A weighing instrument manufacturing and processing adjustment mechanism

Abstract

This utility model discloses an adjustment mechanism for processing in the manufacture of weighing instruments, including a clamping platform, a support plate, and a drilling device. A fixing plate is fixedly connected to the rear side of the top of the clamping platform, and a motor is fixedly connected to the front side of the fixing plate. By setting up the fixing plate and the motor, when the user needs to adjust the tilt angle of the opening device to achieve the machining of an angled hole, the motor on the fixing plate is activated, causing the support plate to tilt the entire drilling device. After the tilt angle reaches the required level, the clamping mechanism completely fixes the support plate. This solves the problem in the aforementioned devices where the drilling device, although adjustable up, down, left, right, and forward, cannot adjust the tilt angle, preventing the drilling of angled holes. However, some weighing instrument components, such as brackets and connectors, require angled holes for bolt connections and pipeline insertion, thus achieving the effect of auxiliary angle adjustment.

Description

Technical Field

[0001] This utility model relates to the field of weighing instrument processing technology, specifically to an adjustment mechanism for weighing instrument manufacturing. Background Technology

[0002] Weighing instruments are widely used in industries, agriculture, commerce, scientific research, medical and health care and other sectors. Weighing instruments use Hooke's Law or the lever balance principle of forces to determine the mass of objects.

[0003] For example, application number CN202420982290.3 describes a weighing instrument manufacturing processing device in the field of weighing instrument processing technology. It includes a processing table and a first slide groove. The top of the processing table is embedded in the first slide groove, and the inside of the first slide groove is a first slider. The inside of the first slide groove is a first threaded rod, and one end of the first threaded rod is equipped with a first motor. The top of the first slider is equipped with a fixed frame, and the top of the fixed frame is equipped with a second threaded rod.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can address some shortcomings of existing weighing instrument manufacturing processing devices, drilling of weighing instruments is mostly done manually, requiring manual clamping of the workpiece before drilling. This is not only time-consuming and labor-intensive but also reduces work efficiency. Furthermore, long-term use may cause hand injuries to workers, posing a safety hazard. Although the drilling device in the aforementioned equipment can be adjusted up, down, left, right, and forward and backward, it cannot adjust the tilt angle, making it impossible to process angled holes. However, some weighing instrument components, such as brackets and connectors, require angled holes for bolt connections and pipeline insertion operations. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide an adjustment mechanism for manufacturing weighing instruments, which has the advantage of auxiliary angle adjustment. This solves the problem that although the drilling device in the above-mentioned equipment can be adjusted up, down, left, right, and forward and backward, it cannot adjust the tilt angle, making it impossible for the drilling device to process oblique holes. However, some weighing instrument components, such as brackets and connectors, require oblique holes to achieve bolt connections and pipeline insertion operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustment mechanism for processing in the manufacture of weighing instruments, comprising a clamping platform, a support plate, and a drilling device. A fixing plate is fixedly connected to the rear side of the top of the clamping platform, a motor is fixedly connected to the front side of the fixing plate, the output end of the motor extends through to the back side of the fixing plate, the bottom of the front side of the support plate is fixedly connected to the output end of the motor, the back side of the drilling device is fixedly connected to the top of the front side of the support plate, and a clamping mechanism is fixedly connected to the back side of the clamping platform.

[0007] In a preferred embodiment of this utility model, the clamping mechanism includes a mounting plate, the bottom of the front side of the mounting plate is fixedly connected to the back side of the clamping platform, the front side of the mounting plate is in contact with the back side of the support plate, a cylinder is slidably connected to the inner wall of the mounting plate, the front side of the cylinder is fixedly connected to the bottom of the back side of the support plate, a cylinder is fixedly connected to the bottom of the back side of the mounting plate, the output end of the cylinder is fixedly connected to a first arc-shaped plate, a second arc-shaped plate is provided on the top of the first arc-shaped plate, and symmetrical moving mechanisms are movably connected to both sides of the back side of the mounting plate through pivot pins.

[0008] As a preferred embodiment of this utility model, the symmetrical moving mechanism includes a gear, the inner and outer sides of which are movably connected to the two sides of the back of the mounting plate via pins. A first toothed plate is fixedly connected to the front side of both sides of the first arc-shaped plate, and a second toothed plate is fixedly connected to the rear side of both sides of the second arc-shaped plate. The inner sides of the first and second toothed plates are meshed with the two sides of the gear.

[0009] As a preferred embodiment of this utility model, both sides of the back of the mounting plate are fixedly connected to U-shaped frames, and the inner walls of the first and second arc-shaped plates are slidably connected to the two ends of the surface of the U-shaped frames.

[0010] As a preferred embodiment of this utility model, a rubber block is fixedly connected to the inner side of the first arc-shaped plate and the second arc-shaped plate, and the inner side of the rubber block is in contact with the surface of the cylinder.

