The electronic radiator is a radiating fin for radiating high-power electronic components, generally has no external power supply, and radiates heat in a natural cooling mode.

Electronic heat sinks are generally connected to electronic components by screws, and therefore, screw holes need to be formed in a bottom plate of the electronic heat sink. The screw hole of the existing electronic radiator is generally formed by matching and processing one drilling device and one tapping device, and two independent devices need to clamp the electronic radiator twice in the processing process, so that the processing efficiency is low.

Therefore, the purpose of one-time clamping and multi-station step-by-step processing can be achieved by arranging the multi-station positioning rotary table. A problem with the turret structure is that the support structure of the turret is located in the center of the table and the machining position is located outside the table. Because both the drilling mechanism and the tapping mechanism exert downward force on the table plate, the pressure on the outer side of the table plate is increased, the table plate deflects downwards, and the table plate can tip over in severe cases.

Fig. 1 to 3 are schematic structural views of a bearing and positioning mechanism of a multi-station positioning rotary table according to some embodiments of the present application, and the bearing and positioning mechanism of the multi-station positioning rotary table according to the present application will be described below with reference to fig. 1 to 3. It should be noted that fig. 1-3 are only examples, and do not limit the specific shape and structure of the positioning mechanism of the multi-station positioning turret.

Referring to fig. 1 to 3, in some embodiments, a bearing positioning mechanism 2 of a multi-station positioning rotary table includes a base 3, a tensioning support 24, a tensioning cylinder 25, and a bearing positioning assembly; the tensioning support 24 is fixedly arranged on the base 3; the tensioning cylinder 25 is fixedly arranged on the tensioning support 24, and the end of the telescopic rod of the tensioning cylinder 25 is provided with a tensioning block 26; the bearing positioning assembly comprises a floating seat 21 positioned above the table plate 1 and a tensioning seat 22 positioned below the table plate 1, the floating seat 21 and the tensioning seat 22 are fixedly connected through a guide column 27 movably connected with the table plate 1, and the height of the guide column 27 is greater than the thickness of the table plate 1; an elastic component is arranged between the floating seat 21 and the table plate 1, and a tensioning groove 23 matched with a tensioning block 26 is arranged at the bottom of the tensioning seat 22.

In the present exemplary embodiment, the tensioning mount 24 is first mounted in the corresponding processing position of a processing device, such as a drilling or tapping device. The floating seat 21 is used for installing a tool clamp and a workpiece.

Therefore, the basic operation process of the bearing and positioning mechanism 2 is that in the process that the table plate 1 rotates to the processing station, the telescopic rod of the tensioning cylinder 25 is in an extending state, and the tensioning block 26 fixed at the end head thereof slides into the tensioning groove 23 of the tensioning seat 22 in the process that the table plate 1 rotates. After the table plate 1 rotates to the processing station, the telescopic rod of the tensioning cylinder 25 retracts, the tensioning seat 22 is pulled to move downwards, the tensioning seat 22 simultaneously pulls the floating seat 21 to move downwards through the action of the guide column 27, so that the whole bearing positioning assembly is driven to move downwards, and the tensioning seat 22 is placed on the tensioning support 24. At this point, the elastic component is compressed to store elastic potential energy.

Since the height of the guide posts 27 is greater than the thickness of the platform 1, when the tensioning seat 22 is placed on the tensioning seat 24, the floating seat 21 is not in contact with the platform 1, and a gap is still formed between the floating seat 21 and the platform 1. Thus, when the drilling mechanism or the tapping mechanism processes the workpiece, the acting force born by the workpiece is transmitted to the tensioning support 24 through the floating seat 21, the guide column 27 and the pull-down seat. In the whole machining process, the table plate 1 does not bear the machining acting force any more, so that the table plate 1 is prevented from being damaged due to the acting force, and the service life of the multi-station positioning rotary table is effectively prolonged.

