Description

Technical Field

[0001] This utility model relates to the field of automatic feeding of drilling machines, and specifically to an automatic feeding device for drilling machines. Background Technology

[0002] In the production process of graphite bearing sleeves using a drilling machine, the traditional feeding method mainly relies on manual operation. Operators need to place the graphite bearing sleeves one by one onto the processing station of the drilling machine. This method has obvious drawbacks: on the one hand, manual feeding is inefficient and cannot meet the needs of large-scale production, especially when processing more than 10 or even 20 bearing sleeves in a single batch, frequent manual operation leads to high labor intensity; on the other hand, manual placement makes it difficult to ensure consistent positioning accuracy for each bearing sleeve, easily resulting in positional deviations and affecting drilling quality. Therefore, there is an urgent need for a device that can achieve automatic feeding and stable material delivery to solve the problems of low efficiency and poor accuracy of traditional manual feeding. Utility Model Content

[0003] This utility model provides an automatic feeding device for drilling machines to solve the problems of the prior art.

[0004] The purpose of this utility model can be achieved through the following technical solution: An automatic feeding device for a drilling machine includes: a feeding seat, an end limiting rod, and a feeding pushing assembly. The upper end of the feeding seat is inclined to the right and downward. A baffle plate is provided on the upper end surface of the feeding seat. The feeding pushing assembly includes a base plate, a cylinder, a first push plate, a second push plate, a guide rail, and a slider. The base plate is fixed to the lower end of the feeding seat and the right end is inclined upward. The cylinder body of the cylinder is mounted on the base plate. The piston rod of the cylinder is connected to the first push plate. The guide rail is fixed to the base plate. The slider is slidably disposed on the guide rail. The lower end of the second push plate is fixedly connected to the slider. The second push plate is connected to the front end of the first push plate. The vertical distance Ha from the upper end surface of the first push plate to the bottom of the end limiting rod is less than the outer diameter of the graphite bearing sleeve. The vertical distance Hb from the upper end surface of the second push plate to the bottom of the end limiting rod is greater than the outer diameter of the graphite bearing sleeve. When the piston rod of the cylinder is retracted, the lowest graphite bearing sleeve is located in the receiving groove formed by the second push plate and the first push plate.

[0005] In a further improvement, the baffle plate includes a fixed baffle plate and an adjustable baffle plate. The fixed baffle plate is fixed to the rear side of the upper end face of the feeding seat, and the adjustable baffle plate is slidably disposed on the front side of the upper end face of the feeding seat. The fixed baffle plate and the adjustable baffle plate form a material storage cavity, and a baffle plate adjustment handwheel is connected to one side of the adjustable baffle plate.

[0006] In a further improvement, the feeding seat is provided with a fixed shaft, the right side of the base is slidably sleeved on the fixed shaft, the left side of the feeding seat is provided with a lead screw, one side of the lead screw is fixedly connected to a left and right adjustment handwheel, a fixed nut is connected to the lead screw, the left side of the fixed nut is threadedly connected to a lead screw, the lower end of the lead screw is fixedly connected to an angle adjustment handwheel, and the upper end of the lead screw is rotatably connected to the base.

[0007] In a further improvement, both the fixed baffle and the adjustable baffle have an arc-shaped baffle portion extending from their lower ends and located on one side of the end limiting rod.

[0008] In a further improvement, the end limiting rod includes a vertical rod, a first connecting slider, a horizontal rod, a second connecting slider, and a stop rod. The vertical rod is fixedly connected to the feeding seat. One side of the first connecting slider is slidably sleeved on the vertical rod and fixed by bolts. The rear end of the horizontal rod is slidably disposed on the other side of the first connecting slider and fixed by bolts. One side of the second connecting slider is slidably sleeved on the front end of the horizontal rod and fixed by bolts. The stop rod is slidably sleeved on the other side of the second connecting slider and fixed by bolts.

[0009] Compared with the prior art, the advantages of this utility model's automatic feeding device for drilling machines are as follows:

[0010] The inclined surface drive and precise positioning structure of the receiving slot design, with the upper end face of the feeding seat tilted to the right, combined with the height difference between push plate one and push plate two, forms a stepped receiving slot that can accommodate only a single bearing sleeve. Gravity and mechanical positioning are used to achieve single material separation. The cylinder-driven cyclic pushing mechanism drives the push plate assembly to reciprocate along the guide rail through the extension and retraction of the cylinder piston rod. Combined with the blocking effect of the end limit rod, it realizes the automated cycle of pushing and replenishing materials without manual intervention. The highly efficient automated feeding can support multiple continuous processing with a single material storage, improving production efficiency and reducing labor intensity.

