[0024] See also Figure 1-4The present invention provides a technical solution: a new type of high-precision clamping and positioning tool, including a base 1 and a slide rail 2 fixed on the base 1, and also including a clamping mechanism slidably set on the base 1 through the slide rail 2. The clamping mechanism includes a clamping assembly 3 symmetrically arranged on both sides of the slide rail 2 in the length direction. The clamping assembly 3 includes a slide 31 slidably set on the slide rail 2, a base 32 set on the top of the slide 31, and a clamping block 33 set on the top of the base 32. Fixing bolts 4 are symmetrically provided on both sides of the two groups of bases 32. A tension spring 5 is connected between the two fixing bolts 4 on the same side of the two bases 32. A base column 6 is provided on the base 1 between the two slides 31. The slide rails 2 in this application are symmetrically arranged in two groups. The base column 6 is also provided between the two groups of slide rails 2. The bottom of the base column 6 is fixed to the base 1 by a pin shaft. The top of the base column 6 is provided with a precision plate 7 for horizontal rotation. The two ends of the precision plate 7 in the length direction extend to the top of the slide 31 respectively. The precision plate 7 is provided with a connecting rod 8 above the slides 31 on both sides. The bottom end of the connecting rod 8 extends into the slide 31. The slide 31 is provided with a sliding groove 9 for the connecting rod 8 to slide. The sliding direction of the connecting rod 8 in the sliding groove 9 is perpendicular to the sliding direction of the slide 31 on the slide rail 2.

[0025] Specifically, the base 32 includes a fixed seat 321 and an adjusting seat 322. The adjusting seat 322 is arranged on a side of the fixed seat 321 away from the base column 6. The fixed seat 321 is located on one side of the adjusting seat 322 and is provided with multiple groups of guide holes 10. The corresponding guide holes 10 on the adjusting seat 322 are provided with guide rods 11. The adjusting seat 322 is slidably arranged on the fixed seat 321 through the cooperation of the guide rods 11 and the guide holes 10. The fixing bolts 4 are all arranged on the adjusting seat 322. The fixed seat 321 is provided with a driving component for driving the adjusting seat 322 to slide horizontally. The sliding adjusting seat 322 can adjust the expansion and contraction amount of the tensioning spring 5 in the initial state, thereby controlling the clamping force of the clamp 33 to clamp the LED lamp.

[0026] Specifically, a screw hole 12 is provided on one side of the fixing seat 321 close to the adjusting seat 322, and the driving assembly includes a driving bolt 13 threadedly connected to the screw hole 12, one end of the driving bolt 13 passes through the adjusting seat 322 and forms a rotational connection with the adjusting seat 322, and the driving bolt 13 and the adjusting seat 322 can be rotatably connected through a bearing connection, and the connection method is that the outer ring of the bearing is embedded and fixed in the adjusting seat 322, and the outer wall of the driving bolt 13 is fixed in the inner ring of the bearing.

[0027] Specifically, a scale rod 14 is provided in the screw hole 12, and a center hole 15 for the scale rod 14 to pass through is provided in the middle of the driving bolt 13. The scale rod 14 forms a sliding connection with the driving bolt 13 by cooperating with the center hole 15. A stud 16 is provided at the outer end of the scale rod 14, and a scale screw sleeve 17 is provided on the side of the driving bolt 13 away from the adjusting seat 322. A second screw hole 18 is provided in the middle of the scale screw sleeve 17. The scale screw sleeve 17 is threadedly connected to the stud 16 through the second screw hole 18. The end of the scale screw sleeve 17 away from the driving bolt 13 is threadedly connected to the scale bolt 19 through the second screw hole 18. It should be noted that the diameter of the stud 16 is smaller than the diameter of the scale rod 14 to avoid interference with the sliding of the driving bolt 13 and the scale rod 14. Movement, through the above method, after adjusting the sliding distance of the adjusting seat 322 on one side, the scale nut 17 can be rotated to the position where the driving bolt 13 abuts, and then the scale bolt 19 is rotated to the position where the stud 16 abuts, and then the adjusted scale nut 17 and scale bolt 19 on one side are removed, and screwed to the stud 16 on the other side. When screwing, it is necessary to screw it to the position where the scale bolt 19 abuts against the stud 16, and then by rotating the driving bolt 13 on the side to be adjusted to the position where it abuts against the scale nut 17, it can be ensured that the sliding position of the adjusting seats 322 on both sides is the same distance from the fixed seats 321 on both sides, wherein only one set of scale nut 17 and scale bolt 19 on the tooling needs to be set, and there is no need to set them on both sides.

