Description

Technical Field

[0001] The utility model relates to the field of assembly fixtures, in particular to an assembly fixture for assembling communication equipment modules which can accurately position. Background Art

[0002] Communication modules are widely used in vehicle monitoring, remote control, telemetry, small wireless networks, wireless meter reading, access control systems, community paging, industrial data acquisition systems, wireless tags, identity recognition, contactless RF smart cards, small wireless data terminals, security and fire protection systems, wireless remote control systems, biological signal acquisition, hydrological and meteorological monitoring, robot control, digital audio, digital image transmission and other fields. In the assembly and production of communication equipment, they are fixed by positioning fixtures, making it easy to install the electrical components in the communication equipment.

[0003] After searching, the Chinese patent "A positioning fixture for assembling electronic equipment" with the authorization announcement number "CN215358162U" is found. According to the position of the electronic components of the electronic equipment, the pull-out cover is pulled so that the push plate contracts the elastic spring under force, and one end of the assembly rod is taken out of the assembly hole and can be appropriately moved on the sliding groove through the slider. Then, by loosening the pull-out cover, the reaction force generated by the elastic spring causes the push plate to push the assembly rod to assemble the assembly hole, so that the slider is fixed to the bottom plate. At the same time, the operating block can be rotated on the connecting column, and the direction of the operating block is changed. The first rotating cover and the second rotating cover are rotated to adjust the first operating rod and the second operating rod respectively, so that the pad clamps the electronic device.

[0004] Although the patented technology solves the problem that the existing positioning fixture cannot be adjusted according to the on-site installation environment of the electronic components during the clamping process, making the positioning fixture not flexible enough during the clamping process and affecting the assembly efficiency of the electronic components of the electronic equipment, the patented technology requires manual adjustment of the clamping force when clamping the device, and it is impossible for humans to observe with the naked eye whether the clamping force is appropriate. Therefore, an assembly fixture for assembling communication equipment modules that can accurately position is proposed to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide an assembly fixture for assembling communication equipment modules that can accurately position in order to solve the above problems, thereby improving the problem that the clamping force needs to be adjusted manually while the human eye cannot observe whether the clamping force is appropriate.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: an assembly fixture for assembling a communication equipment module capable of precise positioning, comprising an assembly table; a clamping component, wherein the clamping component comprises a first motor installed on one side of the assembly table, the output end of the first motor is fixedly connected with a positive and negative threaded screw rod, a clamping plate is arranged outside the positive and negative threaded screw rod, a pressure sensor is arranged inside the clamping plate, a spring damper fixed on the surface of the pressure sensor is arranged inside the clamping plate, and a clamping block is slidably connected inside the clamping plate.

[0007] Preferably, the forward and reverse screw rods are rotatably connected in the assembly table via bearings, the number of the clamping plates is two and they are symmetrically distributed, and the clamping block is fixedly connected to one end of the spring damper.

[0008] Preferably, two symmetrically distributed pull rods are fixedly connected inside the clamp, and one side of the clamp block is fixed to the pull rod. When the clamping position of the communication equipment is not accurate enough, fixing the clamp block only by spring damping will cause the clamp block to tilt, resulting in an error in the pressure value sensed by the pressure sensor. At this time, the set pull rod can limit the clamp, so that the force on the surface of the clamp block can be accurately transmitted to the pressure sensor.

[0009] Preferably, a slide rod is fixedly connected inside the assembly table, and the clamping plate is slidably connected to the surface of the slide rod.

[0010] Preferably, a bearing base is provided at the bottom of the assembly table, and a second motor is embedded and installed in the bearing base.

[0011] Preferably, the output end of the second motor is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected in the supporting base via a bearing.

[0012] Preferably, a rotating disk is fixedly connected to the top end of the rotating shaft, and the rotating disk is fixedly connected to the bottom of the assembly table.

[0013] Preferably, four symmetrically distributed support legs are fixedly connected to the bottom of the bearing base.

