A clamping device for manufacturing automotive generator end caps

Abstract

This utility model discloses a clamping device for producing automotive generator end caps, including a mounting frame and a worktable. Several sliding rods are slidably connected to the mounting frame, and a clamping rod is hinged to the top of the sliding rod. When clamping the end cap, the end of the clamping rod away from the sliding rod abuts against the top surface of the end cap. A positioning rod with its top hinged to the clamping rod is fixedly connected to the mounting frame. Therefore, when clamping irregularly shaped end caps, the end cap is placed on the worktable, and the sliding rod is slid downwards. As the sliding rod slides, the clamping rod rotates and abuts against the top surface of the end cap. Sliding the sliding rod upwards further allows the clamping rod to clamp the end cap tightly onto the worktable. Since the clamping rod contacts the top surface of the end cap, it can effectively prevent the uneven edges of the irregularly shaped end cap from causing unstable clamping.

Description

Technical Field

[0001] This utility model belongs to the field of end cap processing, and relates to clamping devices, particularly a clamping device for producing automotive generator end caps. Background Technology

[0002] In motor manufacturing, it is necessary to clamp the motor bearing end cover to the bearing. During the clamping process, a pressure is applied to the motor bearing end cover. If the motor bearing end cover is placed directly on the processing plate without being fixed, it is easy for it to shift under this pressure. Therefore, nowadays, clamping devices are generally used to fix the product in place before processing.

[0003] For example, a clamping device for machining the end face of an automotive bearing cover, disclosed in CN205799309U, includes a clamping plate. The clamping plate has a disc-shaped structure. A fixing connector is fixedly connected to the outer side of the clamping plate, and a telescopic clamping device is fixedly connected to the inner side of the fixing connector. The telescopic clamping device includes a hydraulic jack. A connecting rod pipe is provided at the inner end of the hydraulic jack. One end of the connecting rod pipe is sleeved with the inner side of the connecting rod. The other end of the connecting rod is fixedly connected to a clamping plate. A spring is fixedly connected between the clamping plate and the inner end of the hydraulic jack. A rubber pad is fixedly connected to the inner side of the clamping plate.

[0004] The above-mentioned end cap clamping device is more suitable for round end caps in order to achieve a stable clamping effect. However, most end caps nowadays have irregular edges, and the above method of clamping will still result in unstable clamping. Utility Model Content

[0005] This utility model provides a clamping device for the production of automotive generator end caps, which can firmly clamp end caps with irregular edges.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a clamping device for producing automobile generator end caps, including a mounting frame and a workbench fixedly connected to the mounting frame. A plurality of sliding rods are slidably connected to the mounting frame, and a clamping rod is hinged to the top of the sliding rod. When clamping the end cap, the end of the clamping rod away from the sliding rod abuts against the top surface of the end cap. A positioning rod with its top hinged to the clamping rod is fixedly connected to the mounting frame.

[0007] A further preferred embodiment of this utility model is as follows: a rubber pad is fixedly connected to one end of the clamping rod near the worktable, and the rubber pad deforms when it comes into contact with the end cap.

[0008] A further preferred embodiment of this utility model is as follows: the bottom ends of several sliding rods are all connected to the same connecting rod, and a cylinder is fixedly connected below the mounting bracket, with the piston of the cylinder fixedly connected to the connecting rod.

[0009] A further preferred embodiment of this invention is that both the slide rod and the positioning rod are hinged to the clamping rod via pins.

[0010] A further preferred embodiment of this utility model is that at least two clamping rods are provided, and the two clamping rods are symmetrically arranged with the central axis of the worktable as the axis of symmetry.

[0011] A further preferred embodiment of this invention is that there is a gap between the positioning rod and the worktable.

[0012] A further preferred embodiment of this utility model is as follows: the worktable includes a fixed seat and a movable seat that slides outside the fixed seat. Several springs are fixedly connected between the fixed seat and the movable seat. When the end cap is clamped, the movable seat slides and the springs deform.

[0013] A further preferred embodiment of this utility model is as follows: a plurality of support shafts are fixedly connected between the fixed seat and the movable seat, the spring is sleeved on the support shaft, and the support shaft is elastic.

[0014] Compared with the prior art, this utility model includes a mounting frame and a worktable. Several sliding rods are slidably connected on the mounting frame, and a clamping rod is hinged to the top of the sliding rod. When clamping the end cap, the end of the clamping rod away from the sliding rod abuts against the top surface of the end cap. A positioning rod with its top hinged to the clamping rod is fixedly connected to the mounting frame. Therefore, when clamping an irregular end cap, the end cap is placed on the worktable, and the sliding rod is slid downwards. At this time, as the sliding rod slides, the clamping rod rotates and abuts against the top surface of the end cap. Then, the sliding rod is slid upwards so that the clamping rod can clamp the end cap on the worktable. Since the clamping rod is in contact with the top surface of the end cap, it can effectively avoid the situation where the irregular end cap is unstable due to uneven edges.

