Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical manufacturing, in particular to a motor base horizontal machining clamp. BACKGROUND

[0002] The motor base mainly needs to process the bottom foot plane, the bottom foot hole, the outlet port plane, the outlet port hole, the lifting ring hole, the grounding hole and the end face hole, and the processing positions are distributed on the outer periphery and the upper and lower end faces of the motor base. At present, one bottom foot milling machine tool, two radial drilling machines and one outlet port milling machine tool are needed to complete the processing of the motor base. Among them, the bottom foot milling machine tool is used to complete the processing of the motor base bottom foot plane and the bottom foot hole. One radial drilling machine is used to complete the processing of the motor base lifting ring hole, grounding hole and front end face hole. The outlet port milling machine tool is used to complete the processing of the outlet port plane. The other radial drilling machine is used to complete the processing of the outlet port hole of the motor base.

[0003] Specifically, the worker needs to fix the motor base on the positioning disc through the bottom foot milling machine tool, control the hydraulic push plate to push the motor base bottom foot flat, manually fix the gantry down pressure cylinder, press the oil cylinder to fix the motor base, and then start the program to complete the milling of the bottom foot and the drilling of the bottom foot hole. The worker needs to use the end face hole drill jig and positioning support to assist in processing through one radial drilling machine, and the drill jig takes the previous bottom foot size as a reference to ensure the position of the end face hole. After adjusting the placement angle of the motor base, the worker controls the radial drilling machine to position the blank surface to complete the processing of the end face and the lifting ring threaded hole. The worker needs to fix the motor base on the workbench through the outlet port milling machine tool, and the outlet port plane is flat. The oil cylinder fixes the motor base, and then the worker manually fixes the gantry down pressure cylinder. The oil cylinder is pressed to fix the motor base, and then the program is started to complete the milling of the outlet port plane. The worker needs to use the outlet port drill jig and positioning support to assist in processing through the other radial drilling machine, and the milling of the outlet port is taken as a reference to process the threaded hole of the outlet port.

[0004] It can be seen that the processing sequence of the motor base is the bottom foot milling machine tool, one radial drilling machine, the outlet port milling machine tool and the other radial drilling machine, that is, a special worker is needed to circulate the motor base on the above four devices to realize the processing of different positions. Moreover, the worker's work intensity is relatively large. SUMMARY

[0038] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0039] In a first aspect, one embodiment of the present application provides a motor frame lying clamp.

[0040] Referring to Figures 1-3 The motor frame lying clamp comprises a double-stroke oil cylinder 20, a synchronous angular orientation mechanism, a movable pressing plate 11 arranged on a movable end plate 21 of the double-stroke oil cylinder 20, and a plurality of frame centering blocks 30 distributed on the outer periphery of the double-stroke oil cylinder 20.

[0041] The movable end plate 21 of the double-stroke oil cylinder 20 can move up and down to adapt to motor frames 50 of different heights, and the movable end plate 21 drives the movable pressing plate 11 to move up and down when the movable end plate 21 moves up and down.

[0042] The synchronous angular orientation mechanism is used to simultaneously tighten two bottom feet 51 of the motor frame 50 after the motor frame 50 is fixed to the outer periphery of the double-stroke oil cylinder 20.

[0043] Each frame centering block 30 has at least two layers of stepped structures, the sidewalls of the stepped structures are arc-shaped, and the outer walls of the stepped structures of different layers are adapted to different inner diameters of the stop openings, so that the frame centering block 30 can fix motor frames 50 of different inner diameters of the stop openings.

[0044] After the motor frame 50 is fixed to the outer periphery of the double-stroke oil cylinder 20, the inner diameter of the stop opening of the motor frame 50 is adapted to one layer of stepped structures of the frame centering block 30, the movable end plate 21 of the double-stroke oil cylinder 20 moves downward until the movable pressing plate 11 on the movable end plate 21 presses the upper end surface of the motor frame 50, and the two bottom feet 51 of the motor frame 50 are simultaneously tightened by the synchronous angular orientation mechanism.

[0045] It can be understood that the motor frame 50 is a shell, the shell is hollow inside, and the shell is provided with bottom feet 51, and a hole structure is formed on the bottom feet 51, which is a bottom foot hole. Since the motor frame 50 is a hollow shell, it can be sleeved on the outer periphery of the double-stroke oil cylinder 20.

