Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone rear shell processing, in particular to a special clamp for rear shell processing with an anti-deviating function. Background Art

[0002] The back shell of a mobile phone is an important component of the mobile phone. During the processing of the back shell of the mobile phone, in order to ensure that the position of the back shell is fixed during the processing and maintain accurate positioning to improve the processing accuracy, a special clamp is needed to fix it.

[0003] The Chinese patent "A special fixture for processing the back shell of a mobile phone" authorization announcement number "CN 213258189 U" drives the reduction box to rotate through the output end of the motor, so that the second gear drives the threaded rod to rotate, and the threaded sleeve is driven to move left and right by the threaded rod, so that the sliding sleeve drives the vertical rod to move left and right, and the vertical rod drives the clamping plate and the anti-skid pad to move left and right, and the mobile phone back shell is fixed by the clamping plate and the anti-skid pad, thereby achieving the purpose of easy fixation, improving the practicality and practicability of the special fixture for processing the back shell of the mobile phone, and solving the problem of inconvenient fixation of the special fixture for processing the back shell of the mobile phone in the past.

[0004] In the above scheme, the mobile phone back cover can be fixed by two clamps, but the clamping force of the clamps on the mobile phone back cover cannot be guaranteed during the moving and clamping process, and excessive clamping is easy to cause deformation of the back cover, affecting the quality of the back cover.

[0005] Therefore, a special fixture for processing a rear shell with an anti-deviating function is proposed to solve the above problem. Utility Model Content

[0006] The purpose of the utility model is to provide a special clamp for back shell processing with an anti-drift function in order to solve the above-mentioned problem, thereby improving the problem that the clamping force of the clamp on the back shell of the mobile phone cannot be guaranteed during the moving clamping process, and it is easy to over-clamp, resulting in deformation of the back shell and affecting the quality of the back shell.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a special clamp for processing a back shell with an anti-drift function, comprising: a base, a fixing mechanism is arranged on the top of the base; wherein the fixing mechanism comprises a supporting plate fixedly connected to the middle part of the top of the base, two movable plates are slidably connected to the top of the base, the inner wall of the movable plate is fixedly connected to a cylinder, the inner wall of the cylinder is slidably connected to a piston rod, a spring is fixedly connected between one end of the piston rod and the inner wall of the cylinder, the other end of the piston rod passes through the cylinder and is fixedly connected to the fixing plate, one end of the cylinder is fixedly connected to an air inlet pipe, the upper surface of the cylinder is fixedly connected to an air outlet pipe, and the top of the air outlet pipe is provided with a cover plate.

[0008] Preferably, the fixing mechanism further comprises a bidirectional screw rotatably connected to the inner wall of the base, a slider is threadedly connected to the surface of the bidirectional screw, and the top of the slider is fixedly connected to the bottom of the corresponding movable plate, which is conducive to enabling the two movable plates to drive the corresponding fixed plates to move synchronously to fix the rear shell.

[0009] Preferably, a circular ring is fixedly connected to the surface of the cover plate, and a ribbon distributed in a circular shape is fixedly connected to the bottom end of the circular ring. By observing whether the ribbon swings, it is helpful for the staff to better observe whether there is gas discharged from the outlet pipe. When the ribbon swings, it is helpful for the staff to promptly notify the rotation of the bidirectional screw rod, so that the staff can better control the moving distance of the fixed plate.

[0010] Preferably, a one-way valve is installed on the surface of the air intake pipe, which ensures one-way air intake in the air intake pipe and prevents gas from being discharged from the air intake pipe.

[0011] Preferably, a contact pad is fixedly connected to the other side of the fixing plate, and the contact pad is a rubber component, and the surface of the contact pad is provided with grooves distributed in equal rows, so as to avoid the fixing plate from causing wear to the rear shell, and at the same time increase the friction between the fixing plate and the rear shell when fixing.

[0012] Preferably, the cover plate is a foam member, which reduces the resistance when the gas blows the cover plate.

[0013] Preferably, the upper end of the inner wall of the air outlet pipe is fixedly connected with a limit rod, the top end of the limit rod passes through the cover plate, and the inner wall of the cover plate is slidably connected to the surface of the limit rod. This is conducive to limiting the movement of the cover plate and ensuring that the cover plate is in a blocking state on the top end of the air outlet pipe when the device is in the initial state.

[0014] Preferably, the bottom end of the fixing plate is fixedly connected with a reinforcing plate, and the top end of the reinforcing plate is on the same horizontal plane as the top end of the supporting plate. When the rear shell is processed, it is beneficial to provide a certain support from the bottom of the rear shell, thereby enhancing the stability of the rear shell when it is fixed.

[0015] The beneficial effects of the utility model are:

[0016] 1. When fixing the back shell of the mobile phone, the support plate is used to initially support the back shell, and under the action of the spring and the piston rod, it is helpful to ensure that the fixing plate can move in the opposite direction for a certain distance, so as to avoid the fixing plate from excessively moving and squeezing the back shell when fixing the back shell, and under the action of the air outlet pipe, when the fixing plate moves in the opposite direction under pressure, it is helpful to discharge the excess gas in the cylinder through the air outlet pipe, so as to ensure that the fixing plate always maintains a constant clamping force when fixing the back shell, so as to avoid deformation of the back shell when fixing, thereby ensuring the quality of the back shell;

[0017] 2. By observing whether the ribbon is swinging, it is helpful for the staff to better observe whether there is gas discharged from the outlet pipe. The swing of the ribbon is helpful for the staff to promptly notify the rotation of the bidirectional screw rod, so that the staff can better control the moving distance of the fixed plate.

DETAILED DESCRIPTION

[0024] 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.

