Description

Technical Field

[0001] This utility model relates to the field of clamps, and in particular to a turbocharger gas seal clamp. Background Technology

[0002] The turbocharger air seal 4 needs to be drilled and surface-treated using a machining center, such as machining the center hole 4a, machining the upper end face of the boss 4b, machining the upper end face of the large circle 4c, and machining the groove 4d between the boss 4b and the large circle 4c. Since there are many areas to be machined in the turbocharger air seal 4, how to firmly clamp it without affecting its machining is a technical problem that urgently needs to be solved. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a turbocharger gas seal cover clamp that can firmly clamp the gas seal cover without affecting the machining center's processing of it.

[0004] To achieve the above objectives, one of the technical solutions adopted by this utility model is: a turbocharger gas seal cover clamp, comprising: a circular mounting base; a lower support base, the lower support base being fixed at the center of the circular mounting base, the lower support base having multiple upwardly extending lower support brackets on its circumference, the lower support brackets being used to support the lower circumferential end face of the gas seal cover; and multiple side support bases, the side support bases being provided on the circumference of the upper end face of the circular mounting base, the side support bases being driven by a drive source of a machining center to move back and forth towards or away from the lower support base, the multiple side support bases being able to clamp the circumferential side surface of the gas seal cover.

[0005] The beneficial effects of this utility model's turbocharger air seal cover clamp are as follows: Multiple lower support brackets on the lower support base support the lower circumferential end face of the turbocharger air seal cover. Then, the drive source of the machining center drives multiple side support brackets to move towards the air seal cover, clamping its circumference. This fixes the air seal cover on the clamp. After the machining center processes the center hole, the upper surface of the boss, the upper surface of the large circle, and the groove on the air seal cover, the drive source of the machining center drives the multiple side support brackets to move away from the air seal cover, releasing it. The air seal cover can then be unloaded from the clamp manually or by a robotic arm. This application, by supporting the lower end face of the air seal cover with multiple lower support brackets and then clamping the circumferential side face of the air seal cover locally along its circumference with multiple side support brackets, can stably clamp and fix the air seal cover without affecting the machining center's processing.

[0006] Preferably, the multiple lower support brackets and multiple side support seats are evenly spaced, ensuring that the air seal cover is subjected to uniform force.

[0007] Preferably, each of the lower support brackets is provided with an air hole, the lower end of which is connected to an air supply source. The air hole is also connected to a pressure gauge or pressure sensor. After the air seal cover is clamped, if the position is accurate, the upper surface of the lower support bracket and the lower surface of the air seal cover will be completely in contact, and the pressure gauge or pressure sensor will detect a pressure value within a predetermined range. If the position is inaccurate, a gap will remain between the lower surface of the air seal cover and the lower support bracket, resulting in air pressure leakage. If the pressure gauge or pressure sensor detects a pressure value lower than the predetermined range, it indicates that the air seal cover is not properly placed on the fixture, and the machining center will not start. An alarm may also be triggered to notify the operator. The machining center will only start after the air seal cover is properly installed.

[0008] Preferably, the lower support base has a plurality of first bolt holes at its center for mounting on a circular mounting base.

[0009] Preferably, the side support includes a support block and a limiting block. The limiting block is fixed to the upper surface of the support block and is driven by a drive source from a machining center. The limiting block has an arc surface on its side facing the center of the circular mounting base, and the arc surface matches the shape of the outer circumferential side surface of the gas seal cover. The limiting block can be replaced.

[0010] Preferably, both the upper end face of the support block and the lower end face of the limiting block are provided with rack structures, and the two rack structures mesh with each other; the limiting block is provided with a second bolt hole, and the support block is provided with a strip groove. The limiting block and the support block are locked and fixed by bolts passing through the second bolt hole and the strip groove. In addition to being locked and fixed by bolts, the support block and the limiting block are also fixed by the meshing between the racks, making the connection between the two more secure. The setting of the strip groove allows the position of the limiting block on the support block to be adjusted. When the arc surface of the limiting block is worn, it can be moved forward by one tooth and then locked again.

