Description

Technical Field

[0001] The utility model relates to the technical field of equipment for moving a shaft sleeve during shaft sleeve turning, in particular to a shaft sleeve turning loading and unloading device. Background Art

[0002] Before turning the pin, the sleeve needs to be placed on the fixed terminal of the lathe. After the pin is removed, the sleeve needs to be removed from the fixed terminal of the lathe. The existing moving mechanism generally uses a grasping device to grasp the outer wall of the sleeve to hold the sleeve stably. This grasping operation requires the grasping device to provide a large grasping force to maintain it, and the grasping device and the sleeve are generally in rigid contact. Therefore, under a large clamping force and rigid contact state, it is easy to cause damage to the outer wall of the sleeve. Therefore, in the prior art, elastic material is often set on the side where the grasping device contacts the sleeve to reduce rigid contact damage. However, simply setting rigid contact material cannot overcome the problem of damage caused by excessive clamping force. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing sleeve loading and unloading device clamps and moves the outer wall of the sleeve, but the clamping force is too large, which may cause damage to the outer wall of the sleeve. In view of the above-mentioned defects of the prior art,

[0004] A shaft sleeve turning loading and unloading device is provided.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A sleeve turning loading and unloading device is constructed. The device is arranged at the front end of a manipulator for picking up and placing the sleeve, and includes a mounting seat, on which a cylindrical picking and placing arm is fixedly connected. The device also includes a plurality of air bags evenly distributed along the circumferential direction of the picking and placing arm, and a vacuum pump is also arranged on the mounting seat. The vacuum pump is used to inflate or evacuate the air bag. When picking up and placing the sleeve, the picking and placing arm is inserted into the sleeve under the control of the manipulator, and the air bag is inflated by the vacuum pump so that the sleeve is firmly mounted on the air bag. After the manipulator moves the sleeve to a predetermined position, the vacuum pump is used to suck the air bag flat so that the picking and placing arm can be withdrawn from the sleeve.

[0007] In the above scheme, the airbag is inflated by an air pump to make the airbag expand inside the sleeve. After the expanded airbag contacts the inner wall of the sleeve, it continues to be slightly inflated and expanded, so that the sleeve is firmly mounted on the expanded airbag. Therefore, the contact between the sleeve and the device during the entire grasping process in this scheme is completely flexible, and the contact process can completely avoid the problem of sleeve damage caused by rigid contact. At the same time, this technical solution fixes the sleeve on the device by means of airbag expansion, which can effectively avoid the problem of sleeve damage caused by excessive clamping force.

[0008] Preferably, a plurality of airbag mounting grooves are provided on the side wall of the pick-and-place arm, the plurality of airbag mounting grooves are evenly distributed around the circumferential direction of the pick-and-place arm, and the length direction of the airbag mounting grooves is parallel to the axial direction of the pick-and-place arm, and a plurality of threaded holes and a tributary airway are provided at the bottom of the airbag mounting grooves for fixing the airbags; a main airway is provided at the axis of the pick-and-place arm, the tributary airway is arranged along the radial direction of the pick-and-place arm, and the main airway is connected to the tributary airway.

[0010] Preferably, a connecting pipe is provided on the mounting seat, the connecting pipe is communicated with the main airway, and the connecting pipe is connected to a dual-purpose pump for suction and inflation.

[0011] The connecting tube, main airway, bronchial airway and inflation nozzle in the above scheme form a connected airflow channel to facilitate inflating and deflating the airbag.

[0012] Preferably, the airbag is in the shape of an elongated strip and includes a mounting surface and an expansion surface, wherein the mounting surface is fixed to the bottom of the airbag mounting groove by bolts; when the airbag is inflated, most of the expansion surface extends outside the airbag mounting groove, so that the diameter of the circle where the expansion surfaces of several airbags are located away from the axis of the pick-and-place arm is increased.

[0013] Preferably, the threaded hole on the mounting surface corresponding to the bottom of the airbag mounting groove and the inflation nozzle are respectively provided with a fixing hole and an inflation port; the mounting surface is fixed to the bottom of the airbag mounting groove by bolts; the inflation nozzle passes through the inflation port so that the end of the inflation nozzle is located inside the airbag.

