Description

Technical Field

[0001] The utility model relates to the technical field of motor drivers, in particular to a small-power linear motor servo driver. Background Technique

[0002] The linear module motor is also called a linear motor. The most commonly used types of linear motors are flat, U-groove and tubular. The control of a linear motor is the same as that of a rotary motor. Like a brushless rotary motor, there is no mechanical connection between the mover and the stator. Different from the rotary motor, where the mover rotates and the stator position remains fixed, a linear motor system can be either a moving magnetic track or a moving thrust coil (in most positioning system applications, the magnetic track is fixed and the thrust coil moves).

[0003] During the assembly process of the linear motor, a high-voltage plug is inserted into the power interface of the linear motor driver. After the assembly is completed, the linear motor driver is powered on, and then JOG debugging is carried out to check whether the system is normal. The high-voltage plug is directly inserted into the power interface of the linear motor driver and relies on friction for clamping, or uses a buckle for clamping. While ensuring the stability of the high-voltage plug and the power interface of the linear motor driver, it makes disassembly laborious and the disassembly and assembly are not convenient enough; most linear motor drivers are installed at a specified position through bolts, and multiple bolts need to be removed with a screwdriver during the overhaul and maintenance process, resulting in low installation and disassembly efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a small-power linear motor servo driver to solve the problems raised in the above background technique that the high-voltage plug is directly inserted into the power interface of the linear motor driver, relying on friction for clamping, or using a buckle for clamping. While ensuring the stability of the high-voltage plug and the power interface of the linear motor driver, it makes disassembly laborious and the disassembly and assembly are not convenient enough; most linear motor drivers are installed at a specified position through bolts, and multiple bolts need to be removed with a screwdriver during the overhaul and maintenance process, resulting in low installation and disassembly efficiency.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A small-power linear motor servo driver, including a driver body, a plug connector is fixedly connected to the side wall of the driver body, an operation panel is fixedly arranged on the side wall of the driver body, two mounting frames are symmetrically and fixedly sleeved on the driver body, two insertion rods are symmetrically and fixedly connected to the side wall of the driver body, a U-shaped seat is fixedly connected between the ends of the two insertion rods, an embedding groove is opened inside the U-shaped seat, a high-voltage plug is clamped in the embedding groove, a limiting shell is slidably sleeved outside both insertion rods, a limiting hole is opened on the insertion rod, a clamping block is slidably clamped in the limiting hole, and a sleeve fixedly connected to the driver body is slidably sleeved outside the clamping block.

[0007] Furthermore, two connecting seats are symmetrically and fixedly connected to the ends of the U-shaped seat. A push plate is rotatably connected between the two connecting seats, and a torsion spring is fixedly connected to the connection between the push plate and the connecting seat.

[0008] Furthermore, one end of a connecting rope is fixedly connected to the end of the clamping block. The other end of the connecting rope is fixedly connected to a winding wheel rotatably connected to the driver body. A rotating seat is fixedly sleeved at the central position of the winding wheel, and a return spring fixedly connected to the clamping block is sleeved outside the connecting rope.

[0009] Furthermore, a plurality of heat dissipation strips are fixedly connected to the top and bottom of the driver body at equal distances.

[0010] Furthermore, a mounting seat is fixedly connected to the top of the driver body. A connecting plate is buckled in the mounting seat. Two mounting parts are symmetrically and fixedly connected to the end of the connecting plate. A sliding hole is formed in the mounting seat, and an L-shaped block inserted into the connecting plate is arranged in the sliding hole. A push rod is fixedly connected to the side wall of the L-shaped block.

[0011] Furthermore, a limiting sleeve slidably sleeved with the push rod is fixedly connected in the mounting seat, and a compression spring is fixedly sleeved outside the push rod.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By externally sliding and clamping a U-shaped seat on the strong electric plug, during installation, the two plug rods on the back of the U-shaped seat can be inserted into the limiting shell. During the forward movement of the plug rods, their ends will push the clamping block to slide in the sleeve. When the plug rods are completely inserted, the clamping block will rebound and be embedded into the limiting hole under the action of the return spring. At this time, the U-shaped seat plays an effect of strengthening the positioning of the strong electric plug, avoiding the situation that the strong electric plug is separated from the driver due to being knocked. When disassembling the strong electric plug, the rotating seat drives the winding wheel to wind the two connecting ropes. The ends of the connecting ropes will drive the clamping block to retract into the sleeve, and then the push plate is rotated by 90 degrees. The push plate can be used to push the U-shaped seat, so that the strong electric plug can be quickly separated from the driver body, and it is more labor-saving to disassemble the strong electric plug.

