DETAILED DESCRIPTION

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0033] Refer to the following Figures 1 to 6 , describing a hollow shell processing device according to an embodiment of the utility model.

[0034] See also Figure 3 According to the embodiment of the utility model, the hollow shell processing device includes a support plate 1, a positioning seat 2, a first actuator 3 and a second actuator 5. The support plate 1 is provided with a plurality of hollow holes 26 along the circumferential direction. The positioning seat 2 is annular as a whole and is arranged on the top surface of the support plate 1 for positioning the hollow shell 201. A plurality of first actuators 3 are arranged inside the positioning seat 2 along the circumferential direction for radially pressing against the inner side surface of the hollow shell 201. A plurality of second actuators 5 are arranged on the bottom surface of the support plate 1 along the circumferential direction for axially pressing against the end surface of the hollow shell 201.

[0035] The support plate 1 mainly plays a supporting role, and is used to support the positioning seat 2, the first actuator 3 and the second actuator 5. The size, shape and number of the hollow holes 26 are set according to actual needs, and there is no limitation on this. For example, the hollow holes 26 are close to the shape of a fan. The hollow hole 26 can be passed through by the hollow housing 201. The hollow hole 26 can also play a role in chip removal.

[0036] The positioning seat 2 is detachably connected to the support plate 1, and can be connected by bolts. The positioning seat 2 can be positioned with the hollow shell by using an outer contour or positioning pin hole that matches the hollow shell 201.

[0037] The first actuator 3 and the second actuator 5 can use electric cylinders, air cylinders or hydraulic cylinders and other driving devices that can provide linear motion. The first actuator 3 and the second actuator 5 appear in pairs and act together on a hollow housing 201. The first actuator 3 and the second actuator 5 can be connected to the support plate 1 using fasteners.

[0038] When the hollow shell processing device is in use, the hollow shell 201 is positioned with the positioning seat 2, and the outer side of the hollow shell 201 contacts the positioning seat 2. The telescopic rod of the first actuator 3 extends radially to clamp the hollow shell 201, and the telescopic rod of the second actuator 5 retracts to adjust the bottom end faces of all the hollow shells 201 to the same plane. During processing, the top surface and side wall of the hollow shell 201 are processed first, and after the processing is completed, the hollow shell processing device is turned over to process the bottom surface of the hollow shell 201.

[0039] According to the hollow shell processing device of the embodiment of the utility model, a positioning seat, a first actuator and a second actuator are provided. The positioning seat can position the hollow shell and support the hollow shell in place so that it is not deformed by force during processing. The first actuator presses the inner side surface of the hollow shell radially to prevent the hollow shell from moving radially. The second actuator presses the bottom end surface of the hollow shell axially to prevent it from moving up and down during processing and does not cause dimensional deviation.

[0040] In some embodiments, in combination Figure 3 , Figure 5 As shown, both ends of the support plate 1 are provided with connection holes 11 for connecting to the machining center turntable. After the connection holes 11 are connected to the machining center turntable, the machining center turntable rotates along the X-axis after the top surface of the hollow shell is processed, and its bottom surface is facing upward, so that the tool can process the process features of the bottom surface of the hollow shell. The number of connection holes 11 is set according to actual needs, and there is no specific limitation for comparison.

[0041] In some embodiments, in combination Figure 1 , Figure 2 As shown, the hollow shell 201 has two glue pouring grooves before processing, namely the first glue pouring groove 202 and the second glue pouring groove 203. After the glue pouring, the hollow shell 201 needs to be processed to have at least one of the process features of the step surface 208, the orifice 206 and the notch 207 for subsequent assembly. The two end faces of the hollow shell 201 also need to be processed. The outer side surface of the hollow shell 201 has a protrusion 209. The two ends of the hollow shell have a shell flange 204 extending to the end face and a shell buckle groove 205 respectively.

[0042] The inner wall of the positioning seat 2 is provided with a depression, and the protrusion 209 is adapted to the depression. The number of the protrusion 209 is at least one. The contour of the inner wall of the positioning seat 2 is consistent with the contour of the outer side of the hollow shell 201, so that the inner wall of the positioning seat 2 can be completely fitted with the outer side of the hollow shell 201. At the same time, in order to prevent the hollow shell from being deformed under force during processing, the height of the positioning seat 2 is not less than 60% of the height of the hollow shell 201, and the supporting effect on the hollow shell 201 is better.

