Description

Technical Field

[0001] The utility model relates to the field of automation, in particular to a rotary displacement module. Background Art

[0002] In automated production assembly lines, there is often a need to move and rotate workpieces. Currently, a method that combines a linear drive mechanism and a rotary drive mechanism is usually adopted. For example, a rotary cylinder is installed on the sliding part of a linear cylinder to enable the part to rotate while moving.

[0003] However, current rotary drive mechanisms are usually tall and heavy. For smaller workpieces, using a rotary drive mechanism to achieve rotation usually results in a large waste of space, making it difficult to apply to scenarios that require a high level of the mechanism. Utility Model Content

[0004] The utility model aims to provide a rotation displacement module with a relatively small overall height.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] A rotation displacement module, comprising:

[0007] A translation assembly, comprising a driving member, a sliding member and a carrier, wherein a target member to be transferred is carried on the carrier, the carrier is rotatably connected to the sliding member, and the driving member drives the sliding member to controllably move between a first position and a second position;

[0008] The rotating assembly includes a fixed part, a movable part and a connecting rod, wherein the fixed part is arranged on a workbench, and the horizontal position of the fixed part forms a triangle with the first position and the second position, the movable part is rotatably connected to the fixed part and slidably connected to the connecting rod, the connecting rod is connected to the carrier, and the angle between the connecting rod and the carrier in the horizontal direction is a fixed value.

[0009] Optionally, the connecting rod is horizontally arranged, has a first end and a second end opposite to the first end, and the second end of the connecting rod is connected to the carrier.

[0010] Optionally, a limiting member is provided at the first end of the connecting rod, and when the movable member is located at the first end of the connecting rod, the limiting member abuts against the movable member.

[0011] Optionally, the rotating assembly also includes a fastening block and a fastening bolt, the fastening block has a connecting groove and an adjustment hole, the inner wall of the connecting groove abuts against the outer wall of the second end of the connecting rod, the adjustment hole passes through the connecting groove, and the fastening bolt fastens the outer walls of the fastening block on both sides of the connecting groove through the adjustment hole.

[0012] Optionally, the connecting groove includes an adjusting portion and a matching portion connected to each other, the inner wall of the matching portion matches the outer wall of the connecting rod, the adjusting portion connects the matching portion and an edge of the fastening block, and the adjusting hole passes through the matching portion of the connecting groove.

[0013] Optionally, the fastening block and the target component are respectively arranged on opposite sides of the carrier.

[0014] Optionally, the driving member is a rodless cylinder.

[0015] Optionally, the movable part is a linear bearing, and the movable part is sleeved on the outside of the connecting rod.

[0016] Optionally, the carrier includes a horizontally arranged platform and a positioning member supported on the platform, the positioning member includes a plurality of interference blocks, and the plurality of interference blocks surround the target member and all interfere with the target member.

[0017] Optionally, the connecting rod is detachably connected to the carrier, and / or the fixing member is detachably connected to the workbench.

[0018] The beneficial effect of the utility model is that when the carrier moves with the sliding member, the direction of the connecting rod connected between the fixed fixing member and the carrier changes. Since the angle between the carrier and the connecting rod is fixed, and the carrier is rotatably connected to the sliding seat, the direction of the carrier changes, thereby driving the target part carried by the carrier to rotate. Through this structure, the target part can be rotated while the target part moves, and the time required for rotation is equal to the time of movement, that is, the rotation of the target part can be achieved at a faster speed. The two actions of displacement and rotation are achieved with one driving member, and the structure is simple and the cost is low. And since there is no need to superimpose a rotation drive structure on the sliding block, the overall height of the module is low.

[0019] Furthermore, the rotation angle of the target part is related to the angle of the fixing part relative to the first position and the second position, and the horizontal angle between the connecting rod and the carrier. Removably connecting the connecting rod to the carrier and the fixing part to the workbench helps to adjust the rotation angle of the target part.

[0020] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the utility model in conjunction with the accompanying drawings.

DETAILED DESCRIPTION

[0024] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] See also Figure 1The rotation displacement module protected by the utility model application includes a translation component 1 and a rotation component 2. The translation component 1 includes a driving member 11, a sliding member and a carrier 13. The target member to be transferred is carried on the carrier 13, and the carrier 13 is rotatably connected to the sliding member. The driving member 11 is used to drive the sliding member to move controllably between a first position 111 and a second position 112. The rotation component 2 includes a fixed member 21, a movable member 22 and a connecting rod 24. The fixed member 21 and the first position 111 and the second position 112 are located in the same horizontal plane to form a triangle. The movable member 22 is rotatably connected to the fixed member 21 and slidably connected to the connecting rod 24. The connecting rod 24 is connected to the carrier 13 and forms a fixed angle with the carrier 13 in the horizontal direction.

[0029] By rotating the carrier 131 around the limited fulcrum, the angle of the carrier 131 changes, thereby driving the target part to rotate. Only the driving part 11 provides power, which simplifies the overall structure, helps to adjust the height of the module, and saves energy costs in operation and equipment costs in manufacturing. The rotation operation and the translation operation start and complete at the same time, which has a higher operating efficiency.

[0030] Embodiment 1:

[0031] See also Figure 1 The rotation displacement module shown in a preferred embodiment of the present application includes a translation component 1 and a rotation component 2 that are connected to each other.

[0032] The translation assembly 1 includes a driving member 11 , a sliding member and a carrier 13 .

[0033] The driving member 11 is a rodless cylinder installed on the workbench 101, has a high moving speed, and does not need to be equipped with a sliding track. The driving member 11 has a free end 113 that can slide controllably between a first position 111 and a second position 112 along a linear track.

