Description

Technical Field

[0001] This utility model relates to the field of servo drives, specifically a modular assembled servo drive. Background Technology

[0002] Servo drives are a crucial component of modern motion control and are widely used in automated equipment such as industrial robots and CNC machining centers. Servo drives for controlling AC permanent magnet synchronous motors, in particular, have become a research hotspot both domestically and internationally. Current AC servo drive designs commonly employ a three-loop control algorithm based on vector control, encompassing current, speed, and position. The rationality of the speed loop design within this algorithm plays a critical role in the overall servo control system, especially in achieving optimal speed control performance.

[0003] Current modular assembly servo drives, as described in patent CN220570770U, include a servo drive body 1, with servo drive bodies 2 on both sides of the servo drive body 1. A mounting base 1 is fixedly mounted at the top and bottom positions of both ends of the servo drive body 1. A locking groove 1 is formed on the side of the mounting base 1 away from the servo drive body 1. A limiting groove is formed inside the mounting base 1 corresponding to the inner wall of the locking groove 1. A connecting seat is fixedly connected to one side of the limiting groove. A suction cup is fixedly mounted on one side of the connecting seat. A locking plate 1 is fixedly mounted at the top and bottom positions of the two servo drive bodies 2 opposite to each other. One side of the locking plate 1 extends into the interior of the locking groove 1 and engages with it.

[0004] Regarding the aforementioned technologies, the inventors believe that by designing a card holder, a card slot, a card plate, a limiting slot, a limiting rod, a suction cup, an adsorption head, a movable slot, a limiting component, a limiting head, and an arc-shaped slot, a structure that allows for quick assembly between two or even three servo drives can be achieved. This makes it convenient for users to assemble multiple servo drives. However, the assembly spacing between two adjacent servo drives is small and cannot be adjusted, resulting in poor heat dissipation of the servo drives after assembly. Utility Model Content

[0005] The purpose of this invention is to provide a modular assembly servo driver to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A modular assembly servo drive, including

[0008] An adjustment mechanism includes a servo driver body. Extension plates are fixedly connected to both sides of the servo driver body. Guide rods slide symmetrically through the interiors of both sets of extension plates. An upper limit block is fixedly connected to one end of each of the two upper sets of guide rods. Upper limit slots are formed on opposite sides of each of the two upper limit blocks. A lower limit block is fixedly connected to one end of each of the two lower sets of guide rods. Lower limit slots are formed on opposite sides of each of the two lower limit blocks. A traction bar is fixedly connected to the other end of each of the two sets of guide rods on the same side. Adjustment screws are threaded into the interiors of each of the two sets of traction bars. One end of each set of adjustment screws is rotatably connected to the two sets of extension plates.

[0009] The connecting mechanism includes symmetrically fixedly connected to the side of the servo driver body away from the upper limit block, and the two sets of the locking strips are respectively adapted to the two sets of upper limit slots and the two sets of lower limit slots.

[0010] As a further embodiment of this utility model: a side plate is fixedly connected to one side of each of the two sets of extension plates, the side plate is fixedly connected to the servo driver body, and waist holes are symmetrically opened on the side of the side plate and the extension plate away from the servo driver body.

[0011] As a further embodiment of this utility model: a reinforcing rib is fixedly connected to one side of both the side plate and the extension plate, and the reinforcing rib is fixedly connected to the main body of the servo driver.

[0012] As a further embodiment of this utility model: the interior of both sets of card strips is symmetrically provided with limiting holes, and each set of limiting holes corresponds to each set of guide rods.