[0043] The support plate 1 is provided with a center hole 12 in the positioning seat 2, and the support plate 1 is provided with at least one chip removal hole 13 outside the positioning seat 2. Both the center hole 12 and the chip removal hole 13 can remove cutting fluid and metal debris, keep the cutting area clean, and avoid accumulation affecting the processing. The number and position of the chip removal holes 13 are designed according to actual needs and are not specifically limited thereto.

[0044] In some embodiments, Figure 3As shown, the side wall of the positioning seat 2 is provided with a characteristic through hole 22, and the upper end of the side wall of the positioning seat 2 is provided with a characteristic groove 21. During processing, the drill bit can pass through the characteristic through hole 22 to process the orifice 206 or the notch 207. The characteristic groove 21 will not cause interference when the milling cutter processes the step surface 208.

[0045] The hollow shell processing device also includes a first anti-error block 8 and a second anti-error block 9. The upper end of the side wall of the positioning seat 2 is provided with a plurality of anti-error block grooves 23. The first anti-error block 8 is arranged in the anti-error block groove 23 to position the two ends of the hollow shell 201. The second anti-error block 9 is arranged on the bottom surface of the support plate 1 to position the lower side of the outer side wall of the hollow shell 201. A countersunk hole 24 is provided in the anti-error block groove 23, and a fastener can be installed in the countersunk hole 24 to connect the support plate 1 and the positioning seat 2 together.

[0046] The hollow shell 201 has different process characteristics in different directions, so the direction needs to be determined when clamping the hollow shell. To avoid clamping errors, the first end of the first error-proofing block 8 and the second error-proofing block 9 is provided with an error-proofing groove adapted to the shell flange 204, and the second end is provided with an error-proofing flange adapted to the shell buckle groove. The first error-proofing block 8 can be connected to the error-proofing block groove 23 by fasteners. The second error-proofing block 9 can be connected to the bottom surface of the support plate 1 by fasteners, and the connection strength is relatively high.

[0047] In some embodiments, in combination Figure 3 , Figure 4 As shown, the hollow shell processing device also includes a profiling block 4 and a cylinder seat 15. The first actuator 3 is an electric cylinder, a pneumatic cylinder or a hydraulic cylinder. The profiling block 4 is installed at the end of the telescopic rod of the first actuator 3. The shape of the profiling block 4 is adapted to the inner side of the processed hollow shell 201, so that the hollow shell 201 is balanced in force and does not deform. The cylinder seat 15 is connected to the support plate 1, and the first actuator 3 is connected to the cylinder seat 15. The cylinder seat 15 can provide a stable installation platform for the first actuator 3.

[0048] In some embodiments, in combination Figure 3 , Figure 4 As shown, the first actuator 3 is a cylinder or a hydraulic cylinder, and the plurality of second actuators 5 are angle cylinders or angle hydraulic cylinders. An angle cylinder is a special type of actuator that can convert the pressure energy of compressed air or hydraulic oil into the rotational motion of a piston rod. The plurality of second actuators 5 can be controlled individually. When the pressing arm 51 of the second actuator is fully extended, the pressing arm 51 points to the outside of the center hole 12. After retracting to a preset position, the pressing arm 51 will deflect 90 degrees and point to the center hole 12, and finally press the bottom surface of the hollow shell 201.

[0049] In one example, the cylinder of the second actuator 5 is disposed through the support plate 1 , and the positioning seat 2 is provided with an avoidance groove 25 adjacent to the second actuator 5 to reserve installation space for the second actuator 5 .

[0050] The hollow shell processing device further includes an adapter plate 14, a flow channel is provided in the positioning seat 2, and the adapter plate 14 is arranged on the bottom surface of the support plate 1. After the adapter plate 14 is connected to the support plate 1, a complete flow channel is defined to allow compressed air or hydraulic oil to flow therein.

[0051] In addition, a first pressure gauge 6 and a second pressure gauge 7 are provided on the support plate 1. The former can display the clamping force of the first actuator 3, and the latter can display the clamping force of the second actuator, so as to facilitate real-time observation of pressure.
