Abstract
The invention provides a crankshaft oil hole angular error-proofing positioning device which comprises a connecting rod neck limiting block, a first screw, a flange end supporting block and a second screw, wherein the connecting rod neck limiting block is connected with one end of the flange end supporting block through the first screw, and the second screw is arranged at the other end of the flange end supporting block. The beneficial effects of the invention are as follows: the angular positioning of the workpiece can be realized through the connecting rod neck limiting block, and the angular offset of the workpiece is limited.
Description
Technical Field
The invention relates to a positioning device, in particular to a crank oil hole angular misalignment-preventing positioning device.
Background
The workpiece positioning of the crankshaft oil hole drilling station ensures the rough positioning of the whole workpiece when the workpiece is placed in a machine tool fixture by a manipulator capable of automatically feeding and discharging. For a four-cylinder crankshaft, the workpiece does not have angular offset at the moment of being put into a machine tool; however, for the three-cylinder crankshaft, due to the asymmetric distribution of self gravity, the whole workpiece can possibly generate angular offset at the moment when the manipulator places the workpiece, so that a special angular error proofing device is required to be designed to limit the angular offset of the three-cylinder workpiece at the moment when the three-cylinder workpiece is placed, the first connecting rod detection device or the cutter of the machine tool is prevented from colliding with the workpiece when the machine tool is clamped and the occurrence of accidents is avoided; meanwhile, the pneumatic detection of the first connecting rod neck position of the workpiece by the machine tool after clamping is guaranteed so as to realize coarse positioning of the oil hole angle.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides a crank oil hole angular error-proofing positioning device.
The invention provides a crankshaft oil hole angular error-proofing positioning device which comprises a connecting rod neck limiting block, a first screw, a flange end supporting block and a second screw, wherein the connecting rod neck limiting block is connected with one end of the flange end supporting block through the first screw, and the second screw is arranged at the other end of the flange end supporting block.
As a further improvement of the invention, the flange end supporting block comprises a supporting plate and a connecting plate, wherein the supporting plate is perpendicular to the connecting plate, the first screw is connected with the supporting plate, and the second screw is arranged on the connecting plate.
The beneficial effects of the invention are as follows: through the scheme, the angular positioning of the workpiece can be realized through the connecting rod neck limiting block, and the angular offset of the workpiece is limited.

Detailed Description
The invention is further described with reference to the following description of the drawings and detailed description.
As shown in fig. 1 to 5, the angular error-proofing positioning device for the crankshaft oil hole comprises a connecting rod neck limiting block 1, a first screw 2, a flange end supporting block 3 and a second screw 4, wherein the connecting rod neck limiting block 1 is connected with one end of the flange end supporting block 3 through the first screw 2, the second screw 4 is arranged on the other end of the flange end supporting block 3, and the connecting rod neck limiting block 1 is made of 45# steel.
As shown in fig. 1 to 5, the flange end supporting block 3 includes a supporting plate and a connecting plate, the supporting plate is perpendicular to the connecting plate, the first screw 2 is connected with the supporting plate, and the second screw 4 is disposed on the connecting plate.
As shown in fig. 3 and 4, four-cylinder crankshaft connecting rod necks and balance weights are symmetrically distributed at 180 degrees, when the four-cylinder crankshaft connecting rod necks and the balance weights are placed in a machine tool, the gravity center of a workpiece is on the connecting rod neck connecting line, and the workpiece cannot deviate in an angular direction; the three-cylinder crankshaft connecting rod is distributed at 120 degrees, the balance weights are distributed at 120 degrees, and the angle direction of a workpiece placed in a machine tool is at risk of deviation. According to the angular error-proofing positioning device for the crankshaft oil hole, when a workpiece is placed in a machine tool, the first connecting rod neck faces downwards, and at the moment, the third connecting rod neck is placed in the arc area in the angular positioning block of the supporting device, so that initial angular positioning is performed on the placed workpiece, and meanwhile, angular offset of the workpiece after the workpiece is placed in the machine tool is limited, accurate positioning of the workpiece is ensured, and collision between the internal structure of the machine tool and the workpiece is prevented.
The angular error-proofing positioning device for the crankshaft oil hole has the following advantages:
and I, adding an angular limiting block (namely a connecting rod neck limiting block 1) of a third connecting rod neck on the workpiece positioning clamp to realize the angular positioning of the workpiece and limit the angular offset of the workpiece.
And II, the workpiece is in direct contact with the connecting rod neck limiting block 1, if the angle of the workpiece is not right, the workpiece cannot be placed into a machine tool fixture, the machine tool automatically alarms, the error prevention of equipment hardware is realized, and the risk of cutter collision is eliminated.
And III, connecting the connecting rod neck limiting block 1 with the flange end supporting block 3 of the three-cylinder crankshaft by adopting the first screw 2, wherein the time and the steps of workpiece changing are not increased along with the synchronous changing of the flange end supporting block 3, as shown in figure 1.
IV, the connecting rod neck limiting block 1 is connected with the flange end supporting block 3, so that the design is reasonable, and the connecting rod neck limiting block cannot interfere with a workpiece and a clamp;
v. the connecting rod neck limiting block 1 is made of 45# steel, no special process is needed, and the connecting rod neck limiting block is easy to detach and replace if damaged.
The foregoing is a further detailed description of the invention in connection with the preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the invention, and these should be considered to be within the scope of the invention.