[0013] As a further embodiment of this utility model: a set of guide rods are internally threaded with limit bolts, and the limit bolts extend into the interior of a set of upper limit grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By adopting the above-described structure, this utility model, through the mutual cooperation of the adjusting screw, guide rod, upper limit block, and lower limit block, enables the traction bar to move when the adjusting screw rotates. When the traction bar moves, it can drive the guide rod, upper limit block, and lower limit block to move, thereby adjusting the distance between the upper limit block, lower limit block, and extension plate. This allows the two extension plates to be assembled at different distances after the clip is inserted into the upper limit slot and lower limit slot, leaving a gap between adjacent lower limit blocks to facilitate heat dissipation when the servo driver body is working, thus improving the heat dissipation effect after multiple drivers are assembled.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Please see Figure 1-4 A modular assembled servo drive includes an adjustment mechanism 1, which includes a servo drive body 101. Extension plates 102 are fixedly connected to both sides of the servo drive body 101. Side plates 204 are fixedly connected to one side of each of the two sets of extension plates 102. The side plates 204 are fixedly connected to the servo drive body 101. Waist holes 205 are symmetrically opened on the side of the side plates 204 and the extension plates 102 away from the servo drive body 101. The waist holes 205 are provided for the mounting bolts to pass through when the servo drive body 101 is installed, so as to satisfy the installation and fixation of the servo drive body 101. The side plates 204 and the extension plates 102 can satisfy the installation and fixation of different sides of the servo drive body 101.

[0024] A reinforcing rib 111 is fixedly connected to one side of both the side plate 204 and the extension plate 102. The reinforcing rib 111 is fixedly connected to the servo driver body 101. The reinforcing rib 111 is used to further connect and fix the extension plate 102 and the side plate 204 to the servo driver body 101, thereby improving the connection stability between the extension plate 102 and the side plate 204 and the servo driver body 101. Guide rods 105 are symmetrically slidably passed through the interior of both sets of extension plates 102. One end of each of the two sets of upper guide rods 105 is fixedly connected to an upper limit block 107. Upper limit slots 108 are opened on opposite sides of the two sets of upper limit blocks 107. One end of each of the two sets of lower guide rods 105 is fixedly connected to a lower limit block 109. The guide rods 105 are used to drive the upper limit block 107 or the lower limit block 109 to move when moving.

[0025] Each of the two sets of lower limit blocks 109 has a lower limit groove 110 on its opposite side. The other ends of the two sets of guide rods 105 on the same side are fixedly connected to traction bars 104. Adjusting screws 103 are threaded into the interior of each of the two sets of traction bars 104. One end of each adjusting screw 103 is rotatably connected to the two sets of extension plates 102. The adjusting screws 103 are configured to move the traction bars 104 during rotation, thereby moving the guide rods 105 accordingly. The connecting mechanism 2 includes locking strips 201 symmetrically fixed to the side of the servo drive body 101 away from the upper limit block 107. The two sets of locking strips 201 are adapted to the two sets of upper limit grooves 108 and the two sets of lower limit grooves 110, respectively. The locking strips 201 are configured to connect the two servo drive bodies 101 after being inserted into the upper limit grooves 108 and the lower limit grooves 110.

[0026] Both sets of retaining bars 201 have symmetrically formed limiting holes 202 inside. Each set of limiting holes 202 corresponds to a set of guide rods 105. The limiting holes 202 are designed to allow bolts to pass through during the installation of the servo driver body 101, facilitating the installation of the servo driver body 101 on the side closest to the retaining bar 201. A set of guide rods 105 has internal threaded connections to limiting bolts 203. The limiting bolts 203 extend into the interior of a set of upper limiting grooves 108. The limiting bolts 203 are designed to limit the retaining bar 201 after it is inserted into the upper limiting groove 108 and the lower limiting groove 110 and then screwed into the corresponding limiting hole 202.

[0027] In this embodiment, the servo driver body 101 is existing technology and will not be described in detail here.

[0028] In use, when multiple servo drive bodies 101 need to be assembled, the upper and lower sets of adjusting screws 103 can be rotated according to the required spacing between two adjacent servo drive bodies 101 after assembly. When the adjusting screws 103 are rotated, they can drive the traction bar 104, guide rod 105, upper limit block 107 and lower limit block 109 to move until the spacing between the lower limit block 109 and upper limit block 107 and the extension plate 102 is adjusted to the required size. Then, the two side clips 201 can be inserted into the two upper limit slots 108 and two lower limit slots 110 on the previous drive, thereby realizing the assembly of two sets of drives. After that, the limiting bolt 203 can be rotated so that the limiting bolt 203 is inserted into the inside of a set of limiting holes 202, thereby limiting the clip 201 and completing the assembly of two drives. Then, multiple drives can be assembled and connected in this way.

[0029] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
