Description

Coplanar platform protector

Technical Field

The utility model relates to a protector, concretely relates to coplane platform protector.

Background

Air supporting precision motion platform belongs to precision instruments, need carry out the precision protection in order to prolong its life and guarantee to remove the precision of in-process, but because in the air supporting precision motion platform working process, the workstation need be in X to removing with Y, prior art mainly adopts flexible protection casing to carry out the protection of singleton to single shafting (X axle or Y axle), is difficult to accomplish totally closed protection, also is difficult to accomplish omnidirectional dustproof, waterproof, prevent the foreign matter, and the protecting effect is not good.

SUMMERY OF THE UTILITY MODEL

The utility model provides a coplane platform protector, adopt the protection of full closed, can improve the protecting effect under the prerequisite that does not influence platform work to the not enough of prior art.

In order to realize the technical scheme, the utility model provides a coplane platform protector, include: a base platform, two parallel Y-direction guide rails arranged at intervals are arranged on the base platform, an X-direction guide rail is arranged on the two Y-direction guide rails, a workbench is arranged on the X-direction guide rail, supporting seats are arranged on four end corners of the base station, two guide rods are fixed on the supporting seats in parallel along the Y direction, a Y-direction roller is arranged on each guide rod, an air bearing is embedded in the Y-direction roller, the two ends of the Y-direction roller are provided with dustproof gaskets which are sleeved on the guide rod and are attached to the end surface of the Y-direction roller, the middle part of the protection plate is provided with a butt joint hole which is matched with the workbench, the protection plate is fixedly connected with the workbench through the butt joint hole, the left end and the right end of the protection plate are respectively lapped on the left Y-direction roller and the right Y-direction roller, the outer cover is fixed on the side edge of the base station, and the mounted position of dustcoat is higher than the guard plate, reserves the work gap between dustcoat and the guard plate, Y is provided with the side guard plate to the lateral surface bottom of gyro wheel.

In the above technical solution, during specific work, the table is driven by the X-direction guide rail or the Y-direction guide rail motor to move the position. When the workstation moved in Y to, Y lets in gas to the inboard air bearing of gyro wheel for form one deck air film between air bearing and the guide bar, the workstation drives the guard plate and removes under the drive of Y to guide rail motor, and the guard plate then drives Y to the gyro wheel, because the effort relation of air film, can realize that Y slides to the Y of gyro wheel at the guide bar to no friction, the guard plate follows the workstation and upwards synchronous motion at Y, thereby reaches the protection of coplane platform Y direction. When the workbench moves in the X direction, the action force of the workbench drives the protection plate, the protection plate drives the Y-direction roller to roll, and the protection plate moves upwards in the X direction along with the workbench, so that the protection in the X direction of the coplanar platform is achieved. In the gas action process, the Y-direction roller is provided with the dustproof gaskets at the two ends, so that no dust exists on the guide rod, and the abnormal condition caused by the sliding of the roller due to the dust is avoided to the maximum extent.

Preferably, the butt joint hole that the guard plate intermediate position set up passes through the bolt and is connected with the periphery of workstation, and airtight rubber ring is installed with workstation butt joint department to the butt joint hole, can prevent that the butt joint department of butt joint hole and workstation from falling into the dust.

Preferably, install dustproof brush on the interior limit of dustcoat and guard plate reservation gap department, there is the dust in work area on the guard plate, because the effect of the dustproof brush of dustcoat and guard plate combination department can concentrate on dustcoat breach department with the dust, convenient clearance.

Preferably, the side guard plate passes through the bolt fastening on the base station side, and the side guard plate slope sets up, side guard plate top is tangent with the bottom of Y to the gyro wheel, prevents that the dust from side entering Y to the gyro wheel.

The utility model provides a pair of coplane platform protector's beneficial effect lies in: this coplane platform protector simple structure, design benefit through institutional advancement for guard plate and workstation are in X to with Y to synchronous motion, can realize guard plate and whole device at X to with the ascending coplane protection of Y, form the protection of full closed formula, can protect precision devices such as internal motor to expose in the external world, reduce the damage of different degree, and then can improve the protecting effect under the prerequisite that does not influence platform work.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art without any inventive step are within the scope of the present invention.

Example (b): a coplanar platform guard.

Referring to fig. 1 to 5, a coplanar platform guard includes: the device comprises a base platform 2, two Y-direction guide rails 8 arranged in parallel at intervals are arranged on the base platform 2, X-direction guide rails 10 are arranged on the two Y-direction guide rails 8, a workbench 1 is arranged on the X-direction guide rails 10, the X-direction guide rails 10 and the Y-direction guide rails 8 are used for driving the workbench 1 to move in the X direction and the Y direction, supporting seats 9 are arranged at four end corners of the base platform 2, two guide rods 5 are fixed on the supporting seats 9 in the Y direction in parallel, a Y-direction roller 7 is arranged on each guide rod 5, an air bearing 12 is embedded in the Y-direction roller 7, the air bearing 12 is matched with the Y-direction roller 7 to form a clearance fit state, when the device works, air is introduced into the air bearing 12, so that an air film is formed between the air bearing 12 and the guide rods 5, the friction of the Y-direction roller 7 in the Y direction during movement is reduced, dustproof gaskets 6 are arranged at two ends of the Y-direction roller 7, the dustproof gaskets 6 are, in the gas action process, the dust-proof gaskets 6 are arranged at the two ends of the Y-direction roller 7, so that no dust exists on the guide rod 5, and the abnormal sliding of the Y-direction roller 7 caused by the dust is avoided to the maximum extent; the middle part of the protection plate 3 is provided with a butt joint hole which is matched with the workbench 1, the butt joint hole arranged at the middle position of the protection plate 3 is connected with the periphery of the workbench 1 through bolts, a closed rubber ring is arranged at the butt joint part of the butt joint hole and the workbench 1, dust can be prevented from falling into the butt joint part of the butt joint hole and the workbench, the left end and the right end of the protection plate 3 are respectively overlapped on a left roller 7 and a right roller 7 in the Y direction, the outer cover 4 is fixed on the side edge of the base station 2, the installation position of the outer cover 4 is higher than that of the protection plate 3, a working gap is reserved between the outer cover 4 and the protection plate 3, namely, the protection plate 3 can pass below the outer cover 4 in the moving process, a dustproof brush is arranged on the inner edge of the reserved gap between the outer cover 4 and the protection plate 3, when dust exists in a working area on the protection plate 3, the, convenient clearance, Y is provided with side guard plate 11 to the lateral surface bottom of gyro wheel 7, side guard plate 11 passes through the bolt fastening on 2 sides of base station, and side guard plate 11 slope sets up, 11 tops of side guard plate are tangent to the bottom of gyro wheel 7 with Y, prevent that the dust from side entering Y to gyro wheel 7.
