Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a multi-station turntable machine. Background Art

[0002] In the existing machining field, in order to improve production efficiency, the processing of multiple processes is usually achieved by one device, and the multi-station turntable machine is one of the most widely used ones. The existing multi-station turntable machine generally includes a machine base, a turntable rotatably set on the top of the machine base, and a number of processing units set on the top of the machine base and distributed on the edge of the turntable for performing various processing procedures. The processing unit can be a drilling unit, a deburring unit or a tapping unit (specifically set according to processing requirements). A fixture is fixed on the turntable near the edge. The fixture is designed according to the workpiece to be processed. The workpiece is fixed on the fixture, and then the turntable rotates to make the workpiece pass through each processing unit in turn to complete each processing procedure. Furthermore, some multi-station turntable machines will also set a loading robot and a unloading robot on the top of the machine base to realize automatic loading and unloading.

[0003] During the machining process, coolant is used to cool the tool in order to ensure the tool life. However, for multi-station rotary table machines, since the electrical system must be installed inside the machine base to minimize the overall volume, the usual method is to set the machine base to be well sealed to ensure that the cooling water does not leak in. The coolant will remain on the surface of the machine base and flow out of the machine base as it flows, which will make it difficult to recover the coolant and cause a waste of resources. Utility Model Content

[0004] The utility model aims to solve the above problems existing in the prior art and proposes a multi-station turntable machine to solve the problem that the coolant is difficult to recycle.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A multi-station turntable machine comprises a machine base, a turntable arranged on the top of the machine base, and a plurality of processing units fixedly connected to the top of the machine base and distributed on the edge of the turntable, characterized in that the machine base comprises a frame and a top plate fixed to the top of the frame, the top plate is provided with a plurality of drainage holes, a water receiving bucket located below the top plate is fixedly connected in the frame, a drainage part is fixedly connected to the bottom of the water receiving bucket, the water receiving bucket has a downwardly concave water receiving trough and each drainage hole is located above the water receiving trough, the drainage part has a drainage trough connected to the water receiving trough, a clearance port is provided on the rear side of the frame, the drainage part extends out of the clearance port and the drainage trough passes through the drainage part extending out of the clearance port.

[0007] During processing, the coolant is sprayed to cool the tool of the processing unit. The coolant flows onto the top plate, and then flows from the leaking hole on the top plate into the water receiving trough of the water receiving bucket. Since the bottom of the water receiving bucket is fixedly connected with a drainage part, and the drainage part has a drainage trough connected to the water receiving trough, the coolant flowing into the water receiving trough will flow into the drainage trough of the drainage part. The drainage part extends out of the makeshift port on the rear side of the frame, and the drainage trough runs through the drainage part extending out of the makeshift port, so the coolant flowing into the drainage trough will eventually flow out of the machine base and be recovered. Through the above-mentioned arrangement, on the one hand, the coolant can be conveniently recovered in a centralized manner to reduce the waste of coolant, and on the other hand, it can also avoid the influence of the electrical system arranged in the machine base due to the need to recover the coolant.

[0008] In the above-mentioned multi-station turntable machine, the rear side edge of the bottom wall of the drainage groove is inclined downward relative to the front side edge.

[0009] The rear side edge of the bottom wall of the drainage trough is set to be inclined downward relative to the front side edge. After the coolant falls into the drainage trough from the water receiving trough, it can utilize the slope of the bottom wall of the drainage trough to accelerate the outflow for recovery, and also reduce the residual coolant in the drainage trough.

[0010] In the above-mentioned multi-station turntable machine, the water receiving trough has a plurality of guide walls, each of which is arranged obliquely, and each of which is connected to the left and right sides and the front side of the bottom wall of the drainage trough.

[0011] By setting the guide walls, the coolant flowing into the water receiving trough can flow into the drainage trough more easily, reducing the coolant residue in the water receiving bucket and improving the recovery rate of the coolant.

[0012] In the above-mentioned multi-station turntable machine, the frame includes a cubic frame and a sealing plate fixedly connected to the four sides and the bottom of the cubic frame. A plurality of connecting strips are fixedly connected to the inner side of the upper portion of the cubic frame. The water receiving bucket has a surrounding plate at the notch of the water receiving trough. The upper side of the surrounding plate is welded and fixedly connected to the lower surface of each connecting strip.

[0013] Through the above arrangement, the water receiving bucket can be fixedly connected to the frame body, so that the coolant flowing down from the water leakage hole can be recovered by using the water receiving bucket.

[0014] In the above-mentioned multi-station turntable machine, four water retaining bars are fixedly connected to the top edge of the cubic frame, each water retaining bar forms a square frame, the top plate is located on the inner side of the square frame formed by each water retaining bar and the upper surface of each water retaining bar is higher than the upper surface of the top plate.

[0015] Through the above arrangement, the coolant will be surrounded after falling on the top plate and will not flow out to the surroundings, thereby reducing the waste of coolant, allowing more coolant to be recovered, and also ensuring the cleanliness of the on-site working environment.

[0016] In the above-mentioned multi-station turntable machine, the top plate has a threading hole, and a threading waterproof seat is fixedly connected to the upper end of the threading hole on the upper surface of the top plate, and a sealing ring is provided between the bottom of the threading waterproof seat and the upper surface of the top plate.

[0017] The threading hole is used for electrical threading. By fixing a threading waterproof seat at the upper end opening of the threading hole on the upper surface of the top plate, a sealing ring is arranged between the bottom of the threading waterproof seat and the upper surface of the top plate to prevent coolant from leaking into the frame through the threading hole.

