[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0024] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Example

[0026] First, the workpiece to be drilled with screw holes needs to be placed between the two clamping members provided on the processing table 1, and the two clamping members are manually operated to clamp and fix the workpiece, and then the punching device 5 connected to the driving lifting structure is lowered by the handle to drill the top screw hole of the workpiece. The lack of linkage with the lifting structure can realize the clamping structure of the workpiece without manual intervention, resulting in a long manual clamping operation time during drilling, which greatly reduces the efficiency of drilling screw holes;

[0027] To do this, see Figure 1-5 The utility model provides a high-efficiency screw-driving fixture, comprising:

[0028] A processing table 1 and a punching device 5, wherein an n-shaped support frame 2 is fixedly connected to the top of the processing table 1, a vertical plate 21 is fixedly connected to the rear side wall of the n-shaped support frame 2, and the vertical plate 21 is connected to the punching device 5 through a lifting transmission structure 4, and a sliding groove with an I-shaped structure in the longitudinal vertical section is provided through the top of the n-shaped support frame 2, and two symmetrically arranged sliding seats 22 are slidably connected in the sliding groove, and the longitudinal vertical sections of the sliding seats 22 are all I-shaped structures, and the transverse vertical sections of the sliding seats 22 are all L-shaped structures, and two symmetrically arranged clamping seats 23 are also slidably connected in the sliding groove, and the opposite ends of the two clamping seats 23 are provided with V-shaped clamping brackets 231, and the longitudinal vertical sections of the clamping seats 23 are all I-shaped structures, and the clamping seats 23 are connected to the corresponding sliding seats 22 through the adjusting fixing unit 3;

[0029] It also includes a synchronous linkage clamping structure 6 which is installed on the rear side wall of the n-shaped support frame 2 and is connected to the lifting transmission structure 4 and the two sliding seats 22 .

[0030] Among them, the punching device 5 includes a punching motor 43 and a threaded punching tool fixed to the output shaft of the punching motor 43. The thickness of the sliding seat 22 is smaller than the thickness of the clamping seat 23. The bottom end of the clamping seat 23 slides on the inner bottom wall of the sliding seat 22. An inclined discharge port 11 is also provided on the processing table 1 below the n-type support frame 2. The setting of the inclined discharge port 11 can facilitate the discharge of waste materials when opening screw holes.

[0031] Further as Figure 1-4 As shown, it is worth explaining in detail that the adjustment and fixing unit 3 includes a through hole opened through the clamping seat 23, in which a hand screw 31 is movably inserted, and a plurality of screw holes 32 matching the bottom end of the hand screw 31 are opened on the inner bottom wall of the sliding seat 22, and the plurality of screw holes 32 are arranged in an equidistant array.

[0032] Among them, by adjusting the setting of the fixing unit 3, the distance between the two clamping seats 23 can be adjusted. Because the synchronous linkage clamping will always move the two sliding seats 22 towards each other at equal distances, the distance between the two clamping seats 23 can be adjusted to facilitate clamping and fixing of workpieces with different outer diameters.

[0033] Further as Figure 1-4 As shown, it is worth explaining in detail that the lifting transmission structure 4 includes a lifting channel opened on the vertical plate 21, and a lifting seat 41 with an I-shaped cross-section is slidably connected in the lifting channel, and the front end of the lifting seat 41 is fixed to the punching device 5. A screw 42 is threadedly connected to the lifting seat 41, and both ends of the screw 42 are rotatably connected in the lifting channel. The top end of the screw 42 extends to the top of the vertical plate 21 and is fixed to the output shaft of the motor 43. The motor 43 is fixed to the top of the vertical plate 21.

[0034] Further as Figure 1-4 As shown, it is worth explaining in detail that in order to achieve the purpose of actively clamping and fixing the workpiece without manual interference under the linkage action of the above-mentioned lifting transmission structure 4, a synchronous linkage clamping structure 6 is set, including a push-pull rod 61 hinged at the rear end of the lifting seat 41, and the bottom end of the push-pull rod 61 is hinged to the top of the moving bar 62. The moving bar 62 is slidably sleeved on the outside of two symmetrically arranged guide rods 63. The front ends of the guide rods 63 are fixed to the rear side wall of the n-type support frame 2. The bottom end of the moving bar 62 is fixed to two symmetrically arranged transmission columns 64. The bottom ends of the transmission columns 64 are movably overlapped in the transmission channel 66 opened on the linkage plate 65. The two transmission channels 66 are symmetrically arranged, and the cross-section of the transmission channel 66 is a "hockey stick" structure. The top edges of the two linkage plates 65 are fixed to the corresponding bottom ends of the sliding seats 22.

[0035] The width of the transmission channel 66 is equal to the diameter of the transmission column 64. When the moving bar 62 drives the two transmission columns 64 to move away from the n-shaped support frame 2, the two linkage plates 65 will move relative to each other in combination with the shape design of the transmission channel 66.

[0036] In summary: when using the screw-driving fixture, first adjust the distance between the two clamping seats 23 according to the outer diameter of the workpiece. By loosening the two hand screws 31 and cooperating with the multiple screw holes 32, the distance between the V-shaped clamping brackets 231 respectively provided on the two clamping seats 23 can be adjusted. After the adjustment is completed, the corresponding hand screws 31 can be locked into the screw holes 32, and the workpiece to be screwed is placed between the two V-shaped clamping brackets 231. Secondly, by starting the motor 43, the screw rod 42 is driven to rotate, so that the lifting seat 41 drives During the downward movement of the punching device 5, in cooperation with the action of the push-pull rod 61, the movable bar 62 is prompted to move in the direction away from the n-type support frame 2, and the two transmission columns 64 are driven to move in the corresponding transmission channels 66 respectively. Combined with the shape design of the transmission channel 66, the two linkage plates 65 can move relative to each other, and the two sliding seats 22 are prompted to move relative to each other, so that the two clamping seats 23 can actively clamp and fix the workpiece without human intervention, so that the lifting device continues to move downward to realize the setting of screw holes, thereby greatly improving the efficiency of opening screw holes.
