Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology, specifically a felt clamping tool. Background Technology

[0002] Existing plastic parts often have protrusions with a semi-circular cross-section. During processing, felt needs to be attached to the semi-circular surface of these protrusions. Due to their small size, this is usually done manually. However, in actual production, because the protrusions are semi-circular and the felt has a certain degree of rigidity, it is difficult to achieve uniformity in the force and evenness after manual attachment. As a result, some of the felt tends to lift up after attachment, leading to product defects. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] See Figures 1 to 5 This utility model provides a felt clamping fixture, including a horizontally arranged base and a first clamping assembly and a second clamping assembly respectively disposed on the base; the first clamping assembly includes a horizontally arranged cover plate and a vertically arranged adjusting member, the adjusting member being connected to the base and the cover plate respectively to adjust the distance between the cover plate and the base; the second clamping assembly includes a fixed block disposed on the upper surface of the base, a movable block disposed opposite to the fixed block, and a driving cylinder fixed on the upper surface of the base, the driving end of the driving cylinder being connected to the movable block to control the movable block to move closer to or away from the fixed block.

[0027] The beneficial effects of this utility model are:

[0028] This utility model provides a felt clamping fixture, including a horizontally arranged base and a first clamping assembly and a second clamping assembly respectively disposed on the base. The first clamping assembly includes a horizontally arranged cover plate and a vertically arranged adjusting member, which is connected to the base and the cover plate respectively to adjust the distance between the cover plate and the base. The second clamping assembly includes a fixed block disposed on the upper surface of the base, a movable block disposed opposite to the fixed block, and a drive cylinder fixed to the upper surface of the base. The drive end of the drive cylinder is connected to the movable block to control the movable block to move closer to or away from the fixed block. The first clamping assembly is used to initially fix rows of products. Felt is manually attached to and pressed onto products with a semi-circular cross-section protrusion, and then transferred to the second clamping assembly. The protrusion extends between the fixed block and the movable block. The movable block moves towards the fixed block to clamp the felt located on the protrusion. After clamping for a preset time, the felt and protrusion can be more tightly fitted, improving the product processing qualification rate.

[0029] Preferably, a flexible layer is provided on the opposite sides of both the fixed block and the movable block.

[0030] As described above, flexible layers are provided on the opposite sides of the fixed block and the movable block to avoid rigid collisions with the protrusions, which could cause deformation or even damage to the protrusions.

[0031] Preferably, the flexible layer is composed of soft foam of a predetermined thickness.

[0032] As described above, the flexible layer is made of soft foam of a preset thickness. The thickness can be set according to the cylinder extrusion force and the bearing capacity of the protrusion (plastic material), as long as it does not damage the protrusion when clamped.

[0033] Preferably, the base is provided with two limiting blocks, which are respectively provided on both sides of the fixed block, and the lower ends of the opposite surfaces of the two limiting blocks form a limiting groove for limiting the movement range of the movable block.

[0034] As described above, setting a limit block and having a limit groove to limit the range of movement of the moving block ensures clamping accuracy, that is, improves clamping precision.

[0035] Preferably, the lower surface of the cover plate has a stepped surface, and the height of the stepped surface and the upper surface of the base is adapted to the thickness of the product to be clamped.

[0036] As can be seen from the above description, through the specific design, the step surface has a certain step width, and can also form a certain degree of positioning for the product to be clamped, which facilitates quick clamping.

[0037] Preferably, there are two drive cylinders, both of which are located on the side of the movable block away from the fixed block and act together on the same movable block.

[0038] As can be seen from the above description, through the specific design described above, the two driving cylinders act on the same moving block simultaneously, which can ensure that the moving block is subjected to balanced force and will not deviate, thereby ensuring the moving stability and clamping stability of the moving block.

[0039] Preferably, it further includes a controller and a timer electrically connected to the controller; the controller is electrically connected to the drive cylinder.

[0040] As described above, by adding a controller and a timer, and setting a duration threshold on the controller, the controller receives an external signal (such as a signal generated by a button switch), and controls the drive cylinder to move, pushing the movable block toward the fixed block. After the movable block moves into position, it sends feedback to the controller, which then triggers the timer to start timing and sends real-time feedback back to the controller. The controller compares the timing on the timer with the preset duration threshold. When the duration threshold is reached, the controller controls the drive cylinder to move in the opposite direction, causing the movable block to move in the opposite direction, thus increasing the distance between the movable block and the fixed block, making it easier to remove the product.

[0041] Preferably, it also includes an alarm and a ranging sensor that are electrically connected to the controller, the ranging sensor being embedded on the side of the fixed block and the movable block opposite to each other.