[0011] As a preferred embodiment of the present invention, the surface of the cylinder is provided with friction-enhancing grooves, and the friction-enhancing grooves are provided in a plurality of them and are distributed in a ring at equal intervals.

[0012] As a preferred embodiment of this utility model, the front of the fixing plate is provided with an angle groove, and a plurality of angle grooves are provided and distributed at equal intervals in an arc shape. A directional arrow is fixedly connected to the bottom of the front of the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a fixed plate and a motor, allows the user to adjust the tilt angle of the opening device to produce angled holes. The motor on the fixed plate is activated, causing the support plate to tilt the entire drilling device. Once the tilt angle reaches the required level, the clamping mechanism secures the support plate. This solves the problem in the aforementioned devices where the drilling device, while adjustable up, down, left, right, and forward / backward, cannot adjust the tilt angle, preventing the production of angled holes. However, some weighing components, such as brackets and connectors, require angled holes for bolt connections and pipeline insertion, thus providing auxiliary angle adjustment.

[0015] 2. This utility model, by setting up a clamping mechanism, allows the support plate and the drilling device to tilt together when the user starts the motor. Then, the cylinder is activated to push the first arc plate upward, and the second arc plate is moved downward through a symmetrical moving mechanism. Finally, the first and second arc plates clamp the cylinder, thereby fixing the support plate with external force. This prevents the vibration generated during drilling and the oblique pressure after the support plate and the drilling device tilt from being unable to withstand the self-locking force when the motor is turned off, thus preventing deviations in the accuracy of the drilled hole.

[0016] 3. By setting up a symmetrical moving mechanism, when the cylinder output end pushes the first arc plate to move upward, the first toothed plate rises together and drives the gear to rotate. Subsequently, the second toothed plate is driven by the gear to move in the opposite direction to the first toothed plate, thus driving the second arc plate to move downward. Finally, the first arc plate and the second arc plate move symmetrically to clamp the cylinder, thereby achieving the effect of using a single cylinder to make the first arc plate and the second arc plate move symmetrically at the same time.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, the present invention provides an adjustment mechanism for manufacturing weighing instruments, including a clamping platform 1, a support plate 2, and a drilling device 3. A fixing plate 4 is fixedly connected to the rear side of the top of the clamping platform 1, and a motor 5 is fixedly connected to the front side of the fixing plate 4. The output end of the motor 5 extends through to the back side of the fixing plate 4. The bottom of the front side of the support plate 2 is fixedly connected to the output end of the motor 5. The back side of the drilling device 3 is fixedly connected to the top of the front side of the support plate 2. A clamping mechanism 6 is fixedly connected to the back side of the clamping platform 1.

[0024] refer to Figure 2 and Figure 3 The clamping mechanism 6 includes a mounting plate 61. The bottom of the front side of the mounting plate 61 is fixedly connected to the back side of the clamping table 1. The front side of the mounting plate 61 is in contact with the back side of the support plate 2. A cylinder 62 is slidably connected to the inner wall of the mounting plate 61. The front side of the cylinder 62 is fixedly connected to the bottom of the back side of the support plate 2. A cylinder 63 is fixedly connected to the bottom of the back side of the mounting plate 61. The output end of the cylinder 63 is fixedly connected to a first arc plate 64. A second arc plate 65 is provided on the top of the first arc plate 64. Symmetrical moving mechanisms 7 are movably connected to both sides of the back side of the mounting plate 61 through shaft pins.

[0025] As a technical optimization of this utility model, by setting up a clamping mechanism 6, when the user starts the motor 5, the support plate 2 and the drilling device 3 are driven to tilt at an overall angle, and then the cylinder 63 is started to push the first arc plate 64 to move upward. Then, the second arc plate 65 is moved downward through the symmetrical moving mechanism 7, so that the first arc plate 64 and the second arc plate 65 clamp the cylinder 62, thereby fixing the support plate 2 under external force. This prevents the vibration force generated during drilling and the oblique pressure after the support plate 2 and the drilling device 3 are tilted from being unable to withstand the self-locking force when the motor 5 is turned off, thus preventing deviations in the accuracy of the drilled hole.

[0026] refer to Figure 3 The symmetrical moving mechanism 7 includes a gear 71. The inner and outer sides of the gear 71 are movably connected to the two sides of the back of the mounting plate 61 via pins. The front sides of the first arc plate 64 are fixedly connected to the first toothed plate 72, and the rear sides of the second arc plate 65 are fixedly connected to the second toothed plate 73. The inner sides of the first toothed plate 72 and the second toothed plate 73 are meshed with the two sides of the gear 71.

[0027] As a technical optimization of this utility model, by setting a symmetrical moving mechanism 7, when the first arc plate 64 is pushed upward by the output end of the cylinder 63, the first toothed plate 72 rises together and drives the gear 71 to rotate. Subsequently, the second toothed plate 73 is driven by the gear 71 to move in the opposite direction to the first toothed plate 72, thereby driving the second arc plate 65 to move downward. Finally, the first arc plate 64 and the second arc plate 65 move symmetrically to clamp the cylinder 62, thereby achieving the effect of using one cylinder 63 to make the first arc plate 64 and the second arc plate 65 move symmetrically at the same time.

