the Z-axis rod 4, the second magnet 601 and the first magnet 5 are attracted together to prevent the connecting seat 6 from swinging randomly, thereby obstructing the processing space of the electric screwdriver 12.

[0034] Furthermore, both ends of the measuring plate 18 are fixedly connected with extension plates 19, each of which extends toward the redundant space on the upper part of the base 1, and one end of the extension plate 19 is rotatably connected with a movable plate 20, and one end of each movable plate 20 is threadedly connected with a positioning nozzle 21, and a collision piece is fixedly installed at the bottom of the positioning nozzle 21; the limiting bridge 3 is semicircular in design, and the collision piece at the bottom of the positioning nozzle 21 is made of soft rubber. When the surface of the workpiece is irregular or the cross-section is discontinuous, the screw holes on the surface of the workpiece are in various tilted states. Therefore, the surface of the workpiece can be manually predicted, and then the movable plate 20 is pulled by hand to explore the surface of the workpiece, and the collision piece at the bottom of the positioning nozzle 21 contacts the workpiece. If a match occurs, the area where the two connecting seats 6 are in Figure 1 In this state, the electric screwdriver 12 can directly process the surface of the workpiece. If the collision plate does not match the surface of the workpiece, it is necessary to judge based on the distance between the two collision plates and the surface of the workpiece. Press the movable plate 20 by hand to change the angle of the rotating rod 17, and further locate the rotation angle of the rotating rod 17, thereby improving the universality of the device in processing various workpieces.

[0035] Furthermore, each of the second slides 11 is threadedly connected to a threaded locking head 13 on one side, and the outer ring of the electric screwdriver 12 is provided with two threaded holes. The threaded locking head 13 is matched and connected by passing through the second slide 11 and the threaded holes. When one end of the measuring piece 18 is in contact with the surface of the workpiece, the angle of the rotating rod 17 needs to be changed. Therefore, one of the threaded locking heads 13 connected to the electric screwdriver 12 can be manually separated from the surface of the electric screwdriver 12 in advance, so that the electric screwdriver 12 that needs to rotate with the rotating rod 17 can continue to be locked by the threaded locking head 13, so that the electric screwdriver 12 can follow the second slide 11 to slide on the Y-axis 9.

[0036] Furthermore, a downward pressure area 1601 is provided on the top of the clamping plate 16, and the Z-axis rod 4 is detachably and movably connected to the limited height circle 14. The top of the limited height circle 14 is fixedly connected to a first spring 15, and an elastic seat is fixedly installed on the top of the first spring 15. The downward pressure area 1601 and the elastic seat are engaged to prevent the clamping plate 16 from moving excessively, thereby causing the electric screwdriver 12 to contact the surface of the workpiece and cause impact damage.