[0034] The sliding member is installed on the top of the free end 113 of the driving member 11, and is a cylindrical tube structure as a whole. One end of the sliding member is fixedly connected to the free end 113 of the driving member 11, and is vertically arranged, and the outer walls of both ends extend outward, so that a hollow truncated cone 121 is formed at each end of the sliding member, thereby improving the stability of the sliding member.

[0035] The carrier 13 includes a carrier 131, a rotating shaft and a positioning member 132. The carrier 131 is configured as a rectangular platform structure, and a cylindrical rotating shaft is connected to the center of the bottom thereof. The rotating shaft is sleeved on the inner side of the sliding member, and the structure is adapted to the sliding member. The rotating shaft has a horizontal rotational freedom relative to the sliding member, and its position in the vertical direction is constrained by the sliding member.

[0036] The bottom of the platform 131 is supported on the round table 121 of the sliding member, which helps the platform 131 to remain horizontal during the rotation process. A positioning member 132 is fixedly installed on the top of the platform 131, which is used to position the target part to be transferred, constrain the position and setting direction of the target part in the horizontal direction, so that the target part rotates with the rotation of the platform 131.

[0037] The positioning member 132 includes a plurality of abutment blocks 1321, which surround the target member, and the structures of the sides of each abutment block 1321 facing the target member are adapted to the outer wall of the target member. When the target member is placed between the abutment blocks 1321, the outer wall of the target member conflicts with each abutment block 1321, so that the target member has only a vertical degree of freedom relative to the carrier 131. The abutment blocks 1321 are also provided with pick-up and placement grooves at positions corresponding to the corners of the target member, which reduces the risk of interference between the abutment blocks 1321 and the corners of the target member, resulting in difficulty in pick-up and placement, and facilitates the pick-up and placement of the target member.

[0038] The rotating assembly 2 includes a fixed part 21, a movable part 22, a connecting rod 24, a fastening block 25, a fastening bolt and a connecting bolt.

[0039] See also Figure 1 and Figure 2 The fixing member 21 is detachably mounted on the workbench 101 by bolts and is away from the driving member 11. The structure is similar to that of the sliding member. A connecting member 23 is rotatably mounted on the top of the vertically arranged fixing member 21. The structure of the connecting member 23 is similar to that of the carrier 131. A movable member 22 is fixedly connected to the top of the carrier 131. In this embodiment, the movable member 22 adopts a linear bearing.

[0040] The connecting rod 24 is a cylindrical rod with a diameter adapted to the movable member 22, and is slidably connected to the movable member 22. The connecting rod 24 has a first end 241 and a second end 242 opposite to each other. The first end 241 of the connecting rod 24 expands to form a cylindrical stopper 243 with a diameter larger than the inner diameter of the movable member 22 to prevent the connecting rod 24 from falling off the movable member 22. The second end 242 of the connecting rod 24 is connected to a fastening block 25.

[0041] The fastening block 25 is a rectangular block structure as a whole, and a connecting groove 251 is provided on one side with a shorter length. The connecting groove 251 includes an adjusting portion 2511 and a matching portion 2512 that are connected to each other. The matching portion 2512 is a through hole whose inner diameter matches the diameter of the connecting rod 24. The adjusting portion 2511 connects the position of the through hole close to the edge of the fastening block 25 with the edge of the fastening block 25 to form a long strip of groove, so that the size of the matching portion 2512 can be easily adjusted. The fastening block 25 is also provided with an adjusting hole 252, which vertically passes through the side wall of the adjusting portion 2511 of the connecting groove 251, and a threaded structure is provided on the inner wall of the adjusting hole 252. The fastening block 25 is mounted on the bottom of the carrier 131. The structure of the fastening bolt matches the adjustment hole 252 of the fastening block 25. The fastening bolt passes through the screw hole on the carrier 131 and the adjustment hole 252 of the fastening block 25, and is fastened with the matching nut, so that the inner wall of the matching portion 2512 of the connecting groove 251 clamps the second end 242 of the connecting rod 24. A fixing hole 253 is also provided on the fastening block 25 on the side away from the adjustment portion 2511 of the matching portion 2512 of the connecting groove 251. The fixing hole 253 is a screw hole parallel to the adjustment hole 252. The connecting bolt matched with the fixing hole 253 passes through the fixing hole 253 to connect the fastening block 25 with the carrier 131, so that the connecting rod 24 and the carrier 131 are relatively fixed, so that the angle between the connecting rod 24 and the carrier 131 remains unchanged, and the connecting rod 24 and the carrier 131 can be easily disassembled.

[0042] When the sliding member is driven by the driving member 11 to translate, the relative position of the sliding member and the fixing member 21 changes, and the angle between the connecting rod 24 and the sliding member changes because the connecting rod 24 is connected between the sliding member and the fixing member 21. The carrier 13 is rotationally connected to the sliding member, and the angle between the carrier 13 and the connecting rod 24 remains unchanged, causing the carrier 13 to drive the target member carried therein to rotate.

[0043] The target part is driven to translate and rotate simultaneously only by the driving part 11, which simplifies the structure of the module, significantly reduces its minimum height, reduces the mechanical cost during manufacturing and the energy cost during use, and the translation and rotation of the target part are completed simultaneously, and can be completed in a shorter time, with higher operating efficiency.

[0044] Embodiment 2:

[0045] The only difference between this embodiment and the first embodiment is that the limiting member 243 is not provided on the connecting rod 24 in this embodiment, so as to facilitate the installation and disassembly of the connecting rod 24 .

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