[0011] Preferably, each of the lower support brackets is bolted with a round pin, and the round mounting base is provided with a round pin hole, the round pin being inserted into and pressed into the round pin hole. Attached Figure Description

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0017] See Figures 1 to 3 As shown, this embodiment discloses a turbocharger gas seal cover clamp, including: a circular mounting base 1; a lower support base 2, the lower support base 2 being fixed to the center of the circular mounting base 1, the lower support base 2 having multiple upwardly extending lower support brackets 3 on its circumference, the lower support brackets 3 being used to support the lower circumferential end face of the gas seal cover 4; and multiple side support bases 5, the side support bases 5 being provided on the circumference of the upper end face of the circular mounting base 1, the side support bases 5 being driven by a drive source of a machining center to move back and forth towards or away from the lower support base 2, the multiple side support bases 5 being able to clamp the circumferential side surface of the gas seal cover 4.

[0018] In this embodiment, there are three lower support brackets 3 and three side support seats 5, which are evenly spaced to ensure that the air seal cover 4 is subjected to uniform force.

[0019] Each of the lower support brackets 3 is provided with an air hole 6, the lower end of which is connected to an air supply source. The air hole 6 is also connected to a pressure gauge or pressure sensor. After the air seal cover 4 is clamped, if the position is accurate, the upper surface of the lower support bracket 3 and the lower surface of the air seal cover 4 will be completely in contact, and the pressure gauge or pressure sensor will detect a pressure value within a predetermined range. If the position is inaccurate, a gap will remain between the lower surface of the air seal cover 4 and the lower support bracket 3, resulting in air pressure leakage. If the pressure gauge or pressure sensor detects a pressure value lower than the predetermined range, it indicates that the air seal cover 4 is not properly placed on the fixture, and the machining center will not start. An alarm may also be triggered to notify the operator. The machining center will only start after the air seal cover 4 is properly installed.

[0020] The lower support 2 has a plurality of first bolt holes 7 at its center for mounting on the circular mounting base 1.

[0021] In this embodiment, the side support 5 includes a support block 5a and a limiting block 5b. The limiting block 5b is fixed to the upper surface of the support block 5a and is driven by a drive source from a machining center. An arc surface 5c is provided on the side of the limiting block 5b facing the center of the circular mounting base 1, and the arc surface 5c matches the shape of the outer circumferential side surface of the gas seal cover 4. The limiting block 5b can be replaced.

[0022] More specifically: both the upper end face of the support block 5a and the lower end face of the limiting block 5b are provided with rack structures 5d, and the two rack structures 5d mesh with each other; the limiting block 5b is provided with a second bolt hole 5e, and the support block 5a is provided with a strip groove 5f. The limiting block 5b and the support block 5a are locked and fixed by bolts passing through the second bolt hole 5e and the strip groove 5f. In addition to being locked and fixed by bolts, the support block 5a and the limiting block 5b are also fixed by the meshing between the racks, making the connection between the two more secure. The setting of the strip groove 5f makes the position of the limiting block 5b on the support block 5a adjustable. When the arc surface 5c of the limiting block 5b is worn, it can be moved forward by one tooth and then locked again.

[0023] In this embodiment, each of the lower support brackets 3 is bolted with a round pin 9 below it, and the round mounting base 1 is provided with a round pin hole 8, and the round pin 9 is inserted into and pressed into the round pin hole 8.

[0024] The working principle of this embodiment is as follows: a person or a robot moves the gas seal cover onto the cover fixture. The three lower support brackets 3 of the lower support base 2 support the lower circumferential end face of the turbocharger gas seal cover 4. Then, the drive source of the machining center drives the three side support bases 5 to move synchronously towards the gas seal cover 4, clamping the circumference of the gas seal cover 4. In this way, the gas seal cover 4 is fixed on the fixture. After the machining center processes the center hole 4a, the upper end face of the boss 4b, the upper end face of the large circle 4c, and the groove 4d of the gas seal cover 4, the drive source of the machining center drives the multiple side support bases 5 to move away from the gas seal cover 4, releasing the gas seal cover 4. The person or a robot then unloads it from the fixture.
