Multipurpose machining fixing device for gear shifting shaft of motorcycle
Technical Field
The invention relates to a motorcycle accessory machining device, in particular to a multipurpose machining fixing device for a shift shaft of a motorcycle.
Background
The motorcycle gear shift shaft is a common motorcycle part and is mainly used for motorcycle gear shift. In the machining process of the gear shifting shaft, manual feeding is generally adopted for fixation, the efficiency is low, and fingers of workers are also easily injured.
Disclosure of Invention
The invention mainly solves the technical problems in the prior art, and provides a multipurpose machining fixing device for a gear shifting shaft of a motorcycle.
The technical problem of the invention is mainly solved by the following technical scheme: a
A multipurpose machining and fixing device for a gear shifting shaft of a motorcycle is characterized by comprising a driving block, a driving cylinder is arranged in the driving block, two sides of the driving block are respectively provided with a guide chute, the head of the driving block is provided with a movable notch, two ends of the movable notch are respectively provided with a rotating round hole, a rotatable chuck is respectively arranged between the rotating round holes, the tail of the driving block is provided with a movable clamping support, the clamping support comprises a connecting cross bar, the middle of the connecting cross bar is provided with a cylinder rod, two sides of the connecting cross bar are respectively provided with a push rod, the cylinder rod is connected with the driving cylinder, the chuck comprises a strip-shaped clamping bar, and the tail of the clamping bar is provided with a pair of rotating column heads, the head of the holding strip is provided with a U-shaped holding groove.
As a preferred embodiment of the invention, the clamping head is a steel casting.
The multipurpose machining fixing device for the gear shifting shaft of the motorcycle has the following advantages: when the fixing device is used, a user installs the fixing device at the downstream of the blanking device, after a blank steel bar on the blanking device is sent to a processing station, the driving cylinder is started, the push rod synchronously moves forwards in the guide sliding groove and abuts against the holding strips of the clamping heads, and meanwhile, the clamping heads simultaneously rotate inwards to firmly fix the blank steel bar, so that the subsequent machining is facilitated. After the machining is finished, the driving cylinder retreats, and the blank steel bar directly falls into a skip car below. The rotary chuck is adopted, so that the rotary chuck can adapt to blank steel bars of various sizes, and has wide processing range and good flexibility. The multipurpose machining fixing device for the gear shifting shaft of the motorcycle is simple in structure, obvious in effect, low in cost and high in practicability.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention will be more clearly and clearly defined.
As shown in fig. 1 to 4, the multipurpose machining fixture 1 for the shift shaft of the motorcycle comprises a driving block 2, a driving cylinder 24 is arranged in the driving block 2, a guiding chute 23 is respectively arranged at two sides of the driving block 2, the head of the driving block 2 is provided with a movable notch 21, two ends of the movable notch 21 are respectively provided with a rotating round hole 22, a rotatable chuck 4 is respectively arranged between the rotating round holes 22, the tail part of the driving block 2 is provided with a movable clamping bracket 3, the clamping bracket 3 comprises a connecting cross bar 31, a cylinder rod 33 is arranged in the middle of the connecting cross bar 31, two sides of the connecting bar 31 are respectively provided with a push rod 32, the cylinder rod 33 is connected with the driving cylinder 24, the chuck 4 comprises an elongated holding strip 41, a pair of rotation posts 43 are provided at the tail of the holding strip 41, and a U-shaped holding slot 42 is provided at the head of the holding strip 41.
The chuck 4 is a steel casting.
In use, as shown in fig. 1 and 2, the user mounts the fixing device downstream of the blanking unit, and after the blank steel bar on the blanking unit is fed to the processing station, the actuating cylinder 24 is actuated, and the push rod 32 is synchronously moved forward in the guide chute 23 and abuts against the holding strips 41 of the chucks 4, and simultaneously, the pair of chucks 4 are simultaneously rotated inward to firmly fix the blank steel bar, thereby facilitating the subsequent machining. After the machining is finished, the driving cylinder 24 retreats, and the blank steel bar directly falls into a skip car below.
The rotatable chuck 4 is adopted, so that the clamp can adapt to blank steel bars with different sizes, and has wide processing range and good flexibility.
The multipurpose machining fixing device for the gear shifting shaft of the motorcycle is simple in structure, obvious in effect, low in cost and high in practicability.
Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