[0019] The following describes the embodiments and appendices. Figures 1-6 The technical solution of this utility model will be further described below.

[0020] Example 1

[0021] An automatic feeding device for a drilling machine includes: a feeding base 1, an end limiting rod 2, and a feeding pushing assembly 3. The upper end of the feeding base 1 is inclined downward to the right, and a baffle plate 11 is provided on the upper end surface of the feeding base 1. The feeding pushing assembly 3 includes a base plate 31, a cylinder 32, a first push plate 33, a second push plate 34, a guide rail 35, and a slider 36. The base plate 31 is fixed to the lower end of the feeding base 1 and its right end is inclined upward. The cylinder body of the cylinder 32 is mounted on the base plate 31, and the piston rod of the cylinder 32 is connected to the first push plate 33. The guide rail 35 is fixed. On the substrate 31, the slider 36 is slidably disposed on the guide rail 35. The lower end of the push plate 33 is fixedly connected to the slider 36. The push plate 34 is connected to the front end of the push plate 33. The vertical distance Ha from the upper end face of the push plate 33 to the bottom of the end limiting rod 2 is less than the outer diameter of the graphite bearing sleeve. The vertical distance Hb from the upper end face of the push plate 34 to the bottom of the end limiting rod 2 is greater than the outer diameter of the graphite bearing sleeve. When the piston rod of the cylinder 32 is retracted, the lowest graphite bearing sleeve is located in the receiving groove 4 formed by the push plate 34 and the push plate 33.

[0022] like Figures 1-6 As shown, the automatic feeding device in this embodiment achieves automatic feeding through the coordinated design of the inclined surface of the feeding seat and the feeding push assembly. Specifically, the upper end of the feeding seat 1 is inclined downward to the right, forming an inclined structure, allowing the graphite bearing sleeve to slide naturally down the inclined surface under the action of gravity. The baffle plate 11 on the upper end (including the fixed baffle plate 111 and the adjustable baffle plate 112) forms a storage cavity 113 for storing multiple graphite bearing sleeves (e.g., 10-20). When the bearing sleeves are stacked on the inclined surface, they are tightly arranged by gravity. In the feeding push assembly 3, the right end of the base plate 31 is inclined upward, forming an appropriate angle with the inclined surface of the feeding seat. Push plate 1 33 and push plate 2 34 are fixedly connected, and the vertical distances between their upper end surfaces and the bottom of the end limiting rod 2 are different: the vertical distance Ha from the upper end surface of push plate 1 33 to the bottom of the end limiting rod is less than the outer diameter of the graphite bearing sleeve, and the vertical distance Hb from the upper end surface of push plate 2 34 to the bottom of the end limiting rod is greater than the outer diameter of the graphite bearing sleeve. This height difference forms a specific receiving groove 4 structure—when the piston rod of cylinder 32 retracts, the graphite bearing sleeve at the bottom falls into the receiving groove between push plate 1 33 and push plate 2 34 (because the right end of the base plate is tilted, the right side of the receiving groove is upward, and the bearing sleeve is stably locked in it), while the bearing sleeve above is blocked by the bearing sleeve in the receiving groove (the height of push plate 1 is lower than the diameter of the bearing sleeve, and the upper bearing sleeve cannot pass through the gap between push plate 1 and the limiting rod), thus preventing mass falling.

[0023] Specific action procedures:

[0024] Initial state: The cylinder piston rod retracts, the push plate 33 is located on the left side of the base plate 31, and the receiving groove 4 carries the lowest graphite bearing sleeve, while the upper bearing sleeve is blocked in the storage cavity.

[0025] Pushing the feed: The cylinder piston rod extends, driving push plate 33 to slide to the right along guide rail 35, while push plate 34 moves forward simultaneously. Since the height Ha of push plate 33 is less than the diameter of the bearing sleeve, the bearing sleeve above it is blocked by the end limiting rod 2, and only a single bearing sleeve in the slot is pushed to the drilling station (top position) of the drilling machine, achieving precise feeding.

[0026] Return stroke refill: The cylinder piston rod retracts, and pusher plate 33 retracts to the left. At this time, pusher plate 34 returns to directly below the end limit rod 2. Because the height Hb of pusher plate 34 is greater than the diameter of the bearing sleeve, the bearing sleeve in the storage cavity slides down the inclined plane under the action of gravity, and the bottommost one falls into the receiving groove 4, completing one refill. This cycle can realize the automatic batch feeding of 10-20 bearing sleeves without the need for manual placement, significantly improving feeding efficiency and stability.

