Description

Technical Field

[0001] The present application relates to the technical field of cross-axis processing, and in particular to a cross-axis processing clamping device. Background Art

[0002] Cross-axis machining clamping devices are widely used in mechanical manufacturing, precision machining, automobile manufacturing, aerospace and other fields. Especially in the machining process of complex workpieces such as cross-axis, this device can play an important role.

[0003] Conventional clamping devices for clamping cross shafts will clamp the four journals of the cross shaft through the clamping parts during operation to ensure that the cross shaft will not move. However, when processing the cross shaft, most existing processing devices will cover the journal of the cross shaft with a sleeve before processing to ensure that the two ends of the cross shaft can be symmetrical after processing. The clamping parts directly connected to the journal may block the normal operation of the sleeve. For example, when drilling the end face of the cross shaft, if the drilling hole is deep, the sleeve may need to be covered on the entire journal. As a result, the processing parts cannot be properly contacted with the journal of the cross shaft for processing, affecting the quality of the finished cross shaft. Therefore, those skilled in the art provide a cross shaft processing clamping device to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a cross-axis processing clamping device to solve the problem that the conventional clamping device for clamping the cross-axis proposed in the above-mentioned background technology clamps the four journals of the cross-axis through the clamping parts during operation, so as to ensure that the cross-axis does not move. However, when most existing processing devices process the cross-axis, they will cover the journal of the cross-axis with a sleeve before processing, so as to ensure that the two ends of the cross-axis can be symmetrical after processing. The clamping parts are directly connected to the journals, which may block the normal operation of the sleeves, thereby making it impossible for the processing parts to contact the journals of the cross-axis normally for processing, affecting the quality of the processed cross-axis products.

[0024] The following is combined with Figure 1-4 This application is described in further detail.

[0025] The present application embodiment discloses a cross shaft processing clamping device, referring to Figure 1-4 , including a processing table 1 and two first mounting plates 2 fixedly mounted on a cross-axis processing machine tool, a plurality of mounting mechanisms for placing a cross-axis are mounted on the outer side of the top of the processing table 1, a connecting plate 3 is mounted on one side of the top of the two first mounting plates 2, a cylinder 4 is mounted on the bottom end of the two connecting plates 3, a top plate 5 is fixedly mounted on the end of the output shaft of the cylinder 4, and a clamping mechanism for cooperating with the mounting mechanism to fix the cross-axis is mounted on the other side of the two first mounting plates 2 through a connecting rod; the mounting mechanism includes a second mounting plate 6, the second mounting plate 6 is Movable grooves 7 are provided on all sides of the mounting plate 6, and positioning plates 8 are movably installed in the four movable grooves 7. A sliding groove 9 is provided in the middle of the positioning plate 8, and a slider 10 is movably installed in the sliding groove 9. Both sides of the slider 10 are respectively fixedly connected to both sides of the movable groove 7; the clamping mechanism includes a third mounting plate 11, and a push rod 12 is movably installed on one side of the third mounting plate 11. A positioning block 13 is installed at the bottom end of the push rod 12, and a first spring 14 is installed between the positioning block 13 and the third mounting plate 11, and the first spring 14 is sleeved on the push rod 12.

[0026] By adopting the above technical solution, the utility model, through the installation mechanism and the clamping mechanism, facilitates the cylinder 4 to drive the top plate 5 to push the two mutually symmetrical positioning plates 8 upward, so that the cross shafts on the two positioning plates 8 move upward, so that the positioning block 13 is pressed against the top of the cross shaft, and the two positioning plates 8 clamp the cross shaft, and the journals at the other two ends of the cross shaft can be in a suspended state, so as to facilitate the processing of the two journals. After the processing is completed, the cylinder 4 drives the top plate 5 to reset downward, and the two positioning plates 8 can be reset by the elastic force of the second spring 17, and the push rod 12 can also be reset by the elastic force of the first spring 14. When the cross shaft is clamped, it is avoided that the positioning plate 8 at the processing location will block the operation of the processing mechanism, and the installation grooves 15 on the two positioning plates 8 cooperate with the positioning blocks 13 to press the cross shaft, so as to avoid the cross shaft from moving or offsetting during the processing.

[0027] Reference Figure 1-4 The top of the positioning plate 8 is provided with a mounting groove 15, and the mounting groove 15 is arranged in an arc shape. The slider 10, the second mounting plate 6 and the movable groove 7 are fixedly connected by bolts.

[0028] By adopting the above technical solution, the mounting groove 15 is arranged in an arc shape, so that the surface of the mounting groove 15 can fit with the shaft neck of the cross shaft, thereby preventing the cross shaft from moving due to vibration in the mounting groove 15, and conveniently setting the positioning plates 8 of the mounting grooves 15 of various sizes, so as to facilitate the disassembly and installation of the positioning plates 8 with the matching bolts, thereby facilitating the clamping processing of cross shafts of various sizes, thereby improving the applicability of the device.

[0029] Reference Figure 1-4 A limit rod 16 is fixedly installed in the movable groove 7, the limit rod 16 is movably connected to the slider 10, and a second spring 17 is sleeved on the limit rod 16, and the second spring 17 is arranged at the bottom end of the slider 10. The top end of the push rod 12 passes through the third mounting plate 11, and the top of the push rod 12 is threadedly installed with an adjusting nut 18.

[0030] By adopting the above technical solution, it is convenient to adjust the distance between the bottom end of the push rod 12 and the cross shaft by adjusting the nut 18, so as to facilitate the adjustment of the strength of the positioning block 13 and the positioning plate 8 to clamp the cross shaft. At the same time, it is also convenient to adjust the elastic force of the first spring 14 to the top positioning block 13 after the top plate 5 is reset. The elastic force of the first spring 14 can be transmitted to the cross shaft and the positioning plate 8 through the positioning block 13, thereby affecting the reset speed of the positioning plate 8. At the same time, the setting of the second spring 17 can enable the positioning plate 8 to be reset under the drive of the elastic force of the second spring 17 after the positioning plate 8 is separated from the top plate 5.

[0031] Reference Figure 1-4The output shaft of the cylinder 4 is arranged through the connecting plate 3, and the top plate 5 is arranged at the bottom ends of the two oppositely arranged positioning plates 8. The width of the top plate 5 is smaller than the width of the two oppositely arranged positioning plates 8.

[0032] By adopting the above technical solution, when the top plate 5 pushes the two positioning plates 8 upward, the other two positioning plates 8 will not contact the top plate 5, thereby preventing the cylinder 4 from driving the top plate 5 to drive the other two positioning plates 8 to move, causing the two journals of the cross shaft to not be suspended in the air, which will directly affect the processing of the two journals.

[0033] Reference Figure 1-4 The processing table 1 is arranged in a circular convex shape.

[0034] By adopting the above technical solution, it is convenient to install the mounting mechanism on the processing table 1, so that the mounting mechanism can rotate with the processing table 1, thereby facilitating the processing of the two unprocessed cross shaft journals.
