Description

Technical Field

[0001] The utility model relates to the field of screw installation equipment, in particular to a charger installation screw mechanism. Background Art

[0002] In the prior art, when screwing a charger, it is necessary to additionally use a clamping and positioning mechanism to clamp and position the charger, and then use a screw machine to tighten the screw into the threaded hole on the charger. In this process, the clamping and positioning accuracy of the charger by the clamping and positioning mechanism often directly affects the efficiency and accuracy of screw assembly, and improving the clamping and positioning accuracy often comes at the expense of the convenience of loading and unloading. The size of the clamping and positioning mechanism is designed to be too compact, which does not improve the assembly efficiency.

The clamping mechanism applied to the automatic screw tightening machine can facilitate the removal of the workpiece after screwing from the clamping cavity and the placement of the workpiece without screwing into the clamping cavity, thereby ensuring the clamping and placing speed of the workpiece, thereby improving the efficiency of screwing. However, the clamping mechanism used in the automatic screw-tightening machine can only perform positioning and clamping, and does not have the function of flipping the workpiece, which limits the area of ​​the workpiece for screwing.

[0020] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0021] Example 1

[0022] This embodiment provides a charger installation screw mechanism, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes an automatic screw tightening unit. A front-to-back linear module 4 is arranged below the automatic screw tightening unit, and a pair of rotating support seats 15 are slidably arranged on the front-to-back linear module 4. A pressing cylinder, an oblique tightening cylinder 17 and a plurality of L-shaped positioning blocks 12 are rotatably arranged between the pair of rotating support seats 15 through a rotating motor 9. The oblique tightening cylinder 17 and the plurality of L-shaped positioning blocks 12 enclose a positioning area for placing the charger 10.

[0023] Specifically, in this embodiment, the rotary motor 9 is disposed on one of the rotary support seats 15. An active rotary seat plate 13 is connected to the rotary shaft of the rotary motor 9, and a group of L-shaped positioning blocks 12 are disposed on the active rotary seat plate 13.

[0024] A passive rotating seat plate 16 is rotatably arranged on the other rotating support seat 15 via a connecting shaft 18. The oblique tightening cylinder 17, the pressing cylinder and one of the L-shaped positioning blocks 12 are respectively arranged on the passive rotating seat plate 16. An oblique tightening block 14 is installed at the telescopic end of the oblique tightening cylinder 17, and a vertical groove is provided on the oblique tightening block 14.

[0025] like Figure 1 As shown, in this embodiment, a pair of the rotating support seats 15 are connected to a movable base 5 at the bottom. The movable base 5 is connected to a connecting and fixing plate 19 at the bottom, and the connecting and fixing plate 19 is slidably matched with the front-rear linear module 4.

[0026] like Figure 2 and Figure 3 As shown, in order to facilitate loading and unloading operations and avoid interference during loading and unloading, the clamping cylinder is provided with a pressure rod 11 that can be raised and lowered and rotated. For the convenience of support, a support table 1 and a support platform 2 for supporting the forward and backward linear module 4 are also provided below the automatic screw tightening unit.

[0027] In order to realize multi-station screw driving, the automatic screw tightening unit includes a gantry support frame 3 arranged on the support table 1, a horizontal linear module 6 slidably arranged on the top of the gantry support frame 3, a vertical linear module 7 slidably arranged on the horizontal linear module 6, and a screwdriver rotatably arranged at the lower end of the vertical linear module 7, and a screw feeder 8 is arranged on the support table 2.

[0028] Example 2

[0029] This embodiment provides a charger installation screw mechanism, which differs from Embodiment 1 mainly in that, in this embodiment, in order to improve the screw driving efficiency and realize continuous operation, a pair of forward and backward linear modules are arranged under the automatic screw tightening unit.

[0030] Example 3

[0031] This embodiment provides a charger installation screw mechanism, which differs from Embodiment 1 mainly in that, in this embodiment, in order to improve the efficiency of screw driving and realize continuous operation, a plurality of forward and backward linear modules arranged parallel to each other are arranged under the automatic screw tightening unit.

[0032] Specifically, when installing screws on a charger using a charger installation screw mechanism provided by the utility model, the specific operating steps are as follows:

[0033] First, place the charger between the active rotating seat plate and the passive rotating seat plate, and use three L-shaped positioning blocks to pre-position the charger.

[0034] After placement, start the screw machine. The clamping cylinder clamps the product. At the same time, the oblique clamping cylinder drives the oblique clamping block to clamp the other corner of the charger obliquely, thereby clamping and positioning the charger. Since the oblique clamping cylinder has a short stroke, the product is positioned before the clamping cylinder is in place, and then the clamping cylinder is used to clamp the charger to prevent the charger from falling during rotation.

[0035] Then, the charger after tightening and positioning is driven to the bottom of the gantry support frame by moving the linear module forward and backward, and the screw machine is driven by the horizontal linear module and the vertical linear module to move and tighten the screws in the threaded holes. Finally, the active rotating seat plate and the passive rotating seat plate are driven by the rotating motor to rotate, so as to complete the installation of screws on the side of the charger.

[0036] Specifically, the pressing cylinder and the oblique pressing cylinder use the same electromagnetic valve to control the air intake, so their ventilation time is the same. The pressing cylinder and the oblique pressing cylinder are equipped with throttle valves to control the cylinder speed. In addition, the stroke of the pressing cylinder is short, and the speed of the oblique pressing cylinder is increased to ensure that the product is positioned before pressing each time. After the product is placed, there is a detection switch to detect whether there is a product to determine whether to proceed to the next step of screwing.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