[0028] Specifically, a collar 20 is rotatably provided on the connecting rod 8 , and the collar 20 is slidably provided in the slide groove 9 , so that the friction of the collar 20 sliding in the slide groove 9 can be reduced when the slide seat 31 slides.

[0029] Specifically, a positioning column 21 is rotatably provided on the top of the base column 6 , a bolt 22 for locking the precision plate 7 on the positioning column 21 is provided on the top of the base column 6 , and a threaded hole for the bolt 22 to be screwed is provided on the top of the base column 21 .

[0030] Specifically, the clamping block 33 is used to clamp the LED lamp, and an arc-shaped rubber 23 is provided on one end face thereof. The width of the vertical section of the arc-shaped rubber 23 gradually decreases from bottom to top, which is convenient for matching the bottom shape of the LED lamp cup. The larger width of the bottom rubber can increase the deformation, so that the clamped LED lamp is not easy to be pulled up. It should be noted that: the upper end face of one side of the clamping block 33 is used to clamp the LED lamp, and the upper part is an arc-shaped inverted conical inclined surface 24. When clamping the LED lamp cup, the LED lamp can be clamped by directly pressing down on it at the arc-shaped rubber 23.

[0031] Specifically, a plane 25 is provided on the outer wall of the base column 6 near the slide seats 31 on both sides. In the initial state, one end of the slide seat 31 abuts against the plane 25 .

[0032] A specific application example of this embodiment is:

[0033] When the device is in use, the clamping force of the clamping block 33 can be adjusted according to the size of the LED lamp of the clamping block 33; when adjusting, by rotating the driving bolt 13, the driving bolt 13 rotates to slide with the scale rod 14 and drives the adjusting seat 322 to slide on the fixing seat 321. After the adjusting seat 322 slides to the required position, the scale screw sleeve 17 is rotated to the position where it abuts against the driving bolt 13, and then the scale bolt 19 is rotated until it abuts against the outer end face of the stud 16; then the scale screw sleeve 17 is removed from the stud 16, and the disassembled scale screw sleeve 17 is screwed to the stud 16 on the side of the adjusting seat 322 that has not been adjusted temporarily, and the scale screw sleeve 17 is rotated until the end of the scale bolt 19 abuts against the outer end face of the stud 16, and then the driving bolt 13 is rotated to the outer end and the scale screw sleeve 17 abuts against each other, at this time, the adjustment seats 322 on both sides can be at the same position from the corresponding fixed seats 321, ensuring that the clamping forces of the clamping blocks 33 on the LED lamp are the same. When the LED lamp needs to be clamped, it is only necessary to place the lamp cup of the LED lamp at the joint of the arc-shaped inverted cone slope 24, and then press down the LED lamp, so that the sliding seats 31 on both sides can be slid toward the side away from each other and opened. When the LED lamp is pressed down to the arc-shaped rubber 23, the LED lamp can be clamped by the clamping block 33 under the tension of the tensioning spring 5, and the lamp holder can be installed on the neutral wire and the live wire and riveted. Through the setting of this tooling, the LED lamp can be clamped quickly, and the operator does not need to fix the LED lamp with one hand and then rivet the lamp holder to the neutral wire and the live wire, which facilitates operation and greatly speeds up operation efficiency.
