Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an engine bracket processing tool. Background Art

[0002] The engine bracket is generally formed by casting. Due to process limitations, there are burrs on the surface of the casting after molding, and the casting needs to be polished. At present, factories mostly use turntable automatic sandblasting machines to polish engine brackets. The structure of the turntable automatic sandblasting machine can refer to CN217648199U. The fixture structure is cleverly designed. When the turntable drives the fixture into the sandblasting cover, the contact wheel contacts the arc bar, which can drive the fixture to rotate, so that the clamped workpiece can be sandblasted evenly. However, there are still the following shortcomings in actual applications. The speed of the fixture's rotation depends on the rotation speed of the turntable. If you want to increase the speed of the fixture so that the workpiece can rotate more times and be sprayed more evenly, you can only increase the speed of the turntable. However, increasing the speed of the turntable will make it inconvenient to disassemble and assemble the workpiece without stopping the machine, which needs to be improved. Utility Model Content

[0003] In order to solve the problems mentioned in the background technology, the purpose of the utility model is to provide an engine bracket processing tool.

[0004] In order to achieve the above objectives, the technical solution of the utility model is:

[0005] The transmission shaft is connected with the transmission gear through the support frame, and the transmission gear is connected with the transmission gear through the support frame, and the transmission gear is connected with the transmission gear through the support frame, and the transmission gear is connected with the transmission gear through the support frame.

[0006] Furthermore, the outer wall of the contact wheel is covered with anti-slip rubber.

[0007] Furthermore, a protective cover is installed on the support plate, a circular hole matching the turntable is opened on the top of the protective cover, the turntable is arranged in the circular hole, a sandblasting cover is installed on the rear side of the protective cover, the sandblasting cover covers a part of the turntable, the orthographic projections of several driving rollers are all located in the orthographic projection of the sandblasting cover, the sandblasting cover is provided with a through opening corresponding to the moving path of the clamp, a door curtain is provided in the through opening, and a sandblasting mechanism is installed in the sandblasting cover.

[0008] The beneficial effect of the utility model is as follows: compared with the clamp mentioned in the background technology, the rotation speed of the rotating shaft no longer depends on the rotation speed of the turntable, but the rotation speed of the rotating shaft can be changed by changing the rotation speed of the transmission shaft 2, thereby changing the rotation speed of the clamp, ensuring that the clamp can rotate at a faster speed while the turntable rotates slowly, so that the engine bracket can be polished more evenly.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.

[0015] like Figure 1-Figure 4As shown, it includes a base 1, a support plate 12 is horizontally installed on the top of the base 1 through a support member 11, a transmission shaft 2- is vertically installed in the support plate 12 through a bearing, a circular turntable 21 is coaxially fixed to the top of the transmission shaft 2-, a plurality of rotating shafts 3 are vertically installed on the edge of the turntable 21 through a plurality of bearings, the plurality of rotating shafts 3 are uniformly arranged around the circumference of the transmission shaft 2-, a clamp 31 is fixed to the top of the rotating shaft 3, a contact wheel 32 is coaxially fixed to the bottom of the rotating shaft 3, a plurality of transmission rollers 4 are vertically installed on the rear side of the support plate 12 through a plurality of bearings, the plurality of transmission rollers 4 are uniformly arranged around a semicircular arc path concentric with the transmission shaft 2, a transmission shaft 2- is vertically installed on the front side of the support plate 12 through a bearing, a transmission wheel 51 is connected to the transmission shaft 2-, a transmission belt 6 is jointly sleeved on the transmission wheel 51 and the plurality of transmission rollers 4, a driving member 7 and a driving member 7 are respectively arranged below the support plate 12. Driving member 28, driving member 17 and driving member 28 respectively drive the transmission shaft 21 and the transmission shaft 22 to rotate. Preferably, driving member 17 and driving member 28 are both motors. Driving member 17 is fixed on the base 1, and driving member 28 is fixed on the bottom of the support plate 12. When the transmission shaft 22 rotates, the transmission belt 6 sleeved on the multiple transmission rollers 4 can drive the contact wheel 32 in contact with it to rotate. A protective cover 9 is installed on the support plate 12. A circular hole matching the turntable 21 is opened on the top of the protective cover 9. The turntable 21 is arranged in the circular hole. A sandblasting cover 10 is installed on the rear side of the protective cover 9. The sandblasting cover 10 covers a part of the turntable 21. The orthographic projections of several transmission rollers 4 are all located in the orthographic projection of the sandblasting cover 10.

[0016] In actual applications, when the clamp 31 is located outside the sandblasting cover 10, the engine bracket can be disassembled and assembled. When the turntable 21 drives the clamp 31 into the sandblasting cover 10 and the contact wheel 32 contacts the transmission belt 6, the rotating shaft 3 starts to rotate, thereby driving the clamp 31 to rotate. The rotation speed of the transmission shaft 22 can be changed according to the sandblasting requirements, thereby changing the rotation speed of the clamp 31 to achieve different grinding requirements. The rest of the working principles can be referred to CN217648199U, which will not be elaborated here.

[0017] In this embodiment, the outer wall of the contact wheel 32 is covered with anti-slip rubber, which can increase the friction between the contact wheel 32 and the transmission belt 6.