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0020] Figures 1-3 As shown, a clamping device for producing an automotive generator end cover includes a mounting frame 1 and a workbench fixedly connected to the mounting frame 1. Several sliding rods 4 are slidably connected to the mounting frame 1, and a clamping rod 5 is hinged to the top of the sliding rod 4. When clamping the end cover, the end of the clamping rod 5 away from the sliding rod 4 abuts against the top surface of the end cover.

[0021] Figures 1-3 As shown, when clamping an irregularly shaped end cap, the end cap is placed on the worktable, and the slide bar 4 is slid upward. As the slide bar 4 slides, the clamping rod 5 rotates so that one end of it abuts against the top surface of the end cap. By further sliding the slide bar 4, the clamping rod 5 clamps the end cap, thus firmly clamping the end cap on the worktable. In this design, the clamping rod 5 contacts the top surface of the end cap, which can effectively avoid the edge of the end cap, making clamping easier and providing a better and more stable clamping effect.

[0022] Figures 1-3 As shown, a rubber pad 10 is fixedly connected to one end of the clamping rod 5 near the worktable. When the rubber pad 10 comes into contact with the end cap, the rubber pad 10 deforms.

[0023] Figures 1-3As shown, when the clamping rod 5 clamps the end cap on the worktable, the rubber pad 10 deforms due to the deformation of the second denture, thus tightly adhering to the end cap, further improving the clamping effect. Furthermore, if there are textures or unevenness on the surface of the end cap, the rubber pad 10 can better adhere to the surface of the end cap, thereby ensuring the stability of the clamping. In addition, the rubber has an anti-slip effect, which can prevent the end cap from sliding during processing and affecting the processing, further improving the stability of the clamping.

[0024] Figures 1-3 As shown, at least two clamping rods 5 are provided, and the two clamping rods 5 are symmetrically arranged with the central axis of the worktable as the axis of symmetry.

[0025] Figures 1-3 As shown, setting multiple clamping rods 5 can effectively increase the clamping effect, making the end cap more stable. The symmetrically arranged clamping rods 5 can make the clamped end cap evenly stressed, preventing the end cap from shaking during processing and further improving the stability of the clamping.

[0026] Figures 1-3 As shown, the bottom ends of several sliding rods 4 are all connected to the same connecting rod 9. A cylinder 7 is fixedly connected below the mounting bracket 1, and the piston of the cylinder 7 is fixedly connected to the connecting rod 9.

[0027] Figures 1-3 As shown, when it is necessary to clamp or release the end cap, the cylinder 7 is activated. At this time, the piston of the cylinder 7 drives the connecting rod 9 and several sliding rods 4 fixed on the connecting rod 9 to slide together, thereby achieving the purpose of releasing or clamping the end cap. In this design, the connecting rod 9 plays the role of simultaneously driving multiple sliding rods 4 to slide together, further synchronizing the clamping process of the clamping rod 5.

[0028] Figures 1-3 As shown, a positioning rod 6 with its top end hinged to the clamping rod 5 is fixedly connected to the mounting bracket 1. Both the sliding rod 4 and the positioning rod 6 are hinged to the clamping rod 5 through the pin 8. There is a gap 11 between the positioning rod 6 and the worktable.

[0029] Figures 1-3 As shown, the positioning rod 6 ensures that the clamping rod 5 can rotate when the slide rod 4 slides, and the gap 11 between the positioning rod 6 and the worktable makes it easy to place end caps of different sizes.

[0030] Figures 2-4 As shown, the worktable includes a fixed base 3 and a movable base 2 that slides outside the fixed base 3. Several springs 13 are fixedly connected between the fixed base 3 and the movable base 2. When the end cap is clamped, the movable base 2 slides and the springs 13 deform.

[0031] Figures 2-4As shown, when clamping the end cap, the end cap is placed above the movable seat 2, and the cylinder 7 is further activated. At this time, the piston of the cylinder 7 drives the connecting rod 9 and several sliding rods 4 to slide upward. As the sliding rods 4 slide, the clamping rod 5 rotates and forms contact with the top surface of the end cap. The clamping rod 5 is further rotated. At this time, with the pressure generated by the clamping rod 5, the movable seat 2 slides downward, and the spring 13 deforms until the spring 13 is compressed to its limit. At this time, the end cap is clamped. The deformed spring 13 can exert a reverse force on the end cap, thereby firmly clamping the end cap between the movable seat 2 and the clamping rod 5. This design further improves the clamping effect of the clamping device.

[0032] Figures 2-4 As shown, a number of support shafts 12 are fixedly connected between the fixed seat 3 and the movable seat 2. The spring 13 is sleeved on the support shaft 12. The support shaft 12 is elastic. The support shaft 12 also deforms during the clamping process of the end cover, thereby exerting a reaction force on the end cover, improving the clamping effect, and effectively preventing the spring 13 from tilting during the clamping process and affecting the clamping effect.
