Description

Technical Field

[0001] The utility model relates to the technical field of processing tooling equipment, in particular to a turning tooling for a worm seat. Background Technique

[0002] In the past, when boring a hole in a worm seat, it was necessary to first place the worm seat on a lathe. After adjusting the axis of the circular hole to be machined on it to be the same as the axis of the lathe spindle, then fix the worm seat on the lathe, and then start the lathe to bore the hole. This is very troublesome. Especially for batch processing of worm seats, it is necessary to adjust one by one, which is time-consuming and laborious. Moreover, due to the special structural form of the worm seat, even if the axis of the circular hole to be machined at one end of the worm seat is adjusted to be the same as the axis of the lathe spindle, it is very difficult to ensure that the axis of the circular hole to be machined at the other end of the worm seat is the same as the axis of the lathe spindle.

[0003] The utility model with the application number 202021744703.2 discloses a turning tooling for a worm seat, which is installed on a lathe to assist in machining the worm seat; the tooling includes a worm seat connecting plate and a clamping shaft. One end of the worm seat connecting plate is welded with a welding transition block. The clamping shaft is horizontally placed on the welding transition block and is welded to the welding transition block. One end is a clamping end, and the clamping end extends out of the worm seat connecting plate by a section; the worm seat is fixedly connected to the worm seat connecting plate, and the axis of the circular hole to be machined on it is the same as the axis of the clamping shaft; the tooling with the fixedly connected worm seat is placed on the lathe, and the clamping end of the clamping shaft is clamped by the three-jaw chuck of the lathe, that is, the axis of the clamping shaft is the same as the axis of the main shaft of the lathe; the axis of the circular hole to be machined on the worm seat is the same as the axis of the main shaft of the lathe. The design is reasonable and the structure is simple. Using the above tooling to assist in machining the worm seat is convenient, fast, and can effectively improve the efficiency of batch processing.

[0004] The turning tooling for a worm seat disclosed in the above document has the following defects: during the use of the tooling, when it is necessary to clamp and fix the worm seat through the tooling, the tooling is a fixed structure and cannot clamp and fix workpieces of different models, reducing the flexibility of the tooling.

[0005] It can be seen that the existing turning tooling for a worm seat does not have the function of flexibly clamping worm seats of different models, and it is necessary to improve the existing deficiencies to provide a function that can clamp worm seats of different models. Content of the Utility Model

[0006] The purpose of the utility model is to provide a turning tooling for a worm seat to at least solve to some extent the problems put forward in the above background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to a turning processing tooling for a worm seat, which comprises a fixing structure and a clamping structure. The clamping structure is installed on the inner wall of the fixing structure. The fixing structure comprises a fixing frame. A sealing block is installed on the inner wall of the top of the fixing frame. A sliding rod is slidably connected to the inner wall of the sealing block. A blocking block is installed at the top end of the sliding rod. Fixing rods are arranged on the outer walls of both sides of the bottom of the blocking block. The bottom ends of the two fixing rods are slidably connected to the inner wall of the fixing frame. Clamping blocks are sleeved on the outer walls of the two fixing rods. Compression springs are arranged on both sides of each of the two fixing rods close to the clamping blocks. The purpose of such a setting is that during the use of this processing tooling, the worm seat is placed on the fixing frame, the blocking block is held by hand and pulled upward. The blocking block drives the sliding rod to slide upward in the sealing block. The sliding rod drives the bottom rod and the clamping block to move upward. The clamping block drives one end of the rotating clamp to rotate upward. When the rotating clamp rotates on the fixing block, when the other end of the rotating clamp rotates backward, it drives another clamping block to move backward. The other clamping block drives the positioning rod to move inward. The bottom end of the clamping rod is fixed to the fixing frame by bolts. When the positioning rod moves backward, it drives the handle rod to squeeze the clamping rod to move towards the workpiece. The clamping rod presses against one side of the workpiece. The clamping block is pulled upward. The clamping block squeezes the upper compression spring to contract. Then the compression spring is placed on the top of the workpiece. The compression spring drives the compression spring to move downward to clamp the top of the workpiece through the rebound of the compression spring. The bottom compression spring supports the clamping block, so that it can be automatically reset, improving the flexibility of this tooling.