[0014] By pushing the push rod, the L-shaped block can be driven to slide into the sliding hole, and then the connecting plate can be slid and snapped into the mounting seat. The connecting plate and the mounting seat are engaged with each other. Then, after releasing the push rod, the compression spring drives the L-shaped block to insert into the connecting plate, so as to facilitate the limiting of the connecting plate. The mounting parts at the end of the connecting plate can be used for installing the linear motor driver, so the linear motor driver can be quickly installed. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a low-power linear motor servo driver includes a driver body 101. A plug connector 104 is fixedly connected to the side wall of the driver body 101. An operation panel 105 is fixedly arranged on the side wall of the driver body 101. Two mounting frames 103 are symmetrically and fixedly sleeved on the driver body 101. Two plug rods 205 are symmetrically and fixedly connected to the side wall of the driver body 101. A C-shaped seat 201 is fixedly connected between the ends of the two plug rods 205. An embedding groove 204 is formed inside the C-shaped seat 201. A high-power plug 106 is clamped in the embedding groove 204. Limiting shells 207 are slidably sleeved on the outside of the two plug rods 205. Limiting holes 206 are formed in the plug rods 205. Clamping blocks 208 are slidably clamped in the limiting holes 206. Sleeves 209 fixedly connected to the driver body 101 are slidably sleeved on the outside of the clamping blocks 208; A plurality of heat dissipation strips 102 are evenly and fixedly connected to the top and bottom of the driver body 101.

[0022] Specifically, a U-shaped seat 201 is slidably clamped outside the strong electric plug 106. During installation, two insertion rods 205 on the back of the U-shaped seat 201 can be inserted into the limit shell 207. During the forward movement of the insertion rods 205, the end thereof will push the clamping block 208 to slide in the sleeve 209. When the insertion rods 205 are completely inserted, the clamping block 208 will rebound under the action of the return spring 213 and be embedded into the limit hole 206. At this time, the U-shaped seat 201 plays an effect of strengthening the positioning of the strong electric plug 106, avoiding the situation that the strong electric plug 106 is separated from the driver due to being bumped. When disassembling the strong electric plug 106, the winding wheel 211 is driven by the rotating seat 212 to wind the two connecting ropes 210. The end of the connecting rope 210 will drive the clamping block 208 to retract into the sleeve 209, and then the pushing plate 203 is rotated by ninety degrees. The pushing plate 203 can be used to push the U-shaped seat 201, so that the strong electric plug 106 can be quickly separated from the driver body 101, and it is more labor-saving to disassemble the strong electric plug 106. Embodiment 1

[0023] As Figure 2-3 shown, in this embodiment, two connecting seats 202 are symmetrically and fixedly connected to the end of the U-shaped seat 201. A pushing plate 203 is rotatably connected between the two connecting seats 202, and a torsion spring is fixedly connected to the connection between the pushing plate 203 and the connecting seat 202; a sleeve 209 fixedly connected to the driver body 101 is slidably sleeved outside the clamping block 208. One end of a connecting rope 210 is fixedly connected to the end of the clamping block 208, and the other end of the connecting rope 210 is fixedly connected to a winding wheel 211 rotatably connected to the driver body 101. A rotating seat 212 is fixedly sleeved at the central position of the winding wheel 211, and a return spring 213 fixedly connected to the clamping block 208 is sleeved outside the connecting rope 210.

[0024] In this embodiment, the torsion spring connected between the two connecting seats 202 can drive the pushing plate 203 to rotate in the reverse direction and fit with the side wall of the U-shaped seat 201. When the rotating seat 212 can drive the winding wheel 211 to rotate, the winding wheel 211 can wind one end of the connecting rope 210, and then the other end of the connecting rope 210 will drive the clamping block 208 to move away from the limit hole 206, so that the insertion rod 205 cannot be limited, making it convenient for the U-shaped seat 201 to separate the strong electric plug 106. Embodiment 2

[0025] As Figure 4As shown, in this embodiment, a mounting seat 301 is fixedly connected to the top of the driver body 101, a connecting plate 307 is buckled in the mounting seat 301, two mounting members 308 are symmetrically fixedly connected to the ends of the connecting plate 307, a sliding hole 302 is opened in the mounting seat 301, an L-shaped block 306 plugged into the connecting plate 307 is provided in the sliding hole 302, a push rod 304 is fixedly connected to the side wall of the L-shaped block 306; a limiting sleeve 303 slidably sleeved with the push rod 304 is fixedly connected in the mounting seat 301, and an extrusion spring 305 is fixedly sleeved on the outside of the push rod 304.

[0026] During specific implementation, by pushing the push rod 304, the L-shaped block 306 can be driven to slide into the sliding hole 302, and then the connecting plate 307 can be slid and inserted into the mounting seat 301. The connecting plate 307 and the mounting seat 301 are engaged with each other. Then, after releasing the push rod 304, the spring 305 is squeezed to drive the L-shaped block 306 to be inserted into the connecting plate 307, thereby facilitating the limiting of the connecting plate 307. The mounting piece 308 at the end of the connecting plate 307 can be used for the installation of the linear motor driver, so the linear motor driver can be quickly installed.
