Fixture identification mechanism
Technical field
The present invention relates to a kind of identification mechanisms, and in particular to a kind of fixture identification mechanism.
Background technique
Fixture is to be used to fix processing object during machine-building, is allowed to occupy correct position, with receive construction or
The device of detection, also known as fixture.In a broad sense, any process in technical process, for rapidly, easily and safely pacifying
The device for filling workpiece, all can be described as fixture.When processing the workpiece, the surface to enable workpiece reaches size as defined in drawing, several
What shape and with the technical requirements such as the mutual position accuracy of other surfaces, workpiece must be installed before processing and position and utilize
Fixture is clipped.
But, on the one hand, since the type of workpiece is varied, the type of fixture be also it is ever-changing, process different
Workpiece must use different fixtures, and some clamp-shapeds and structure are all quite similar, these fixtures are installed in workbench
On when being processed, operator may not be able to distinguish well used in fixture it is whether correct, cannot will if mistake
Required workpieces processing clamps, it is necessary to be replaced, bring certain influence to subsequent processing in this way, greatly reduce entirety
Processing efficiency, while using mistake fixture be clamped, processing when, also easily cause the damage of workpiece.Therefore, In
It is extremely important to the identification of fixture during workpieces processing, it is related to the matching of workpiece to be machined and processing program.
On the other hand, multistation, multiple clip rotary table machining center are the development trend of machine tooling equipment, fixture
The increase of quantity necessarily leads to the confusion of program management and complexity, to increase maintenance cost and reduce production efficiency.Existing skill
In art, also operator to be leaned on to identify that process is cumbersome by rule of thumb mostly, expend the time, be easy error, and then fixture occurs and touches
It hits and equipment breakdown.
In view of the above-mentioned problems, Chinese invention patent CN102156861A discloses a kind of " clamp model recognition device ", In
Position sensor is arranged in the bottom of workbench, is connected with flash lamp on position sensor.After fixture is placed on the table, if
The marginal portion of fixture touches the corresponding position on workbench, and corresponding position sensor transmits a signal to flash lamp,
Clamp-shaped is identified according to the flashing of the flash lamp of various combination, and is compared with the database in computer, quickly
Identify the model of fixture.But the device identifies fixture model by using contact position sensor, long-time service is easily made
At the abrasion of position sensor, service life is not only influenced, also easily causes induction insensitive.
Summary of the invention
The technical problem to be solved by the invention for the present situation of prior art is to provide a kind of high sensitivities, use the longevity
Order long fixture identification mechanism.
The technical scheme of the invention to solve the technical problem is: a kind of fixture identification mechanism, including revolution work
Make platform and pedestal, rotary table can be rotated relative to pedestal;Rotary table different location is equipped with multiple fixtures, and turns round work
Make platform equipped at least two detection blocks and detection block can be driven to rotate together, pedestal is equipped at least two close to switch, institute
It states and is connected with warning light close on switch;Detection block can be relative to close to switch rotary, to select under rotary table drive
The control of selecting property is close to be switched on-off, and then by the warning light with close switch connection to identify fixture.
As a further improvement, the fixture identification mechanism further include the valve body being mounted on the rotary table and
The spool being mounted on the base, the valve body are located at the radial outside of the spool, and can opposite Spool rotating;The inspection
Block is surveyed to be installed on valve body, it is described to be located at spool end close to switch;Valve body is rotated with rotary table, so that described
Detection block and close switch movement for the relative rotation.
It improving again, the fixture identification mechanism further includes the bracket positioned at spool end, for installing close to switch, so that
It is located on spool close to switch is firm, is slid to prevent approaching switch by the shock effect that rotary table rotates.
It improves again, the spool end is additionally provided with port plate, and bracket is installed on port plate, further guarantees close open
What is closed is firm.
Compared with prior art, advantages of the present invention: detection block rotation is driven by rotary table, machinery is not needed and connects
Any pressure is touched or applies, the control that detection block can be selective in rotary course is close to be switched on-off, and makes to open with close
It closes connected warning light to light or extinguish, fixture, long service life, high sensitivity is identified with this.

Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
It as shown in figures 1 to 6, is the preferred embodiment of the present invention.
Fixture identification mechanism includes rotary table 1, pedestal 4, detection block 2 and close switch 3.It is connected on close to switch 3
There is warning light, rotary table 1 can be rotated relative to pedestal 4, and 1 different location of rotary table is equipped with multiple fixtures.
Spool 41 is installed on pedestal 4,41 end of spool is equipped with port plate 43, is equipped with bracket 42 on the port plate 43,
It is installed on the bracket 42 close to switch 3.
Valve body 11 is installed, valve body 11 is located at the radial outside of spool 41, and can the opposite rotation of spool 41 on rotary table 1
Turn.Detection block 2 is installed on the different location of valve body 11, and in the preferred embodiment, detection block 2 is installed in the four of valve body 11
On a position, wherein position a does not have detection block 2, and position b detection block 2 is installed to the left, and position c detection block 2 is mounted on its right side
Side, position d detection block 2 are mounted on its left and right sides simultaneously.
Valve body 11 is rotated with rotary table 1, to drive detection block 2 to rotate, when detection block 2 is in close to switch 3
Induction zone when close to the conducting of switch 3, warning light connected to it lights.It in the present embodiment, can there are two close switches 3
Fixture is identified according to the different warning light combinations lighted.
The present embodiment identifies that fixture is realized in the following way according to the different warning light combinations lighted: valve body
11 rotate with rotary table 1, and detection block 2 is driven to rotate, and in state A, two warning lights close to switch 3 are not lighted,
Corresponding tong marks are 1# fixture at this time;In state B, two warning lights close to switch 3 are lighted, at this time corresponding folder
Tool is labeled as 2# fixture;Warning light on the left of in state C close to switch 3 lights, and the warning light of right side close to switch 3 is not bright
It rises, corresponding tong marks are 3# fixture at this time;Warning light on the left of in state D close to switch 3 does not light, and right side is close to open
The warning light of pass 3 lights, and corresponding tong marks are 4# fixture at this time.When identifying different fixtures in this way, various combination is had
Warning light light, operator can identify fixture according to the prompt of warning light.
