Description

Technical Field

[0001] The utility model relates to the technical field of automobile starter processing, in particular to a clamping tool used for processing a starter shell. Background Art

[0002] The electronic starter is what people usually refer to as a motor, also known as a starter. It drives the starter rotor to rotate by rotating the energized coil in the magnetic field, and the pinion on the rotor drives the engine flywheel to rotate, thereby driving the crankshaft to rotate and start the car. In the mechanical processing industry, using CNC machining centers to drill and mill parts is a relatively efficient processing method. When processing the existing automotive starter end cover, it is a casting, and after casting to form a blank, it needs to be processed to meet the assembly or working size requirements.

[0003] However, the existing clamping tooling for starter housing processing has the following problems during use: traditional clamping requires a larger clamping position, but due to limited space in the starter and a large processing area, the general clamping method has limited functions, which is not conducive to the stability of the processing size. There are many clamping parts that need to be fixed one by one, the process is relatively cumbersome, and the operation is very inconvenient, making it not very practical. Utility Model Content

[0004] The purpose of the utility model is to provide a clamping tool for machining a starter housing, so as to solve the related problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping tool for processing starter housing, comprising a base, a fixed shaft, a clamping platform and a starter housing, a fixed shaft is installed at the four corners of the top of the base, and a clamping platform is installed at the top of the fixed shaft, an empty groove is opened inside the clamping platform, a cylinder is installed at the bottom end of the clamping platform, and a positioning frame is installed at the output end of the cylinder, a positioning pin is arranged on the inner wall of the positioning frame, a mounting plate is installed at the top of the clamping platform, and a positioning rod is installed at one end of the mounting plate, and the outer wall of the positioning pin is hinged with a clamping frame for fixing.

[0006] The technical solution provides a clamping tool for processing a starter housing, wherein an arc-shaped slideway is provided on the inner wall of the clamping frame, and the positioning rod is adapted to the inside of the arc-shaped slideway.

[0007] The technical solution provides a clamping tool for machining a starter housing, wherein a positioning column is installed at the top of the clamping platform, and the top of the positioning column is matched with the bottom groove of the starter housing.

[0008] The technical solution provides a clamping tool for processing a starter housing, wherein a starter housing is placed on the top of the clamping platform, and an outer wall of the starter housing is tightly fitted with an outer wall of a clamping frame.

[0009] The technical solution provides a clamping tool for machining a starter housing, wherein the outer wall of the clamping frame is provided with anti-slip grooves.

[0010] Compared with the prior art, the utility model provides a clamping tool for machining a starter housing, which has the following beneficial effects:

[0011] 1. The utility model starts the cylinder to drive the positioning frame to move upward, so that the positioning frame drives the clamping frame in the positioning pin shaft to move downward. Then, the clamping frame moves downward under the action of the positioning rod, and then presses and fixes the position of the starter housing. When it needs to be released, the cylinder can be started to drive the positioning frame to move upward, so that the clamping frame is flipped upward and to one side under the action of the positioning rod, so that it does not contact the position of the starter housing, which is convenient for removing the starter housing from the position above the clamping platform.

[0012] 2. The utility model places the starter housing on the clamping platform so that the groove below the starter housing is aligned with the positioning column, which not only plays a positioning role, but also further limits left and right displacement, thereby further improving practicality.
