Description

Technical Field

[0001] The utility model relates to the technical field of clamping tools, and particularly relates to a clamping tool for spherical drilling. Background Technique

[0002] When drilling a spherical part traditionally, it is necessary to clamp it with a tooling fixture to ensure its stability during the drilling process, avoid slipping during drilling, and thus prevent processing failure and part scrapping.

[0003] However, many clamping tools clamp the sphere from both sides, and the clamping surfaces are arc-shaped. Although they can achieve the clamping effect, the clamping stability after clamping is relatively weak in the clamping method. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a clamping tool for spherical drilling, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A clamping tool for spherical drilling includes clamping blocks. The number of the clamping blocks is four. Arc-shaped grooves are respectively formed in the clamping blocks. Processing grooves are respectively formed at the centers of the arc-shaped grooves of the clamping blocks. Hole-bearing ear blocks are respectively fixed on the outer sides of the clamping blocks. Adjusting rods are respectively inserted through between two perpendicular hole-bearing ear blocks. External spiral teeth are respectively arranged on the outer walls of the ends of the adjusting rods far away from the lower hole-bearing ear blocks. Spiral tooth grooves are respectively arranged on the inner walls of the upper hole-bearing ear blocks. U-shaped rods are respectively arranged at the front and rear ends of the lower two clamping blocks. Sliders are respectively fixed at the two bottom ends of the lower two clamping blocks. Adjusting screws are respectively threadedly connected to the sliders. Slide rods are respectively fixed on the tops of the lower clamping blocks. Slide grooves are respectively formed in the upper clamping blocks at the positions of the slide rods.

[0007] Preferably, the adjusting rods are respectively threadedly connected to the spiral tooth grooves on the inner walls of the upper hole-bearing ear blocks through the external spiral teeth.

[0008] Preferably, the ends of the adjusting rods far away from the external spiral teeth are respectively rotatably connected to the inner walls of the lower hole-bearing ear blocks.

[0009] Preferably, the outer diameter sizes of the slide rods respectively match the inner diameter sizes of the slide grooves, and the slide rods are respectively inserted into the slide grooves at the matching positions and are slidably connected thereto.

[0010] Preferably, the sliders are sleeved on the outer walls of the U-shaped rods and are slidably connected thereto. The ends of the adjusting screws inserted into the sliders respectively contact the outer walls of the U-shaped rods.

[0011] Preferably, flange feet are fixed to both ends of the bottom of the U-shaped rod.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. The sphere can be placed in the arc grooves of the four clamping blocks. The four clamping blocks form a four-side clamping method for it through the arc grooves. Compared with the traditional two-end clamping method, it has a better clamping effect and stronger clamping stability.

[0014] 2. The adjusting rod is threadedly connected to the internal thread groove of the upper perforated ear block through external threads. The sliding rod of the upper clamping block is slidably connected in the sliding groove, so that when the adjusting rod rotates, the upper clamping block can rise, so as to be away from the lower clamping block. This is the adjustment and separation of the two upper clamping blocks and the two lower clamping blocks. The two lower clamping blocks adjust the distance between each other by sliding the sliders on the U-shaped rod, and the adjusting screw rotates to clamp the U-shaped rod, so as to obtain a limit, and then the four clamping blocks can be opened in an explosive manner, and then the spherical part can be placed into the arc groove, and then through adjustment, the four clamping blocks can clamp it, achieving convenient clamping for loading and unloading work.

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Such as Figures 1-4As shown in the figure, a clamping tooling for spherical drilling includes clamping blocks 1. The number of clamping blocks 1 is four. Arc-shaped grooves 3 are all drilled on the clamping blocks 1. Processing grooves 2 are all drilled at the positions of the clamping blocks 1 at the centers of the arc-shaped grooves 3. Holed ear blocks 6 are all fixed on the outer sides of the clamping blocks 1. Adjusting rods 7 are all inserted through between two mutually perpendicular holed ear blocks 6. External screw teeth 13 are all arranged on the outer walls of the ends of the adjusting rods 7 far away from the lower holed ear blocks 6. Screw tooth grooves 12 are all arranged on the inner walls of the upper holed ear blocks 6. U-shaped rods 8 are all arranged at the front and rear ends of the lower two clamping blocks 1. Slide blocks 9 are all fixed at the two bottom ends of the lower two clamping blocks 1. Adjusting screws 10 are all threadedly connected to the slide blocks 9. Slide rods 4 are all fixed on the tops of the lower clamping blocks 1. Slide grooves 5 are all drilled at the positions of the upper clamping blocks 1 where the slide rods 4 are located.

[0022] Specifically, the adjusting rods 7 are respectively threadedly connected to the screw tooth grooves 12 on the inner walls of the upper holed ear blocks 6 through the external screw teeth 13. The ends of the adjusting rods 7 far away from the external screw teeth 13 are respectively rotatably connected to the inner walls of the lower holed ear blocks 6. The outer diameter sizes of the slide rods 4 respectively match the inner diameter sizes of the slide grooves 5, and the slide rods 4 are respectively inserted into the slide grooves 5 at the matching positions and are slidably connected thereto. When the adjusting rods 7 rotate, the distance between the upper clamping blocks 1 and the lower processing grooves 2 can be adjusted by means of the threaded connection between the external screw teeth 13 and the screw tooth grooves 12 and the sliding of the slide rods 4 in the slide grooves 5.

[0023] Specifically, the slide blocks 9 are sleeved on the outer walls of the U-shaped rods 8 and are slidably connected thereto. The ends of the adjusting screws 10 inserted into the slide blocks 9 respectively contact the outer walls of the U-shaped rods 8. The clamping of the U-shaped rods 8 by the adjusting screws 10 makes the slide blocks 9 unable to slide on the U-shaped rods 8, thereby achieving the limiting effect.

[0024] Specifically, flange feet 11 are all fixed at the two bottom ends of the U-shaped rods 8, which is convenient for fixing the U-shaped rods 8 on the workbench.

[0025] Working principle: The sphere can be placed in the arc-shaped grooves 3 of the four clamping blocks 1. The four clamping blocks 1 form a four-side clamping method for it through the arc-shaped grooves 3. Compared with the traditional two-end clamping method, it has a better clamping effect and stronger clamping stability. The adjusting rods 7 are threadedly connected to the screw tooth grooves 12 on the inner walls of the upper holed ear blocks 6 through the external screw teeth 13. The slide rods 4 of the upper clamping blocks 1 are slidably connected in the slide grooves 5. When the adjusting rods 7 rotate, the upper clamping blocks 1 can rise, so as to be far away from the lower clamping blocks 1. This is the adjustment and separation of the upper two clamping blocks 1 and the lower two clamping blocks 1. The lower two clamping blocks 1 adjust the distance between each other by sliding the slide blocks 9 on the U-shaped rods 8, and the U-shaped rods 8 are clamped by rotating the adjusting screws 10, thereby achieving limiting. Furthermore, the four clamping blocks 1 can be presented in an exploded-open manner, and then the spherical part can be placed into the arc-shaped groove 3. Subsequently, the four clamping blocks 1 are adjusted to clamp it, achieving convenient loading and unloading work for clamping.