[0018] Compared with the prior art, the multi-station turntable machine is provided with a drainage hole on the top plate and a water receiving bucket with a drainage part fixedly connected to the bottom is provided in the frame body below the top plate. The drainage part extends out of the frame body through the yield opening of the frame body, so that the coolant can flow from the drainage hole to the water receiving groove of the water receiving bucket, and then flow into the drainage groove and finally flow out of the machine base for recovery. Therefore, on the one hand, the coolant can be conveniently recovered in a centralized manner to reduce the waste of coolant, and on the other hand, it can also avoid the influence of the electrical system arranged in the machine base due to the recovery of the coolant.

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1 — Figure 5 As shown, the multi-station turntable machine includes a machine base 1, a turntable 2 arranged on the top of the machine base 1, a loading robot 3, an unloading robot 4 and a plurality of processing units 5 all fixedly connected to the top of the machine base 1, and a protective cover (not shown in the figure) fixedly connected to the top of the machine base 1. The loading robot 3, the unloading robot 4, the processing units 5 and the turntable 2 are all located on the inner side of the protective cover, the loading robot 3, the unloading robot 4 and the plurality of processing units 5 are distributed on the edge of the turntable 2, and a clamp 6 is provided on the turntable 2 near the edge. Specifically, the base 1 includes a frame 1a and a top plate 1b fixed to the top of the frame 1a, the top plate 1b is provided with a plurality of leakage holes 1b1, a water receiving bucket 7 located below the top plate 1b is fixedly connected to the frame 1a, a drainage portion 7b is fixedly connected to the bottom of the water receiving bucket 7, the water receiving bucket 7 has a downwardly recessed water receiving groove 7a and each leakage hole 1b1 is located above the water receiving groove 7a, the drainage portion 7b has a drainage groove 7b1 connected to the water receiving groove 7a, a clearance port is provided on the rear side of the frame 1a, the drainage portion 7b extends out of the clearance port and the drainage groove 7b1 penetrates the drainage portion 7b extending out of the clearance port. The frame 1a includes a cubic frame 1a1 and a sealing plate 1a2 fixedly connected to the four sides and the bottom of the cubic frame 1a1. A plurality of connecting strips 1a3 are fixedly connected to the inner side of the upper portion of the cubic frame 1a1. The water receiving bucket 7 has a surrounding plate 7c at the notch of the water receiving trough 7a. The upper side of the surrounding plate 7c is fixedly connected to the lower surface of each connecting strip 1a3 by welding.

[0027] The loading manipulator 3 clamps the workpiece into the fixture 6 for clamping, and then the turntable 2 rotates to make the workpiece be processed in each processing unit 5 in turn, and finally the unloading manipulator 4 removes the processed workpiece from the fixture 6 and completes the unloading. During the processing, the coolant will spray to cool the tool of the processing unit 5. The coolant flows to the top plate 1b, and then flows from the leaking hole 1b1 on the top plate 1b to the water receiving groove 7a of the water receiving bucket 7. Since the bottom of the water receiving bucket 7 is fixedly connected with the drainage part 7b, and the drainage part 7b has a drainage groove 7b1 connected to the water receiving groove 7a, the coolant flowing into the water receiving groove 7a will flow into the drainage groove 7b1 of the drainage part 7b. The drainage part 7b is extended out of the clearance port on the rear side of the frame 1a, and the drainage groove 7b1 penetrates the drainage part 7b extending out of the clearance port, so the coolant flowing into the drainage groove 7b1 will eventually flow out of the machine base 1 and be recovered. Through the above arrangement, on the one hand, the coolant can be conveniently collected and recovered to reduce the waste of the coolant, and on the other hand, the influence on the electrical system arranged in the machine base 1 caused by the recovery of the coolant can be avoided.

[0028] like Figure 4As shown, in this embodiment, the rear side edge of the bottom wall of the drainage groove 7b1 is tilted downward relative to the front side edge. The rear side edge of the bottom wall of the drainage groove 7b1 is tilted downward relative to the front side edge. After the coolant falls from the water receiving groove 7a into the drainage groove 7b1, it can be accelerated to flow outward for recovery by utilizing the slope of the bottom wall of the drainage groove 7b1, and the coolant residue in the drainage groove 7b1 is also reduced. The water receiving groove 7a has a plurality of guide walls 7a1, each of which is tilted, and each of which is connected to the left and right sides and the front side of the bottom wall of the drainage groove 7b1. Through the arrangement of each guide wall 7a1, the coolant flowing into the water receiving groove 7a can flow into the drainage groove 7b1 more easily, reducing the coolant residue in the water receiving bucket 7, and improving the recovery rate of the coolant.

[0029] Furthermore, if Figure 3 and Figure 5 As shown, four water retaining strips 1a4 are fixedly connected to the top edge of the cubic frame 1a1, and each water retaining strip 1a4 forms a square frame. The top plate 1b is located on the inner side of the square frame formed by each water retaining strip 1a4, and the upper surface of each water retaining strip 1a4 is higher than the upper surface of the top plate 1b. Through the above arrangement, the coolant will be surrounded after falling on the top plate 1b and will not flow out to the surroundings, which reduces the waste of coolant and allows more coolant to be recovered, while also ensuring the cleanliness of the on-site working environment. The top plate 1b has a threading hole, and a threading waterproof seat 8 is fixedly connected to the upper end of the threading hole on the upper surface of the top plate 1b, and a sealing ring is provided between the bottom of the threading waterproof seat 8 and the upper surface of the top plate 1b. The threading hole is used for electrical threading. By fixing the threading waterproof seat 8 at the upper end of the threading hole on the upper surface of the top plate 1b, a sealing ring is set between the bottom of the threading waterproof seat 8 and the upper surface of the top plate 1b to prevent the coolant from leaking into the frame 1a from the threading hole.