[0042] As described above, by adding a distance sensor, the actual distance between the fixed block and the moving block is measured and fed back to the controller. The controller has a distance threshold range set. If the actual distance is less than or greater than the distance threshold range, an abnormal situation is indicated, and an alarm will be triggered. Specifically, when the actual distance is less than the minimum value of the distance threshold range, cylinder malfunction may occur, resulting in excessive clamping. Since the product protrusion is made of plastic, it is highly susceptible to deformation and damage. When the actual distance is greater than the maximum value of the distance threshold range, cylinder malfunction may occur, resulting in excessive separation. The moving block may easily detach from the limit block, affecting operational stability.

[0043] Example 1

[0044] See Figures 1 to 5 The present invention provides a felt clamping fixture, comprising a horizontally arranged base 1 and a first clamping component 2 and a second clamping component 3 respectively disposed on the base 1;

[0045] The first clamping assembly 2 includes a horizontally arranged cover plate 21 and a vertically arranged adjusting member 22. The adjusting member 22 is connected to the base 1 and the cover plate 21 respectively to adjust the distance between the cover plate and the base; the adjusting member 22 is a fastening screw. There are two adjusting members 22.

[0046] The second clamping assembly 3 includes a fixed block 31 disposed on the upper surface of the base 1, a movable block 32 disposed opposite to the fixed block 31, and a drive cylinder 33 fixed on the upper surface of the base. The drive end of the drive cylinder 33 is connected to the movable block 32 to control the movable block to move closer to or away from the fixed block.

[0047] The number of driving cylinders 33 is two, both located on the side of the movable block 32 away from the fixed block and acting together on the same movable block. The simultaneous action of the two driving cylinders on the same movable block ensures that the movable block is subjected to balanced force and will not shift, thereby ensuring the movement stability and clamping stability of the movable block.

[0048] The first clamping component is used to initially fix the rows of products 4. The felt is attached to the product with a semi-circular cross-section protrusion 41 by manual means and manually pressed. Then it is transferred to the second clamping component. The protrusion extends between the fixed block and the movable block. The movable block moves towards the fixed block to clamp the felt on the protrusion. After clamping for a preset time, the felt and the protrusion can be more tightly attached, improving the product processing qualification rate.

[0049] Both the fixed block 31 and the movable block 32 have flexible layers 34 on their opposite sides. The flexible layers 34 are made of soft foam of a preset thickness. The thickness can be determined based on the cylinder's compressive force and the bearing capacity of the protrusion (made of plastic), ensuring that the protrusion is not damaged during clamping. The presence of flexible layers on the opposite sides of the fixed and movable blocks prevents rigid collisions with the protrusion, thus avoiding deformation or even damage to the protrusion.

[0050] The base 1 is provided with two limiting blocks 11, which are respectively arranged on both sides of the fixed block 31, and the lower ends of the opposite surfaces of the two limiting blocks 11 form limiting grooves 111 for limiting the movement range of the movable block. The setting of limiting blocks and the limiting grooves for limiting the movement range of the movable block ensures clamping accuracy, that is, improves clamping precision.

[0051] The lower surface of the cover plate 21 has a stepped surface 211, and the height of the stepped surface and the upper surface of the base is adapted to the thickness of the product 4 to be clamped. The stepped surface has a certain step width, which can also form a certain degree of positioning for the product to be clamped, facilitating quick clamping.

[0052] Example 2

[0053] Based on the above embodiment one, it also includes a controller and a timer electrically connected to the controller; the controller is electrically connected to the drive cylinder. By adding a controller and a timer, a duration threshold is set on the controller. When the controller receives an external signal (such as a signal generated by a push-button switch), the controller controls the drive cylinder to move, pushing the movable block toward the fixed block. After the movable block moves into position, it feeds back to the controller, which triggers the timer to start timing and feeds back to the controller in real time. The controller compares the timing on the timer with the preset duration threshold. When the duration threshold is reached, the controller controls the drive cylinder to move in the opposite direction, causing the movable block to move in the opposite direction, increasing the distance between the movable block and the fixed block, making it easier to remove the product.

[0054] Preferably, the device further includes an alarm and a distance sensor, both electrically connected to the controller. The distance sensor is embedded on the side of the fixed block and the movable block opposite to each other. By adding the distance sensor, the actual distance between the fixed block and the movable block is measured and fed back to the controller. The controller sets a distance threshold range. If the actual distance is less than or greater than the distance threshold range, it indicates an abnormal situation, and the alarm will be triggered. That is, when the actual distance is less than the minimum value of the distance threshold range, the cylinder may malfunction, resulting in excessive clamping. Since the product protrusion is made of plastic, it is very easy for the protrusion to deform or be damaged. When the actual distance is greater than the maximum value of the distance threshold range, the cylinder may malfunction, resulting in excessive separation. The movable block may easily detach from the limit block, affecting operational stability.

However, the above embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model.