[0009] Further, a bottom plate is arranged on the lower surface of the fixing frame. The bottom end of the sliding rod extends into the fixing frame. A bottom rod is arranged at the bottom end of the sliding rod. A clamping block is installed at the bottom end of the bottom rod. The purpose of such a setting is that during the use of this processing tooling, the sliding rod drives the bottom rod and the clamping block to move upward. The clamping block drives one end of the rotating clamp to rotate upward.

[0010] Further, a fixing block is arranged on one inner wall of the fixing frame. A rotating clamp is rotatably connected to the outer wall of the fixing block. The clamping block is clamped on one inner wall of the rotating clamp. The purpose of such a setting is that during the use of this processing tooling, when the rotating clamp rotates on the fixing block, when the other end of the rotating clamp rotates backward, it drives another clamping block to move backward. The other clamping block drives the positioning rod to move inward.

[0011] Further, a limiting groove is formed on the outer wall of the sliding rod. A positioning rod is installed on one inner wall of the fixing frame. One end of the positioning rod extends to the outer wall of one end of the rotating clamp through the limiting groove. The purpose of such a setting is that during the use of this processing tooling, when the sealing block moves downward, the sealing block has no influence on the positioning rod through the limiting groove.

[0012] Further, a clamping block is installed at one end of the positioning rod. The clamping block is clamped on the outer wall of the other side of the rotating clamp. A clamping rod is installed on the outer wall of the positioning rod, and a handle rod is provided at the other end of the positioning rod. The purpose of this setting is that during the use of this processing tooling, the other clamping block drives the positioning rod to move inwards. The bottom end of the clamping rod is fixed on the fixing frame by bolts. When the positioning rod moves backward, it drives the handle rod to squeeze the clamping rod to move towards the workpiece.

[0013] Further, the top end of the clamping rod extends to the upper surface of the fixing frame, and a bolt is installed at the bottom end of the clamping rod. One end of the bolt is threadedly connected to the inner wall of the fixing frame. The purpose of this setting is that during the use of this processing tooling, the bottom end of the clamping rod is fixed on the fixing frame by bolts. When the positioning rod moves backward, it drives the handle rod to squeeze the clamping rod to move towards the workpiece, and the clamping rod abuts against one side of the workpiece.

[0014] The utility model has the following beneficial effects:

[0015] Through the arrangement of the compression spring and the sliding rod in the utility model, the sliding rod drives the bottom rod and the clamping block to move upwards. The clamping block drives one end of the rotating clamp to rotate upwards. When the other end of the rotating clamp rotates backward, it drives the other clamping block to move backward. When the positioning rod moves backward, it drives the handle rod to squeeze the clamping rod to move towards the workpiece, and the clamping rod abuts against one side of the workpiece. Pull the clamping block upwards, and the clamping block squeezes the upper compression spring to contract. Then place the compression spring on the top of the workpiece. The compression spring drives the compression spring to move downwards to clamp the top of the workpiece through the rebound of the compression spring. The bottom compression spring supports the clamping block, enabling automatic reset, and improving the flexibility of this tooling.

[0016] Of course, when implementing any product of the utility model, it is not necessarily required to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom ends of the two fixed rods 210 are slidably connected to the inner wall of the fixing frame 102. Clamping blocks 212 are sleeved on the outer walls of the two fixed rods 210. Compression springs 211 are provided on both sides of the two fixed rods 210 close to the clamping blocks 212. The purpose of such a setting is that during the use of this processing tool, the worm seat is placed on the fixing frame 102, the stop block 205 is held by hand and pulled upward. The stop block 205 drives the sliding rod 202 to slide upward in the sealing block 201. The sliding rod 202 drives the bottom rod 204 and the clamping block 209 to move upward. The clamping block 209 drives one end of the rotating clamp 105 to rotate upward. When the rotating clamp 105 rotates on the fixed block 104, the other end of the rotating clamp 105 rotates backward and drives another clamping block 209 to move backward. Another clamping block 209 drives the positioning rod 206 to move inward. The bottom end of the clamping rod 208 is fixed to the fixing frame 102 by a bolt 200.
