Description

Technical Field

[0001] The utility model relates to the technical field of a clamping structure of a press-fitting machine, in particular to a press-fitting mechanism with a clamping and positioning function. Background Art

[0002] A press machine is a machine that applies pressure to a target and presses it into the corresponding component. It is often used in the production and assembly of bearings and motors. The bearing is placed on the corresponding placement device, and then the part is placed in the middle of the bearing. The part is then pressed into the bearing by a hydraulic press. It is one of the commonly used assembly machinery equipment.

[0003] In order to ensure smooth press-fitting, the bearings and parts need to be positioned, otherwise the parts cannot enter the bearings, which will cause the parts and bearings to be damaged and scrapped under pressure. Currently, positioning is basically done by clamping, which requires motor drive control and a slow process, which will delay the overall press-fitting efficiency. For this purpose, a press-fitting mechanism with clamping and positioning functions is established. Utility Model Content

[0004] The technical solution adopted by the utility model to solve the technical problem is: a press-fitting mechanism with a clamping and positioning function, comprising a column, one end of which is fixedly connected to a placement column, a storage groove is opened in the middle of the top side wall of the placement column, a through hole is opened in the middle of the bottom side wall of the storage groove, and a positioning rod is inserted and movably connected in the through hole, six side grooves are evenly opened on the inner wall of the storage groove and the side wall close to the top edge, and a rotating shaft is set in each of the side grooves.

[0005] As a preferred technical solution of the utility model, a side wall of one side of the rotating shaft is fixedly connected with a clamping plate, and a side wall of the rotating shaft away from the clamping plate is fixedly connected with a control plate, and the control plate is an outwardly inclined structure.

[0006] As a preferred technical solution of the utility model, the two ends of the rotating shaft that are far away from each other are rotatably connected to the inner walls of the side grooves on both sides through torsion springs. The side groove is an L-shaped structure, and the end of the side groove opposite to the positioning rod is an arc structure and is fixedly connected with an anti-slip rubber pad.

[0007] As a preferred technical solution of the utility model, an inner cavity is opened inside the column, and the top side wall of the positioning rod is provided with anti-slip grooves. The positioning rod is fixedly connected to a follower block through one end passing through the through hole, and a spring is provided at the end of the follower block away from the positioning rod.

[0008] As a preferred technical solution of the utility model, the spring is fixedly connected to the bottom side wall of the inner cavity through one end thereof, the opening of the inner cavity corresponds to the placement column, the follower block extends into the inner cavity, and the spring is fixedly connected to the side wall of the follower block away from the positioning rod through the top end.

[0009] The utility model has the following advantages: when it is necessary to place a bearing, the bearing is sleeved on the positioning rod and then placed in the storage groove. As the storage groove falls, the control plate will be squeezed, and the rotation of the rotating shaft can drive the clamping plate to squeeze the outer wall of the bearing, thereby achieving the clamping and positioning effect of the bearing. A non-slip pad is provided at the top of the positioning rod, and parts can be placed on it. Because the positioning rod is located in the middle of the bearing, the parts placed on the positioning rod can be smoothly pressed into the bearing, effectively avoiding damage to the parts and bearings during the pressing process due to the position offset of the parts, and improving the yield rate. After the pressing is completed, the bearing can be taken out of the storage groove by lifting the positioning rod. The whole process does not need to be driven by a motor or electric component, and the efficiency of taking and placing can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] Please refer to Figure 1-3 The utility model discloses a press-fitting mechanism with a clamping and positioning function, comprising a column 1, one end of which is fixedly connected to a placement column 2, a placement groove 3 is provided in the middle of the top side wall of the placement column 2, a through hole is provided in the middle of the bottom side wall of the placement groove 3, and a positioning rod 4 is inserted and movably connected in the through hole, six side grooves 8 are evenly provided on the inner wall of the placement groove 3 and the side wall close to the top edge, and a rotating shaft 9 is provided in each side groove 8;

[0016] A clamping plate 10 is fixedly connected to a side wall of the rotating shaft 9, and a control board 11 is fixedly connected to the side wall of the rotating shaft 9 away from the clamping plate 10. The control board 11 is an outwardly inclined structure. The two ends of the rotating shaft 9 away from each other are rotatably connected to the inner walls of the side groove 8 on both sides through torsion springs. The side groove 8 is an L-shaped structure, and the end of the side groove 8 opposite to the positioning rod 4 is an arc structure and is fixedly connected with a non-slip rubber pad.

[0017] The preferred effect of this scheme is to align the center hole of the bearing to be pressed with the positioning rod 4, and then put the bearing into the storage slot 3. After the center hole is aligned with the positioning rod 4, just loosen it and let the bearing fall naturally. No additional operation is required, which improves the efficiency of placement. When the bearing falls into the storage slot 3, it will squeeze the control board 11, and the control board 11 drives the rotating shaft 9 to rotate, thereby driving the clamping plate 10 to move, and finally form a state of clamping the bearing. Because it is driven by the bearing itself, it can effectively save energy consumption. Because the size and moving range of all clamping plates 10 are certain, when the six clamping plates 10 clamp the bearing, they will naturally push the bearing to move to the center point. At the same time, the stability of the bearing after placement can be further improved through the limitation of the positioning rod 4. After the bearing is placed, the part can be placed on the top of the positioning rod 4. After the processing process, the bearing is pulled upward so that its pressure will cause the clamping plate 10 to expand naturally outward through the torsion spring, thereby loosening the clamping limitation on the bearing.

[0018] An inner cavity 7 is opened inside the column 1, and the top side wall of the positioning rod 4 is provided with anti-slip grooves. The positioning rod 4 is fixedly connected to a follower block 5 through one end passing through the through hole, and a spring 6 is provided at the end of the follower block 5 away from the positioning rod 4. The spring 6 is fixedly connected to the bottom side wall of the inner cavity 7 through one end. The opening of the inner cavity 7 corresponds to the placement column 2, the follower block 5 extends into the inner cavity 7, and the spring 6 is fixedly connected to the side wall of the follower block 5 away from the positioning rod 4 through the top.

[0019] As a preferred effect of this solution, in order to prevent the positioning rod 4 from affecting the pressing effect, the positioning rod 4 is fixedly connected to the follower block 5. When pressed downward, the follower block 5 will be pushed to synchronously descend inside the inner cavity 7, thereby compressing the spring 6 to make it contract. The contraction of the spring 6 can alleviate the stamping damage to the column 1 during pressing, thereby increasing the service life of the equipment.

[0020] Specifically, when the utility model is used, the bearing is placed in the corresponding storage groove 3, and then the parts are placed on the positioning rod 4, because the anti-slip grooves are set to prevent the parts from slipping and prevent them from moving without the driving of unexpected force. After the placement is completed, the hydraulic cylinder is started to press the collar part to press it into the bearing. In order to facilitate the later removal of the bearing, the depth of the storage groove 3 should be less than the height of the bearing. The specific ratio can be adjusted according to actual needs. Therefore, when the processing is completed, the exposed part of the bearing can be directly held and pulled out of the storage groove 3. As the bearing is pulled out, the control board 11 will be lost, so the clamping plate 10 will open, and when the hydraulic cylinder is raised after the press-fitting is completed, the positioning rod 4 is also pushed upward under the action of the spring 6. Because the parts have been pressed into the bearing, the bearing will also be pushed out of the storage groove 3 as the positioning rod 4 is pushed up, thereby improving the unloading efficiency.

[0021] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0022] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