[0028] refer to Figure 3 Both sides of the back of the mounting plate 61 are fixedly connected to the U-shaped frame 8, and the inner walls of the first arc plate 64 and the second arc plate 65 are slidably connected to the two ends of the surface of the U-shaped frame 8.

[0029] As a technical optimization of this utility model, by setting up the U-shaped frame 8, when the first arc plate 64 and the second arc plate 65 move, the inner walls of the first arc plate 64 and the second arc plate 65 slide along the trajectory of the U-shaped frame 8. Thus, the U-shaped frame 8 provides a fixed moving trajectory for the first arc plate 64 and the second arc plate 65, and enables stable meshing and transmission between the first toothed plate 72 and the second toothed plate 73 and the gear 71.

[0030] refer to Figure 3 A rubber block 9 is fixedly connected to the inner side of the first arc plate 64 and the second arc plate 65, and the inner side of the rubber block 9 is in contact with the surface of the cylinder 62.

[0031] As a technical optimization of this utility model, by setting a rubber block 9, when the arc plate clamps the cylinder 62, the rubber block 9 is deformed by pressure and closely fits the surface of the cylinder 62. By utilizing the high coefficient of friction and elastic properties of rubber, the thrust of the cylinder 63 is converted into sufficient frictional force to prevent the cylinder 62 from rotating, thereby locking the angle of the support plate 2.

[0032] refer to Figure 3 The surface of the cylinder 62 is provided with friction-enhancing grooves 10, and there are several friction-enhancing grooves 10 distributed in a ring at equal intervals.

[0033] As a technical optimization of this utility model, by setting the friction-enhancing groove 10, when the arc plate clamps the cylinder 62, the rubber block 9 is deformed by pressure and closely adheres to the surface of the cylinder 62. Due to the compression, the rubber block 9 is embedded in the friction-enhancing groove 10, forming a convex-concave fit. This effectively suppresses the relative rotation between the cylinder 62 and the rubber block 9 even under long-term drilling vibration.

[0034] refer to Figure 1 Angle grooves 11 are provided on the front of the fixing plate 4. Several angle grooves 11 are provided and are distributed at equal intervals in an arc shape. A pointing arrow 12 is fixedly connected to the bottom of the front of the support plate 2.

[0035] As a technical optimization of this utility model, by setting an angle groove 11 and a pointing arrow 12, the angle groove 11 and the pointing arrow 12 cooperate to provide a clear angle scale reference, which makes it easier for the user to adjust the drilling device 3 to the target angle, thereby improving the user's ease of operation.

[0036] The working principle and usage process of this utility model are as follows: When the user needs to machine oblique holes in the weighing instrument workpiece for subsequent installation or use, the motor 5 on the fixing plate 4 is started, causing the support plate 2 to tilt the drilling device 3 at the required angle. After the tilt angle reaches the desired level, the motor 5 is first turned off, allowing the support plate 2 and the drilling device 3 to be initially fixed by the self-locking mechanism of the motor 5 when it is turned off. Then, the cylinder 63 is started, pushing the first arc-shaped plate 64 upwards. Simultaneously, the first toothed plate 72 rises, driving the gear 71 to rotate, causing the second toothed plate 73 to be driven by the gear 71. The movement direction opposite to that of the first toothed plate 72 causes the second arc-shaped plate 65 to move downwards. Consequently, the first arc-shaped plate 64 and the second arc-shaped plate 65 move symmetrically to clamp the cylinder 62, thereby fixing the support plate 2 under external force. This achieves final fixation, thus preventing the vibration generated during drilling and the oblique pressure after the support plate 2 and the drilling device 3 are tilted from being unable to withstand the self-locking force when the motor 5 is turned off, which would cause deviations in the accuracy of the machined hole. At this point, the workpiece can be fixed on the clamping table 1, and then the drilling device 3 is started, finally making an oblique hole in the workpiece, thus having the advantage of auxiliary angle adjustment.

[0037] In summary, this adjustment mechanism for manufacturing weighing instruments, by setting up a fixed plate 4 and a motor 5, allows the user to adjust the tilt angle of the opening device to achieve the machining of oblique holes. The motor 5 on the fixed plate 4 is activated, causing the support plate 2 to tilt the drilling device 3. Once the tilt angle reaches the required level, the clamping mechanism 6 completely fixes the support plate 2 in place. This solves the problem in the aforementioned equipment where the drilling device, while adjustable up, down, left, right, and forward / backward, could not adjust the tilt angle, preventing the machining of oblique holes. However, some weighing instrument components, such as brackets and connectors, require oblique holes for bolt connections and pipeline insertion.