[0014] Preferably, the airbag mounting surface is a rigid plate-like structure, and the mounting surface matches the bottom of the airbag mounting groove.

[0015] The beneficial effects of the utility model are:

[0016] 1. The utility model provides an airbag installation groove on the pick-and-place arm, and an airbag is arranged in the airbag installation groove. The airbag can be inflated and deflated by a dual-purpose air pump.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0032] In order to facilitate the description and understanding of the position, the top surface of the cylindrical shell is defined as the upper surface, the bottom surface is defined as the lower surface, the axis direction is defined as the vertical direction, and the direction parallel to the top surface or the side surface is defined as the horizontal direction.

[0033] The utility model specifically provides a shaft sleeve turning loading and unloading device, which is mainly used to grab flanges. When in use, the device is arranged at the front end of a manipulator, so that the device can move along with the movement of the manipulator, and then the flange is moved from one position and placed to another position by the manipulator equipped with the device.

[0034] Example 1

[0035] like Figure 1-Figure 5 A preferred embodiment of the utility model is provided, a sleeve turning loading and unloading device, which is arranged at the front end of a manipulator for picking up and placing the sleeve, and includes a mounting seat 100, on which a cylindrical picking and placing arm 200 is fixedly connected, the device also includes three air bags 300 evenly distributed along the circumferential direction of the picking and placing arm 200, and a vacuum pump (the figure shows the vacuum pump) is also arranged on the mounting seat 100, and the vacuum pump is used to inflate or evacuate the air bags 300; when picking up and placing the sleeve, the picking and placing arm 200 is inserted into the sleeve under the control of the manipulator, and the air bag 300 is inflated by the vacuum pump so that the sleeve is firmly mounted on the expanded air bag 300. After the manipulator moves the sleeve to a predetermined position, the vacuum pump is used to suck the air bag 300 flat so that the picking and placing arm 200 can be drawn out of the sleeve.

[0036] In the above scheme, the airbag 300 is inflated by a dual-purpose pump for vacuum and inflation, so that the airbag 300 expands in the sleeve. After the expanded airbag 300 contacts the inner wall of the sleeve, it continues to be slightly inflated and expanded, so that the sleeve is firmly mounted on the expanded airbag 300. Therefore, the contact between the sleeve and the device during the entire grasping process in this scheme is completely flexible, and the contact process can completely avoid the problem of sleeve damage caused by rigid contact. At the same time, this technical solution fixes the sleeve on the device by expanding the airbag 300, which can effectively avoid the problem of sleeve damage caused by excessive clamping force.

[0037] Specifically, three airbag installation grooves 201 are formed on the side wall of the pick-and-place arm 200, and the three airbag installation grooves 201 are evenly distributed around the circumference of the pick-and-place arm 200. The evenly distributed airbag installation grooves 201 allow the airbag 300 disposed in the airbag installation grooves 201 to form three relatively symmetrical fixing surfaces, so that the sleeve can be stably fixed on the pick-and-place arm 200 and the airbag 300. Moreover, the length direction of the airbag installation groove 201 is parallel to the axial direction of the pick-and-place arm 200, so that any position reached by the airbag 300 in the length direction of the pick-and-place arm 200 can be used to fix the sleeve.

[0038] In order to form a connected air flow passage between the air pump and the airbag, the bottom of the airbag mounting groove 201 is provided with a plurality of threaded holes 2011 for fixing the airbag and a tributary 2012, and the tributary 2012 is located in the middle of the bottom of the airbag mounting groove 201, so as to accelerate the expansion speed of the airbag 300 when inflated; a main airway 202 is opened at the axis of the pick-and-place arm 200, and the tributary 2012 is arranged along the radial direction of the pick-and-place arm 200, and the main airway 202 is connected with the tributary 2012, so that after the airflow is diverted at the end of the main airway 202, different airbags 300 are inflated at the same time through different tributaries 2012; similarly, when vacuuming, the airflow inside the airbag 300 passes through different tributaries 2012 and mixes in the main airway 202 to form an airflow for discharge.