[0027] As a further preferred embodiment, the baffle plate 11 includes a fixed baffle plate 111 and an adjustable baffle plate 112. The fixed baffle plate 111 is fixed to the rear side of the upper end face of the feeding seat 1, and the adjustable baffle plate 112 is slidably disposed on the front side of the upper end face of the feeding seat 1. The fixed baffle plate 111 and the adjustable baffle plate 112 form a material storage cavity 113. A baffle adjustment handwheel 5 is connected to one side of the adjustable baffle plate 112.

[0028] A fixed baffle plate 111 is fixed to the rear side of the feeding seat, and an adjustable baffle plate 112 is mounted on the front side via a sliding structure, forming a storage cavity 113 between the two. Rotating the baffle adjustment handwheel 5 causes the adjustable baffle plate 112 to slide along the end face of the feeding seat, thereby changing the width of the storage cavity to accommodate graphite bearing sleeves of different outer diameters. This ensures that the bearing sleeves are stably stacked on the inclined surface, preventing the bearing sleeves from tilting or jamming due to excessive clearance, and improving the versatility of the device. The adjustment principle of the baffle adjustment handwheel 5 is the same as that of the left and right adjustment handwheel 6.

[0029] As a further preferred embodiment, the feeding seat 1 is provided with a fixed shaft 115, the right side of the base 31 is slidably sleeved on the fixed shaft 115, the left side of the feeding seat 1 is rotatably provided with a lead screw 116, one side of the lead screw 116 is fixedly connected with a left and right adjustment handwheel 6, a fixing nut 117 is connected to the lead screw 116, the left side of the fixing nut 117 is threadedly connected with a lead screw 118, the lower end of the lead screw 118 is fixedly connected with an angle adjustment handwheel 7, and the upper end of the lead screw 118 is rotatably connected to the base 31.

[0030] The substrate 31 is slidably mounted on the fixed shaft 115 on the right side, and connected to the loading seat on the left side via lead screw 116 and lead screw 2 118. Rotating the left and right adjustment handwheel 6 drives lead screw 116 to rotate, causing the fixed nut 117 to move left and right, thereby adjusting the horizontal position of the substrate 31; rotating the angle adjustment handwheel 7 drives lead screw 2 118 to rotate, changing the tilt angle of the substrate 31 (because the upper end of lead screw 2 is connected to the substrate). The position and tilt of the loading push component can be flexibly adjusted according to the work position and angle requirements of different drilling machines to ensure that the pushed bearing sleeve accurately reaches the top position of the drilling machine, improving the adaptability of the device to different equipment.

[0031] As a further preferred embodiment, both the fixed baffle plate 111 and the adjustable baffle plate 112 have arc-shaped baffle portions 119 extending from their lower ends and located on one side of the end limiting rod 2. When the bearing sleeve slides down the inclined surface to the end limiting rod position, the arc-shaped baffle portion guides the bearing sleeve to fall smoothly into the receiving groove 4, avoiding the bearing sleeve from getting stuck or jumping out due to the right-angle edge, thus improving the smoothness and reliability of the feeding process.

[0032] As a further preferred embodiment, the end limiting rod 2 includes a vertical rod 21, a first connecting slider 22, a horizontal rod 23, a second connecting slider 24, and a stop rod 25. The vertical rod 21 is fixedly connected to the feeding seat 1. One side of the first connecting slider 22 is slidably sleeved on the vertical rod 21 and fixed by bolts. The rear end of the horizontal rod 23 is slidably disposed on the other side of the first connecting slider 22 and fixed by bolts. One side of the second connecting slider 24 is slidably sleeved on the front end of the horizontal rod 23 and fixed by bolts. The stop rod 25 is slidably sleeved on the other side of the second connecting slider 24 and fixed by bolts.

[0033] The vertical rod 21 is fixed to the feeding seat. Connecting slider 1 22 can slide up and down along the vertical rod and is fixed with bolts. The rear end of the horizontal rod 23 is slidably connected to connecting slider 1 (adjustable front and back). Connecting slider 24 slides left and right along the front end of the horizontal rod. The stop rod 25 is slidably connected to connecting slider 2 (adjustable up and down). By loosening / tightening the bolts, the height, front and back position, and left and right position of the stop rod 25 can be adjusted respectively. For graphite bearing sleeves of different specifications (such as different heights or lengths), the position of the stop rod 25 can be flexibly adjusted to ensure that its height difference with push plate 1 33 and push plate 2 34 is precisely matched, realizing the limiting and guiding of bearing sleeves of different sizes, and enhancing the applicability of the device.

[0034] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
