Description

Clamp for gear production

Technical Field

The invention relates to the technical field of gear machining equipment, in particular to a clamp for gear production.

Background

The jig is a device for fixing a processing object to occupy a correct position for receiving construction or inspection in a machine manufacturing process. In a broad sense, any device used to quickly, conveniently and safely mount a workpiece at any stage in a process may be referred to as a jig. Such as welding jigs, hobbing jigs, assembly jigs, machine tool jigs, and the like. Among them, the machine tool clamp is the most common, and is often referred to as a clamp for short. When a workpiece is machined on a machine tool, the workpiece needs to be assembled (positioned) and firmly clamped (clamped) before machining in order to enable the surface of the workpiece to meet the technical requirements of the size, the geometric shape, the mutual position precision with other surfaces and the like specified in the drawing.

The spring clamping chip collecting type tooth protection gear drilling clamp comprises a base box, a positioning ring fixedly connected to the base box, and support legs fixedly connected to the lower portion of the base box, wherein the base box is of a hollow cuboid structure, and the top of the base box is provided with a chip falling hole and a clamp support; a spring pressing device is arranged on the positioning ring; and the spring pressing device is provided with a clamp head.

When the gear to be machined is fixed, the gear on the gear is matched with the gear on the clamp head, and the fixing and pressing device is required to be adjusted, so that great inconvenience is brought.

Disclosure of Invention

Technical problem to be solved

In order to solve the problems in the prior art, the invention provides a fixture for gear production, which can ensure the stability of fixation and is convenient to fix.

(II) technical scheme

In order to achieve the purpose, the invention adopts the main technical scheme that: including workstation, chip falling hole, position circle, closing device and anchor clamps head, the anchor clamps head is provided with two about chip falling hole bilateral symmetry, the anchor clamps head is the arc structure, the anchor clamps head is close to one side inner wall each other and is provided with the location tooth group, the anchor clamps head rest is close to chip falling hole one side still welded fastening has the backup pad that is used for the arc structure that the counter gear supported.

Preferably, the pressing device is a telescopic cylinder, and the workbench is further provided with a controller.

Preferably, one side of the clamp head, which is far away from each other, is fixedly welded with a sliding rod, and the sliding rod penetrates through the positioning ring and is in sliding connection with the positioning ring.

Preferably, the chip falling hole, the positioning ring, the clamp head and the supporting plate are all arranged concentrically.

(III) advantageous effects

The invention provides a clamp for gear production. The method has the following beneficial effects:

(1) when need be fixed to processing gear, at first start telescopic cylinder through the controller, stop when the gear of processing can be placed in the backup pad for at first, then match the overhead gear train of waiting to process the gear teeth and anchor clamps, after the matching is good, start telescopic cylinder again and press from both sides tightly fixedly, compare traditional fixed mode, it is simpler, convenient.

(2) When the gear to be processed is processed, the vibration generated by the gear can be shared by the sliding rod, and the load of the pressing device is reduced.

Drawings

FIG. 1 is a front view of the present invention;

FIG. 2 is a view showing the connection structure of the head and the supporting plate of the clamping apparatus according to the present invention.

In the figure: 1. a work table; 2. chip falling holes; 3. positioning rings; 4. a pressing device; 5. a clamp head; 6. positioning the tooth group; 7. a support plate; 8. a controller; 9. a slide bar.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-2, the fixture for gear production in this embodiment includes a workbench 1, two chip falling holes 2, a positioning ring 3, a pressing device 4, and a fixture head 5, where the fixture head 5 is provided with two chip falling holes 2 in bilateral symmetry, the fixture head 5 is an arc-shaped structure, the fixture head 5 is provided with a positioning tooth group 6 on the inner wall close to one side of the fixture head 5, and one side of the fixture head 5 close to the chip falling holes 2 is further welded and fixed with a supporting plate 7 of the arc-shaped structure for supporting a gear. When needing to fix the processing gear, at first adjustment closing device 4 guarantees that the gear of processing can be placed in backup pad 7 for the gear of processing, then matches the tooth of treating the processing gear and overhead gear train 6 of anchor clamps, and after the matching is good, starts telescopic cylinder again and presss from both sides tightly fixedly, compares traditional fixed mode, and is simpler, convenient.

Further, the pressing device 4 is a telescopic cylinder, and the workbench 1 is also provided with a controller 8.

Furthermore, a sliding rod 9 is fixedly welded on one side, away from each other, of the fixture head 5, and the sliding rod 9 penetrates through the positioning ring 3 and is in sliding connection with the positioning ring 3. When the gear to be processed is processed, the vibration generated by the gear can be shared by the sliding rod 9, and the load of the pressing device is reduced.

Furthermore, the chip falling hole 2, the positioning ring 3, the clamp head 5 and the supporting plate 7 are all concentrically arranged.

The working principle is as follows: when needing to fix the processing gear, at first start telescopic cylinder through controller 8, the gear of processing for the generation can be placed and stop when in backup pad 7, then to wait to process the gear teeth and the overhead gear train 6 matching of anchor clamps, after the matching is good, start telescopic cylinder again and press from both sides tightly fixedly, compare traditional fixed mode, it is simpler, convenient, wait that the gear of processing adds man-hour, the vibrations that the gear produced can be shared by slide bar 9, reduce closing device's load.