[0039] Among them, one end of the bronchial passage 2012 located in the airbag mounting groove 201 is connected with an inflation nozzle 2013 , and the inflation nozzle 2013 is communicated with the bronchial passage 2012 , so that the airflow can enter the inflation nozzle 2013 after passing through the bronchial passage 2012 .

[0040] In order to facilitate the connection of the dual-purpose air pump for suction and inflation with the air flow passage, a connecting pipe 101 is provided on the mounting seat 100 , and the connecting pipe 101 is communicated with the main air channel 202 , and the connecting pipe 101 is connected to the dual-purpose air pump for suction and inflation.

[0041] The connecting tube 101 , the main airway 202 , the bronchial airway 2012 and the inflation nozzle 2013 in the aforementioned solution form a connected airflow passage to facilitate the inflation and deflating of the airbag 300 .

[0042] Among them, the airbag 300 is in the shape of a long strip, and the airbag 300 includes a mounting surface 301 and an expansion surface 302. The mounting surface 301 is fixed to the bottom of the airbag mounting groove 201 by bolts; when the airbag 300 is inflated, most of the expansion surface 302 extends outside the airbag mounting groove 201, so that the diameter of the circle where the expansion surfaces 302 of the three airbags are away from one end of the pick-up and place arm 200 is increased.

[0043] It should be noted that the threaded hole 2011 on the mounting surface 301 corresponding to the bottom of the airbag mounting groove 201 and the inflation nozzle 2013 are respectively provided with a fixing hole 3011 and an inflation port 3012; the mounting surface 301 is fixed to the bottom of the airbag mounting groove 201 by bolts; the inflation nozzle 2013 passes through the inflation port 3012 so that the end of the inflation nozzle 2013 is located inside the airbag 300.

[0044] Furthermore, the mounting surface 301 of the airbag 300 is a rigid plate-shaped structure, and the mounting surface 301 matches the bottom of the airbag mounting groove 201 .

[0045] Example 2

[0046] like Figure 6-Figure 8 As shown, the difference between this embodiment and embodiment 1 lies in the difference in the airbag installation slot and the number of airbags arranged in the airbag installation slot. In this embodiment, the airbag installation slot adopts any integer greater than 3, and the airbag installation slots are evenly distributed on the outer side wall of the pick-and-place arm. For example, when there are four airbag installation slots, as shown in the figure, the angle between two adjacent airbag installation slots is 90°. When the airbag installation slots are at other angles, the angle between two adjacent airbag installation slots is the angle after the circumference is equally divided according to the number of airbag installation slots.

[0047] Example 3

[0048] As a special implementation of the utility model, Figure 9-10As shown, the device is arranged at the front end of the manipulator for picking up and placing the sleeve, and includes a mounting seat 100, on which a cylindrical picking and placing arm 200 is fixedly connected, and an air bag 300 in a cylindrical shape is fixedly mounted on the outer wall of the picking and placing arm 200, the inner wall of the air bag 300 is a mounting surface, and the outer wall and both ends are expansion surfaces, and the outer wall forms a fixed surface for fixing the sleeve; when picking up and placing the sleeve, the picking and placing arm 200 is inserted into the sleeve under the control of the manipulator, and the air bag is inflated by pumping air through a vacuum pump, so that the sleeve is firmly mounted on the air bag 300, and after the manipulator moves the sleeve to a predetermined position, the air bag 300 is sucked flat by the vacuum pump, so that the picking and placing arm can be drawn out of the sleeve.

[0049] Of course, in order to ensure that the pick-and-place arm in any of the above-mentioned embodiments can be inserted into the sleeve, the sum of the diameter of the pick-and-place arm and the diameter when the airbag starts to expand is smaller than the diameter of the sleeve; preferably, the sum of the diameter of the pick-and-place arm and the diameter when the airbag starts to expand is smaller than half of the diameter of the sleeve, so that the pick-and-place arm equipped with the airbag can be easily inserted into the sleeve.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
