Quick fixing device that punches of bent axle side position
Technical Field
The invention relates to crankshaft manufacturing equipment, in particular to a crankshaft side punching and quick fixing device.
Background
A crankshaft is a common power transmission device, and includes a fan-shaped shaft cake and a hollow shaft tube. When the shaft pipe is laterally punched, three groups of clamps are needed, and the operation is rather inconvenient.
Disclosure of Invention
The invention mainly solves the technical problems in the prior art, and provides a quick fixing device for side punching of a crankshaft.
The technical problem of the invention is mainly solved by the following technical scheme:
a quick fixing device for punching on the side of a crankshaft is characterized by comprising a fixing base, wherein a detachable fixing support is arranged on the fixing base, a detachable guide seat is arranged on the fixing support, a sliding notch is formed in the side wall of the fixing base, four positioning round holes are formed in the sliding notch, the fixing support comprises a first fixing base plate and a second fixing base plate, the first fixing base plate is horizontally arranged, a driving cylinder is arranged on the first fixing base plate, a driving shaft rod is arranged at the head of the driving cylinder, a pair of through adjusting notches are formed in the second fixing base plate and are arranged in parallel, the adjusting notches are connected with the positioning round holes through connecting screws, and a guide round hole is formed in the guide seat, the driving shaft rod penetrates through the guide circular hole.
As a preferred embodiment of the invention, a detachable guide cylinder is arranged in the guide round hole, and the guide cylinder is made of stainless steel.
In a preferred embodiment of the present invention, the head of the driving shaft is provided with a conical positioning chuck.
The quick fixing device for crankshaft side punching has the following advantages: during the use, the user directly places the bent axle in the frame, then starts driving cylinder for the location dop of driving shaft pole directly supports the central siphon of bent axle, accomplishes the fixed of bent axle. Then, the drilling machine arranged at the side position can be used for drilling, so that the drilling is fast and convenient. Because the drive shaft lever is restricted in the guide cylinder, lateral displacement can not occur, and the punching is accurate. This quick fixing device that punches of bent axle side position simple structure, the effect is obvious, low cost, the practicality is strong.

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 5, the crankshaft side punching quick fixing device 1 includes a fixing base 2, the fixed base 2 is provided with a detachable fixed bracket 3, the fixed bracket 3 is provided with a detachable guide seat 5, the side wall of the fixed base 2 is provided with a sliding notch 21, four positioning round holes 22 are arranged in the sliding notch 21, the fixing bracket 3 includes a first fixing base plate 31 horizontally disposed and a second fixing base plate 32 longitudinally disposed, the first fixing substrate 31 is provided with a driving cylinder 33, the head of the driving cylinder 33 is provided with a driving shaft 34, the second fixing base plate 32 is provided with a pair of parallel through adjusting notches 321, the adjusting notches 321 are connected with the positioning round holes 22 through connecting screws 7, the guiding seat 5 is provided with a guiding circular hole 51, and the driving shaft 34 penetrates through the guiding circular hole 51.
A detachable guide cylinder 6 is arranged in the guide circular hole 51, and the guide cylinder 6 is made of stainless steel.
The head of the drive shaft 34 is provided with a conical positioning collet 341.
In use, as shown in fig. 1 and 2, a user directly places the crankshaft on the frame, and then activates the driving cylinder 33, so that the positioning chuck 341 of the driving shaft 34 directly abuts against the shaft tube of the crankshaft, thereby completing the fixing of the crankshaft. Then, the drilling machine arranged at the side position can be used for drilling, so that the drilling is fast and convenient. Since the drive shaft 34 is constrained within the guide cylinder 6, no side shifting occurs and the hole is drilled accurately.
This quick fixing device that punches of bent axle side position simple structure, the effect is obvious, low cost, the practicality is strong.
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.
