Description

Technical Field

[0001] The utility model relates to the field of automated processing, and in particular to a negative pressure adsorption fixture and a clamping module capable of realizing multi-angle operation. Background Art

[0002] With the gradual increase in labor costs, production and processing automation is an inevitable trend. At present, the automation of processing modules has become more and more mature, such as general-purpose CNC machining centers and various special-purpose machine tools. In order to improve processing efficiency and adapt to the processing of complex parts, the application of multi-station processing equipment is becoming more and more extensive. For example, the Chinese invention patent with the authorization announcement number CN 115592474B submitted by the applicant discloses a multi-station processing equipment and processing method. By rotating the fixture seat, the conversion between multiple stations can be realized to complete each processing process, which has the advantage of high production efficiency.

[0003] However, due to the variety of product types, it is difficult to standardize the automated loading operation of product blanks. The irregular cross-section products targeted by this application refer to product blanks that are uniform in the axial direction and shaped in the circumferential direction, such as Figure 1 and Figure 2 The figure shows a type of irregular cross-section product, where 01 is the cross section and 02 is the side. It can be an independent casting blank or cut from a long bar. For product blanks with irregular cross sections, there is a common problem of uncertain orientation during the feeding process, which poses a great challenge to the automation of blank clamping. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a negative pressure adsorption clamp and a clamping module capable of realizing multi-angle operation, which can realize multi-angle clamping and has the advantages of simple structure and reliable clamping.

[0007] The negative pressure chuck clamps the blank in the form of negative pressure adsorbing the blank cross section, and indexes it under the drive of the indexing robot. Since the posture of the blank is uncertain, an auxiliary pallet is set. During the clamping process of the indexing fixture, when the blank cross section is upward, the auxiliary pallet is in the second position state, and the negative pressure chuck works independently in an upright position, so that the upward cross section of the blank can be reliably clamped. When the blank cross section is facing one side, the auxiliary pallet is in the first position state, the auxiliary pallet contacts one cross section of the blank, and the negative pressure chuck adsorbs the other cross section of the blank, and the two cooperate to reliably clamp the cross section of the blank. After the negative pressure chuck is reliably clamped, the auxiliary pallet is separated from the blank cross section to leave space for the indexing of the blank.

[0008] The negative pressure adsorption clamp and clamping module of the present application can achieve multi-angle clamping and have the advantages of simple structure and reliable clamping.

[0009] Preferably, the indexing fixture comprises an indexing mounting seat, on which a first mounting surface and a second mounting surface are provided, and the first mounting surface and the second mounting surface are arranged opposite to each other; the negative pressure chuck is arranged on the first mounting surface; and the auxiliary driving member is arranged on the second mounting surface.

[0010] Preferably, the transfer mounting seat is provided with an operating channel, the auxiliary support plate corresponds to the operating channel, and the operating channel is arranged in a long strip shape;

[0011] In the first position state, the auxiliary support plate passes through the operating channel, and in the second position state, the auxiliary support plate is located in the operating channel or retreats along the operating channel to the side of the second installation surface.

[0012] Preferably, the auxiliary driving member includes a transverse driving member and a longitudinal driving member, and the transverse driving member and the longitudinal driving member cooperate to drive the auxiliary pallet to move.

[0013] A clamping module capable of realizing multi-angle operation includes the negative pressure adsorption clamp as described above, and also includes a visual detection component, wherein the visual detection component is connected to the indexing clamp and moves synchronously; the detection direction of the visual detection component is consistent with the direction of the negative pressure chuck.

[0015] Preferably, the visual detection component includes a camera and a light source. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Example

[0024] like Figure 3-Figure 7 As shown, a negative pressure adsorption clamp capable of realizing multi-angle operation includes a transfer robot 1 and a transfer clamp 2, wherein the transfer clamp 2 includes a negative pressure chuck 23 and an auxiliary clamping assembly, wherein the auxiliary clamping assembly includes an auxiliary support plate 222 and an auxiliary driving member 221, and the auxiliary driving member 221 is used to drive the auxiliary support plate 222 to move.

[0025] The auxiliary support plate 222 has at least two positions: Figure 7 As shown, in the first position state, the auxiliary support plate 222 is arranged opposite to the negative pressure chuck 23; Figure 6 As shown, in the second position state, the auxiliary support plate 222 is misaligned with the negative pressure chuck 23, and the auxiliary support plate 222 is not set lower than the negative pressure chuck 23.

[0026] like Figure 3-Figure 7As shown, specifically, the transfer fixture 2 includes a transfer mounting seat 21, and the transfer mounting seat 21 is provided with a first mounting surface and a second mounting surface, and the first mounting surface and the second mounting surface are arranged opposite to each other. The negative pressure chuck 23 is arranged on the first mounting surface. The auxiliary driving member 221 is arranged on the second mounting surface. The transfer mounting seat 21 is provided with an operating channel, and the auxiliary support plate 222 corresponds to the operating channel, and the operating channel is arranged in a long strip shape. In the first position state, the auxiliary support plate 222 passes through the operating channel, and in the second position state, the auxiliary support plate 222 is located in the operating channel or retreats along the operating channel to the side of the second mounting surface.

[0027] like Figure 5 As shown, specifically, the auxiliary driving member 221 includes a transverse driving member 2212 and a longitudinal driving member 2211 , and the transverse driving member 2212 and the longitudinal driving member 2211 cooperate to drive the auxiliary support plate 222 to move.

[0028] The negative pressure chuck 23 clamps the blank in the form of negative pressure adsorbing the blank cross section, and is indexed under the drive of the indexing robot 1. Since the posture of the blank is uncertain, an auxiliary support plate 222 is set. During the clamping process of the indexing fixture 2, when the cross section of the blank is upward, the auxiliary support plate 222 is in the second position state, and the negative pressure chuck 23 works independently in an upright position, so that the upward cross section of the blank can be reliably clamped. When the cross section of the blank is facing one side, the auxiliary support plate 222 is in the first position state, the auxiliary support plate 222 contacts one cross section of the blank, and the negative pressure chuck 23 adsorbs the other cross section of the blank, and the two cooperate to reliably clamp the cross section of the blank. After the negative pressure chuck 23 reliably clamps, the auxiliary support plate 222 separates from the cross section of the blank to leave space for the indexing of the blank.

[0029] The negative pressure adsorption clamp and clamping module of the present application can achieve multi-angle clamping and have the advantages of simple structure and reliable clamping.