[0046] It can be understood that the double stroke oil cylinder 20 is a lifting oil cylinder, and the lower end surface of the double stroke oil cylinder 20 remains stationary while the upper end surface of the double stroke oil cylinder 20 moves up and down, so the upper end surface of the double stroke oil cylinder 20 is called the movable end plate 21. Because the heights of different models of motor bases 50 are different, the double stroke oil cylinder 20 is used in the embodiment of the application, so that the double stroke oil cylinder 20 can be adjusted up and down according to the height of the motor, and the motor base 50 of different heights can be fixed and clamped.

[0047] It can be understood that in order to realize the fixation of the inside of the motor base 50 and ensure the stability during the machining of the motor base 50, the base centering block 30 is used in the embodiment of the application. The base centering block 30 can be uniformly distributed on the outer periphery of the double stroke oil cylinder 20, for example, 6-8 base centering blocks 30 can be arranged, and each base centering block 30 surrounds the double stroke oil cylinder. When the motor base 50 is sleeved on the outer periphery of the double stroke oil cylinder 20, the stop opening of the motor base 50 is just sleeved on the side wall of each base centering block 30, so as to realize the internal fixation of the motor base 50.

[0048] Further, because different models of motor bases 50 have different stop opening inner diameters, in order to realize the internal fixation of different models of motor bases 50, the base centering block 30 in the embodiment of the application has at least two layers of stepped structures, and one layer of stepped structure corresponds to one stop opening inner diameter, that is, at least two layers of stepped structures correspond to at least two stop opening inner diameters, so as to realize the fixation of the motor base 50 with different stop opening inner diameters. In order to adapt to the stop opening of the motor base 50, the side wall of the stepped structure is arranged in an arc shape, and the side wall of the same layer of stepped structure of each base centering block 30 forms a cylindrical shape, which is just adapted to the stop opening inner diameter of one model of motor base 50.

[0049] It can be seen that the base centering block 30 in the embodiment of the application is arranged based on the stop opening inner diameter of the motor base 50, and when the foot of the motor base is machined, the height size of the foot and the parallelism size of the foot and the stop opening can be ensured to meet the requirements. Here, a plurality of uniformly distributed base centering blocks 30 are used, rather than a whole ring-shaped centering structure, so that it is convenient to remove iron chips, cutting fluid, etc. during machining. Each base centering block 30 includes at least two layers of stepped structures, for example, two layers of stepped structures are arranged, the side wall of one layer of stepped structure is adapted to the stop opening inner diameter of the motor base 50 of model 315, and the side wall of the other layer of stepped structure is adapted to the stop opening inner diameter of the motor base 50 of model 355. In this way, the clamp can satisfy the fixation and clamping of two models of motor bases 50.

[0050] It can be understood that the synchronous angle orientation mechanism is also arranged outside the double-stroke oil cylinder 20, and is located outside the motor base 50 after the motor base 50 is sleeved on the outer periphery of the double-stroke oil cylinder 20. After the worker fixes the motor base 50 to the outer periphery of the double-stroke oil cylinder 20, the two feet 51 of the motor base 50 can be simultaneously clamped by the synchronous angle orientation mechanism, so that the external fixation of the motor base 50 is realized.

[0051] Before the motor base 50 is fixed to the outer periphery of the double-stroke oil cylinder 20, the stroke of the double-stroke oil cylinder 20 is the largest, and after the worker sleeves the motor base 50 on the outer periphery of the double-stroke oil cylinder 20, the inner diameter of the motor base 50 is matched with the stepped structure of the base centering block 30. At this time, the worker lowers the double-stroke oil cylinder 20, that is, the movable end plate 21 of the double-stroke oil cylinder 20 moves downward until the movable pressing plate 11 on the movable end plate 21 presses the upper end surface of the motor base 50, and at this time, the worker simultaneously clamps the two feet 51 of the motor base 50 through the synchronous angle orientation mechanism. Through the above operation, the fixation and clamping of the motor base 50 are realized, and after that, the upper and lower end surfaces, various hole structures and the like on the motor base 50 can be machined, so that the worker does not need to transfer the motor base 50 between multiple machining devices, and the labor intensity of the worker is reduced.