[0025] When implementing: Figure 1-5As shown, a special fixture for processing a rear shell with an anti-deviating function comprises: a base 1, a fixing mechanism 2 is arranged at the top of the base 1; wherein the fixing mechanism 2 comprises a supporting plate 218 fixedly connected to the middle part of the top of the base 1, two movable plates 21 are slidably connected to the top of the base 1, a cylinder 22 is fixedly connected to the inner wall of the movable plate 21, a piston rod 24 is slidably connected to the inner wall of the cylinder 22, a spring 23 is fixedly connected between one end of the piston rod 24 and the inner wall of the cylinder 22, the other end of the piston rod 24 passes through the cylinder 22 and is fixedly connected to a fixing plate 25, an air inlet pipe 27 is fixedly connected to one end of the cylinder 22, an air outlet pipe 26 is fixedly connected to the upper surface of the cylinder 22, and a cover plate 28 is arranged at the top of the air outlet pipe 26.

[0026] When the device is in an initial state, under the action of the spring 23 , external gas will enter the cylinder 22 through the air inlet pipe 27 and press the piston rod 24 .

[0027] like Figure 2 As shown, the fixing mechanism 2 also includes a bidirectional screw rod 29 rotatably connected to the inner wall of the base 1 , a slider 210 is threadedly connected to the surface of the bidirectional screw rod 29 , and the top end of the slider 210 is fixedly connected to the bottom end of the corresponding movable plate 21 .

[0028] When fixing the back shell of the mobile phone, the back shell is placed on the support plate 218, and the bidirectional screw 29 is rotated to drive the two movable plates 21 to move synchronously and approach each other through the two sliders 210, so that the two movable plates 21 drive the two fixed plates 25 to move synchronously and approach each other to fix the back shell. When the fixed plate 25 completes the fixation of the back shell during the movement, at this time, under the interaction of the back shell and the movable plate 21, the back shell will reversely squeeze the fixed plate 25, so that the fixed plate 25 drives the piston rod 24 to move in the opposite direction and squeeze the gas in the cylinder 22, and the spring 23 is compressed. When the gas in the cylinder 22 is squeezed, it will enter the air outlet pipe 26 and push the cover plate 28 to move upward to form a gap between the bottom end of the cover plate 28 and the top end of the air outlet pipe 26. At this time, the gas will be discharged through the gap.

[0029] like Figure 4 As shown, a ring 212 is fixedly connected to the surface of the cover plate 28, and a ribbon 213 distributed in a ring shape is fixedly connected to the bottom end of the ring 212. When the gas is discharged through the gap between the bottom end of the cover plate 28 and the top end of the gas outlet pipe 26, the ribbon 213 is blown to swing. When the staff observes the swing of the ribbon 213, the rotation of the bidirectional screw rod 29 is stopped, and at this time, the rear shell is fixed.

[0030] like Figure 3 As shown, a one-way valve 211 is installed on the surface of the air intake pipe 27. Under the action of the one-way valve 211, the air intake pipe 27 can only take in air in one direction.

[0031] like Figure 5 As shown, a contact pad 214 is fixedly connected to the other side of the fixing plate 25. The contact pad 214 is a rubber component, and the surface of the contact pad 214 is provided with grooves 215 distributed in equal rows. When the fixing plate 25 fixes the rear shell, the surface of the contact pad 214 contacts the surface of the rear shell.

[0032] like Figure 3 and Figure 4 As shown, the cover plate 28 is a foam member. The weight is relatively light, and the resistance to the gas blowing cover plate 28 moving upward is small.

[0033] like Figure 3 As shown, the upper end of the inner wall of the gas outlet pipe 26 is fixedly connected to a limit rod 217, the top end of the limit rod 217 passes through the cover plate 28, and the inner wall of the cover plate 28 is slidably connected to the surface of the limit rod 217. When the cover plate 28 is blown upward by the gas, the inner wall of the cover plate 28 slides along the surface of the limit rod 217.

[0034] like Figure 5 As shown, the bottom end of the fixing plate 25 is fixedly connected with a reinforcing plate 216, and the top of the reinforcing plate 216 is on the same horizontal plane as the top of the supporting plate 218. When the fixing plate 25 moves to fix the rear shell, the reinforcing plate 216 will first enter the bottom of the rear shell and contact the bottom end of the rear shell.

[0035] When the utility model is used, when fixing the back shell of the mobile phone, the back shell is placed on the support plate 218, and the bidirectional screw rod 29 is rotated, and the two sliders 210 drive the two moving plates 21 to move synchronously and approach each other, so that the two moving plates 21 drive the two fixed plates 25 to move synchronously and approach each other to fix the back shell. In the process of the movement of the fixed plate 25, the reinforcement plate 216 will first enter the bottom of the back shell and contact with the bottom end of the back shell. At this time, the fixed plate 25 continues to move. When the contact pad 214 on the other side of the fixed plate 25 contacts the surface of the back shell, at this time, the bidirectional screw rod 29 is slowly rotated, so that the moving plate 21 drives the fixed plate 25 to move slowly. The rear shell is pressed tightly, and when the fixed plate 25 completes the fixation of the rear shell during the movement, at this time, under the interaction of the rear shell and the movable plate 21, the rear shell will reversely squeeze the fixed plate 25, so that the fixed plate 25 drives the piston rod 24 to move in the opposite direction and squeeze the gas in the cylinder 22, and the spring 23 is compressed. When the gas in the cylinder 22 is squeezed, it will enter the air outlet pipe 26 and push the cover plate 28 to move upward to create a gap between the bottom end of the cover plate 28 and the top end of the air outlet pipe 26. At this time, the gas will be discharged through the gap and blow the ribbon 213 to swing. When the staff observes the swing of the ribbon 213, they stop rotating the bidirectional screw 29. At this time, the constant pressure fixation of the rear shell is completed.

[0036] 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.