[0014] The beneficial effects of the utility model are:

[0015] 1. The first motor drives the positive and negative screws to rotate, thereby driving the two clamps to move. When the clamps touch the communication equipment, the spring damping force contracts. At the same time, the pressure sensor converts the pressure into an electrical signal. When the predetermined pressure value is reached, the pressure sensor controls the first motor to stop working through the electrical signal, which can prevent the problem of excessive clamping force on the communication equipment.

[0016] 2. The pull rod can limit the clamp plate to prevent the clamp block from tilting, so that the force on the surface of the clamp block can be accurately transmitted to the pressure sensor. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] When implementing: Figure 1-4 As shown, an assembly fixture for assembling a communication device module capable of precise positioning comprises an assembly table 1; a clamping component 2, the clamping component 2 comprises a first motor 21 installed on one side of the assembly table 1, the output end of the first motor 21 is fixedly connected with a positive and negative threaded rod 22, a clamping plate 23 is arranged outside the positive and negative threaded rod 22, a pressure sensor 24 is arranged inside the clamping plate 23, a spring damper 25 fixed on the surface of the pressure sensor 24 is arranged inside the clamping plate 23, a clamping block 26 is slidably connected inside the clamping plate 23, through the positive and negative threaded rod 22, when the device needs to be clamped, the positive and negative threaded rod 22 will be driven to rotate by the first motor 21, and the two clamping plates 23 installed outside the positive and negative threaded rod 22 will move in the positive and negative directions respectively, so as to clamp or release the communication device.

[0024] like Figure 3 and Figure 4As shown, the positive and negative threaded rods 22 are rotatably connected in the assembly table 1 via bearings, there are two clamping plates 23 which are symmetrically distributed, and the clamping block 26 is fixedly connected to one end of the spring damper 25 .

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, two symmetrically distributed pull rods 3 are fixedly connected inside the splint 23, one side of the clamping block 26 is fixed to the pull rod 3, and a sliding rod 4 is fixedly connected inside the assembly table 1. The splint 23 is slidably connected to the surface of the sliding rod 4. When the device needs to be clamped, the first motor 21 will drive the positive and negative screw rods 22 to rotate, thereby driving the two splints 23 to move. The sliding rod 4 can be set to limit the moving splint 23 to prevent the splint 23 from rotating with the rotating positive and negative screw rods 22.

[0026] like Figure 1 and Figure 2 As shown, a supporting base 5 is provided at the bottom of the assembly table 1, and a second motor 6 is embedded in the supporting base 5. The output end of the second motor 6 is fixedly connected to a rotating shaft 7, and the rotating shaft 7 is rotatably connected in the supporting base 5 through a bearing. The top of the rotating shaft 7 is fixedly connected to a rotating disk 8, and the rotating disk 8 is fixedly connected to the bottom of the assembly table 1. Four supporting legs 9 are fixedly connected to the bottom of the supporting base 5 and are symmetrically distributed.

[0027] When the utility model is in use, the first motor 21 is used to drive the forward and reverse screw rods 22 to rotate, thereby driving the two clamping plates 23 to move. When the clamping plates 23 touch the communication equipment, the spring damping 25 is forced to contract. At the same time, the pressure sensor 24 converts the pressure into an electrical signal. When the predetermined pressure value is reached, the pressure sensor 24 controls the first motor 21 to stop working through the electrical signal. At this time, the clamping work of the communication equipment can be completed.

[0028] When the clamping assembly 2 needs to be rotated, the second motor 6 drives the rotating shaft 7 to rotate, and the rotating rotating shaft 7 drives the clamping assembly 2 on the top of the assembly table 1 to rotate through the rotating disk 8.

[0029] It should be noted that the first motor 21, pressure sensor 24, spring damper 25, second motor 6 and rotating disk 8 in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs. At the same time, the power supply of the first motor 21, the pressure sensor 24 and the second motor 6 can be a built-in power supply or a mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