[0052] In one embodiment, the movable pressing plate 11 in the embodiment of the present application can include a sliding groove and a retractable pressing plate capable of moving along the sliding groove, so that the movable pressing plate 11 has a retracted state and a stretched state.

[0053] Before the motor base 50 is placed on the outer periphery of the double-stroke oil cylinder 20, the movable pressing plate 11 is in the retracted state, so that the movable pressing plate 11 does not touch the inner wall of the motor base 50 during the process of placing the motor base 50 on the outer periphery of the double-stroke oil cylinder 20; after the motor base 50 is fixed to the outer periphery of the double-stroke oil cylinder 20, the movable pressing plate 11 is in the stretched state, so that the movable pressing plate 11 can contact the upper end surface of the motor base 50.

[0054] That is, the movable pressing plate 11 has two states, when the motor frame 50 needs to be sleeved on the outer periphery of the double-acting oil cylinder 20, the movable pressing plate 11 is in a retracted state, so that when the worker sleeves the motor frame 50 on the outer periphery of the double-acting oil cylinder 20, the inner wall of the motor frame 50 will not be contacted by the movable pressing plate 11, so as not to damage the inner wall of the motor frame 50. After the worker sleeves the motor frame 50 on the outer periphery of the double-acting oil cylinder 20, the movable pressing plate 11 is adjusted to a stretched state. Then lower the double-acting oil cylinder 20, at this time the movable end plate 21 is lowered, and the movable pressing plate 11 also follows the lowering, when it is lowered to a height corresponding to the motor frame 50, the movable pressing plate 11 contacts the upper end surface of the motor frame 50, after the upper end surface of the motor frame 50 is pressed tightly, stop lowering the double-acting oil cylinder 20.

[0055] Further, the movable pressing plate 11 can further include a protection block arranged at the end of the telescopic pressing plate, the protection block is used to protect the upper end surface of the motor frame 50 when the movable pressing plate 11 presses the upper end surface of the motor frame 50.

[0056] That is, because the protection block is arranged at the end of the telescopic pressing plate, the telescopic pressing plate and the upper end surface of the motor frame 50 are contacted through the protection block, so that the protection block can protect the upper end surface of the motor frame 50 to a certain extent, avoiding the upper end surface of the motor frame 50 being pressed and damaged.

[0057] Among them, the protection block has many optional ways, for example, a copper block.

[0058] At the beginning, the double-acting oil cylinder 20 is at the highest height, after the motor frame 50 is sleeved into the double-acting oil cylinder 20, the telescopic pressing plate is slid out along the sliding groove and enters the stretched state. After the double-acting oil cylinder 20 is lowered, the protection block of the telescopic pressing plate presses the upper end surface of the motor frame 50, preventing the upper end surface from being pressed and injured. In addition, the position of the telescopic pressing plate needs to avoid the threaded hole position of the upper end surface of the motor frame 50.

[0059] In one embodiment, the clamp provided by the embodiment of the present application can further include:

[0060] A plurality of guide blocks 12 uniformly arranged on the movable end plate 21, the guide blocks 12 are used to guide the movement of the motor frame 50 during the process of placing the motor frame 50 from top to bottom on the outer periphery of the double-acting oil cylinder 20.

[0061] For example, three uniformly distributed guide blocks 12 are arranged on the movable end plate 21, during the process of sleeving the motor frame 50 from top to bottom on the outer periphery of the double-acting oil cylinder 20, the three guide blocks 12 play a guiding role in the movement of the motor frame 50, so that the motor frame 50 can be smoothly sleeved on the outer periphery of the double-acting oil cylinder 20.

[0062] In one embodiment, the synchronous angular orientation mechanism in the embodiment of the present applicationapplicationinclude a first motor 42, a lead screw, a lead screw nut 43 and a positioning block 41, wherein:

[0063] The lead screw is in transmission connection with the first motor 42, and the lead screwapplicationinclude a toothed section and an anti-toothed section;

[0064] The lead screw nut 43applicationinclude a toothed nut and an anti-toothed nut, the toothed nut is arranged on the toothed section of the lead screw, and the anti-toothed nut is arranged on the anti-toothed section of the lead screw;

[0065] The positioning block 41applicationinclude a first positioning block fixedly connected with the toothed nut and a second positioning block fixedly connected with the anti-toothed nut;

[0066] Wherein, the first motor 42 rotates to control the first positioning block and the second positioning block to move towards each other or in opposite directions at the same distance at the same time.