Meanwhile, in the whole processing process, the position bearing and repositioning mechanism 2 can also ensure that the processed electronic radiator is fixed in position, so that the electronic radiator is ensured not to have position deviation in the whole processing process, and the processing precision of the electronic radiator is improved.

After the processing is finished, the telescopic rod of the tensioning cylinder 25 extends out, the elastic assembly releases the stored elastic potential energy, and the bearing and repositioning assembly resets under the combined action of the tensioning cylinder 25 and the elastic assembly. The table plate 1 is rotated again and the tightening slot 23 is disengaged from the tightening block 26.

In particular, the purpose of the elastic assembly is to keep the floating seat 21 spaced from the table disc 1. Without the elastic member, the floating seat 21 is pressed down into contact with the table plate 1 by the gravity of the floating seat 21, and in this condition, the tightening cylinder 25 acts to pull down the table plate 1 together with the floating seat 21, thereby causing the table plate 1 to be deviated.

Preferably, the tightening slot 23 includes a transverse slot and a longitudinal slot arranged in a T shape, an upper end of the longitudinal slot communicates with the transverse slot, and a lower end of the longitudinal slot penetrates the tightening block 26.

The transverse grooves and the longitudinal grooves which are arranged in a T shape can be effectively matched with the tensioning block 26, so that the tensioning block 26 can complete sliding in and pulling down with the tensioning block 26.

Preferably, the tensioning block 26 is of a circular structure, the tensioning block 26 is movably clamped in a transverse groove of the tensioning groove 23, and an expansion rod of the tensioning cylinder 25 extends out of a longitudinal groove of the tensioning groove 23.

Wherein, because the motion trail of the table plate 1 is circular, the tensioning block 26 also moves in an arc shape, and the tensioning block 26 with a circular structure can adapt to the motion trail of the tensioning groove 23, so that the tensioning groove 23 smoothly slides into the tensioning groove 23. And the tensioning block 26 with the circular structure can reduce the contact area between the tensioning block 26 and the tensioning groove 23, and reduce the friction force between the tensioning block 26 and the tensioning groove 23.

Preferably, the outer side groove wall of the transverse groove is of a linear structure, and the inner side groove wall of the transverse groove is of an arc structure.

Wherein, the inner side groove wall of the transverse groove is in an arc structure and can be matched with the motion track of the table tray 1, so that the tensioning block 26 can smoothly slide into the tensioning groove 23. The combination of the linear structure of the outer side groove wall of the transverse groove and the arc structure of the inner side groove wall can increase the size of the opening of the tensioning groove 23, and is convenient for the tensioning block 26 to carry out tensioning in the tensioning groove 23.

Preferably, the table plate 1 is provided with a guide sleeve 28 adapted to the guide post 27.

The guide sleeve 28 can reduce the friction force of the movement of the guide post 27 and guide the movement of the guide post 27.

Preferably, the elastic assembly includes a support 211, a guide 210, and a support spring 29; the supporting piece 211 is embedded on the table plate 1, and a movable hole with an opening at the upper end is arranged on the supporting piece 211; the upper end of the guide piece 210 is fixedly connected with the bottom of the floating seat 21, and the lower end of the guide piece 210 extends into the movable hole; the supporting spring 29 is sleeved on the guide member 210, the upper end of the supporting spring 29 is propped against the floating seat 21, and the lower end of the supporting spring 29 is propped against the bottom surface of the movable hole.

Wherein, during the up-and-down movement of the floating seat 21, the guide member 210 will move up and down in the movable hole. The guide member 210 is used for guiding the supporting spring 29, and the supporting spring 29 sleeved on the guide member 210 cannot deflect, so that the supporting spring can be compressed or reset in the vertical direction, and the direction of the elastic supporting force of the floating seat 21 is stable.

The above is an embodiment of the present invention. The embodiments and specific parameters in the embodiments are only used for clearly illustrating the verification process of the utility model and are not used for limiting the patent protection scope of the utility model, which is defined by the claims, and all the equivalent structural changes made by using the contents of the description and the drawings of the utility model should be included in the protection scope of the utility model.
