DETAILED DESCRIPTION
[0028] In one embodiment 1 of the present utility model, Figure 1 As shown, a manual rotary indexing vise is provided, which includes a base 6, a shaft seat 5, a clamp body 1, an active jaw 2, a nut seat 3, a screw rod 4 and a gear box 25. The base 6 is used to install the entire rotary indexing vise on other workstations or equipment. The screw rod 4 drives the active jaw to move left and right to adjust the size of the clamping opening, thereby clamping the parts.
[0029] Furthermore, if Figure 1-2As shown: the shaft seat 5 supports the left side of the pliers body through the short shaft 61, and the long shaft 34 is connected to the bearing 32 and the bearing 38 in the gear box 25 to support the right side of the pliers body. One end of the long shaft 34 is connected to the handle shaft 17 and extends out of the gear box. The handle shaft 17 is equipped with a handle 18 / 22, and the handle can rotate left and right. A bearing seat is arranged inside the right side of the gear box for installing the bearing 32. An end cover 14 is arranged on the right side of the gear box. The end cover 14 is connected to the gear box 25 with screws. A clamping screw 20 and a boss are arranged on the end cover 14 for installing a second rotatable clamping ring 23. The bayonet on the clamping ring is used to clamp the handle 22, and the handle drives the pliers body to fuzzily position the preset angle.
[0030] Furthermore, if Figure 1 As shown, a bracket 15 is arranged on the right side of the gear box 25, a first rotatable clamping ring 21 is installed at one end of the bracket, and a removable clamping ring 16 is installed at the other end. The first rotatable clamping ring 21 is used to fuzzily position the preset angle of the caliper body, and the clamping ring 16 is used to fuzzily position the fixed angle of the caliper body.
[0031] Furthermore, if Figure 2-7 As shown, a keyway is provided on the long shaft 34, and a plurality of gears 71 with keyways are installed on the long shaft 34. A flat key is installed in the keyway to prevent the gears and the shaft from relative movement. Support plates 77 are installed on both sides of the gear 71. The two support plates form a group of short connecting rods 78 clamped in the middle. The short connecting rod and the support plate are connected by a pin shaft 65. The short connecting rod is connected to a movable tooth claw 76 by the same pin shaft 65. The movable tooth claw 76 is connected to the long connecting rod 74 through the pin shaft. The other end of the long connecting rod 74 is connected to the elbow rocker arm 73. One end of the elbow rocker arm is connected to the rocker arm seat 28 through a pin shaft 66, and the other end is connected to the lower small connecting rod 47. The other end of the lower small connecting rod is connected to the left quick locking handle 7 and the right quick locking handle 9. The other ends of the left quick locking handle 7 and the right quick locking handle 9 are connected to the lower hinge seat 12. The lower hinge seat is installed on the gear box. By pulling the quick locking handle, the movable claw can be separated from the gear and meshed. The tightness of the engagement between the movable claw and the gear is adjusted by the lower adjusting screw 68 on the elbow rocker arm.
[0032] Furthermore, if Figure 5-10 As shown, the long arm tooth claw 75 is connected to the elbow connecting rod 51 through the pin 62, and the other end of the elbow connecting rod 51 is connected to the rocker arm 26 through the pin. One end of the rocker arm 26 is connected to the rocker arm seat 28 through the pin 66, and the other end is connected to the quick locking handle 8. The other end of the quick handle 8 is connected to the upper small connecting rod 46, and the other end of the upper small connecting rod 46 is connected to the upper hinge seat 13. By pulling the quick locking handle 8, the rocker arm tooth claw can be separated or engaged with the gear, and the tightness of the engagement of the long arm tooth claw 75 with the gear is adjusted by the upper adjusting screw 69 of the upper hinge seat 13.
[0033] Furthermore, if Figure 6-10As shown, two support plates form a group, a rotating shaft 80 is set in the middle, a support screw 79 is set on the rotating shaft, and the support screw 79 is installed on the upper hinge seat 13. Rotating the support screw can drive the support plate to rotate around the axis, and the support plate rotates with the movable claw through the short connecting rod, thereby changing the angle of the movable claw.
[0034] An embodiment 2 of the utility model provides a method for using a manual rotary indexing vise, which includes loosening all the quick locking handles described in embodiment 1, replacing the clamping ring 16 with a required number of bayonet holes, such as a clamping ring divided into three, four, five or six equal parts, turning the handle 18 to place it on the required bayonet hole, and turning the corresponding quick locking handle 8 to lock the indexing. At this time, the position of the clamp body is the required angle. Because it is a gear indexing, the minimum indexing value is 360 divided by the number of teeth of the gear. If 72 teeth are used, the minimum indexing value is 5°, and if 60 teeth are used, the minimum indexing value is 6°, which is controlled by the quick locking handle 8. If other indexing values are required, they are controlled by the left quick locking handle 7 and the right quick locking handle 9. Loosen the quick locking handle, turn the first rotatable clamp ring 21 or the second rotatable clamp ring 23 to the required angle and lock it, pull the handle 22 to snap onto the rotatable clamp ring bayonet, pull the corresponding left quick locking handle 7 or right quick locking handle 9 to slightly tighten, at this time, the angle of the pliers body is not necessarily the required angle, and the support screw 44 or 45 needs to be adjusted to push the pliers body to the required angle, and then lock the quick locking handle to the required angle. As described in Example 1, it can be seen that the degree adjustment range of the support screw only requires the degree between the two teeth of the gear. If the gear has 72 teeth, it only needs to be adjusted by 5°, and if the gear has 60 teeth, it only needs to be adjusted by 6° to obtain any degree.
[0035] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications, equivalent substitutions and improvements made to the technical solutions of the present invention by ordinary technicians in this field should be included in the protection scope determined by the claims of the present invention.