[0067] It can be understood that the first motor 42 rotates to drive the lead screw to rotate, since the lead screw can drive the lead screw nut 43 to move along the lead screw, since one section of the lead screw is a toothed section, the lead screw nut 43 arranged on the toothed section is a toothed nut, and the other section of the lead screw is an anti-toothed section, the lead screw nut 43 arranged on the anti-toothed section is an anti-toothed nut, therefore, the movement directions of the two lead screw nuts 43 are opposite when the lead screw rotates, thus the opposite movement or reverse movement of the two lead screw nuts 43 can be realized by controlling the rotation direction of the first motor 42, thereby realizing the opposite movement or reverse movement of the two positioning blocks 41, so that the two positioning blocks 41 simultaneously and at the same distance tighten the two feet 51 of the motor base 50, or simultaneously and at the same distance expand the distance between the two centering blocks, thereby releasing the two feet 51 that are tightened.

[0068] In the embodiment of the present application, a synchronous angular orientation mechanism is designed, which synchronously clamps the side edges of the base feet 51 of the machine base, so that the base feet 51 of the motor base 50 are symmetrical on the workbench, ensuring that the machining allowances of the two base feet 51 during the milling of the base feet 51 of the motor base 50 are the same, and the distance between the worker and the two base feet 51 is the same. Moreover, the clamping strength of the base feet 51 can be enhanced.

[0069] In actual scenarios, the hydraulic oil circuit at the bottom of the machine tool controls the rotation of the first motor 42, the first motor 42 drives the lead screw to rotate, the lead screw has a toothed section and an anti-toothed section, one side is a toothed section, and the other side is an anti-toothed section, a toothed nut is installed on the toothed section, and an anti-toothed nut is installed on the anti-toothed section, two positioning blocks 41 are respectively connected with a lead screw nut 43, and the first motor 42 can control the two positioning blocks 41 to move towards each other and away from each other at the same distance at the same time when the first motor 42 rotates in opposite directions.

[0070] In one embodiment, the clamp provided by the embodiment of the present application further comprises:

[0071] A rotating base plate, on which the double-stroke oil cylinder 20, the base centering block 30 and the synchronous angular orientation mechanism are arranged, and which can realize 360° horizontal rotation.

[0072] In the process of machining the motor base 50, two end faces and various hole structures of the motor base 50 need to be machined. In order to facilitate machining, the double-stroke oil cylinder 20, the base centering block 30 and the synchronous angular orientation mechanism are arranged on a rotating base plate, so as to realize 360° horizontal rotation of the motor base 50 and facilitate machining operation of workers.

[0073] In one embodiment, the clamp provided by the embodiment of the present application further comprises:

[0074] An angular head device is installed above the double-stroke oil cylinder 20 and is used for machining the hole structure required by the upper end face of the motor base 50.

[0075] That is, the angular head device is arranged above the double-stroke oil cylinder 20. After the motor base 50 is fixed on the outer periphery of the double-stroke oil cylinder 20, a worker can realize machining of the upper end face of the motor base 50, especially machining of the threaded hole of the upper end face, by operating the angular head device.

[0076] Further, the angular head device can specifically comprise a second motor, a main shaft horizontally installed in transmission connection with the second motor, a bevel gear in transmission connection with the main shaft, a 90° angular head in transmission connection with the bevel gear, and a spraying water pipe arranged above the 90° angular head; wherein the 90° angular head is used for machining the hole structure by a drill bit in the vertical direction, and the spraying water pipe is used for flushing the drill bit of the 90° angular head and the hole structure by cutting fluid.

[0077] The bevel gear is also called bevel gear or bevel gear, which is used for transmission between intersecting shafts. Compared with the cylindrical gear, the bevel gear can change the transmission direction.

[0078] It can be understood that rotation of the second motor can drive rotation of the main shaft, and the main shaft drives transmission of the bevel gear, so as to ensure the rotation speed and torque of drilling and tapping. The bevel gear drives rotation of the drill bit on the 90° angular head, so as to drill the upper end face of the motor base 50.

[0079] The bevel gear needs grease lubrication inside and cannot have cutting fluid on the surface.

[0080] Among them, the spray pipe specially cooling 90-degree angle head is designed on the main shaft, the spray pipe is controlled by the machine tool to spray the drill bit and tap, and the iron filings on the surface of the thread hole are washed.

[0081] Among them, the cutting fluid is an industrial liquid used in metal cutting and grinding process to cool and lubricate the tool and workpiece, and the cutting fluid is formed by scientific compounding of various super strong functional additives, and has good cooling performance, lubricating performance, rust prevention performance, oil removal and cleaning function, corrosion prevention function and easy dilution characteristics.

[0082] In one embodiment, the double-stroke oil cylinder 20 includes a telescopic support rod, and the movable end plate 21 of the double-stroke oil cylinder 20 is arranged on the telescopic support rod, and the telescopic support rod is used to drive the movable end plate 21 to move up and down during telescoping.

[0083] That is, the telescopic support rod in the double-stroke oil cylinder 20 can be telescoped to drive the movable end plate 21 to rise and fall.

[0084] Because the motor base 50 has multiple size processes such as a lifting eye hole, a wire outlet, a grounding hole and the like on the outer periphery, and has multiple models, the wire outlet positions of different models of the motor base 50 are different, and meanwhile, the upper and lower of the motor base 50 need to be convenient, the double-stroke oil cylinder 20 is designed. For example, the height difference between the model 315 and the model 355 of the motor base 50 is large, and the difference can reach 400 mm, so a large-diameter double-stroke hydraulic cylinder with a cylinder diameter of 100 mm can be designed, and four telescopic support rods are configured, and the height of the double-stroke oil cylinder 20 can be lifted from 700 mm to 1100 mm through the four telescopic support rods, so that even the motor base 50 with a height of 960 mm can meet the use requirement.

[0085] It can be seen that the motor base 50 is fixed internally by the base centering block 30 in the clamp provided in the embodiment of the present application, and the base centering block 30 includes a multi-layer stepped structure, so that the motor base 50 with different stop opening diameters can be adapted. The two bottom feet 51 of the motor base 50 are synchronously clamped by the synchronous angular orientation mechanism in the clamp provided in the embodiment of the present application. The double-stroke oil cylinder 20 is used to adapt the motor base 50 with different heights in the clamp provided in the embodiment of the present application, and then the upper end surface of the motor base 50 is pressed by the movable pressing plate 11. It can be seen that the clamp provided in the embodiment of the present application can realize the fixing and clamping of multiple models of the motor base 50. After the motor base 50 is fixed and clamped, the bottom foot plane, the bottom foot hole, the wire outlet plane, the wire outlet hole, the lifting eye hole, the grounding hole and the end surface hole of the motor base 50 can be machined by external machining equipment.

[0086] It can be seen that the fixture provided by the embodiment of the present application is a machining center device, which realizes the clamping of the motor base 50 through a certain structure, and is provided with corresponding tools, so as to realize the machining of the end face and the hole structure.

[0087] In the actual scene, before the motor base 50 is clamped, there is a preliminary process, which is completed by a worker, and the motor base 50 is transferred between different machining devices to realize the machining of the end face and the plurality of hole structures, which also needs to be completed by a worker, so that two workers are generally needed to realize the machining of the motor base 50 in the prior art, and the labor intensity of the workers is very large when the motor base 50 is transferred between the plurality of machining devices. If the fixture provided by the embodiment of the present application is used to clamp the motor base 50, the preliminary process and the machining of the end face and the plurality of hole structures can be completed by the same worker, so that the fixture provided by the embodiment of the present application can reduce the number of workers needed, and since the motor base 50 does not need to be transferred between the plurality of machining devices, the labor intensity of the workers can also be reduced.

[0088] If the fixture provided by the embodiment of the present application is used to clamp the motor base 50, the motor base 50 is avoided from being transferred between a plurality of devices, and the machining can be continuously performed on the fixture, so that the machining efficiency can be improved.
